- P2189is a DTC code that can occur in your Hyundai Santa Fe. It indicates the air fuel mixture is too lean at idle, specifically in bank 2 (we’ll cover how to find bank 2 later). Its is different from the much more common P0174, which indicates that bank 2 is lean at any engine speed.
How do I fix error code P2189?
What repairs can fix the P2189 code?
- Repair of a leaking air intake.
- Replacement of a faulty gas cap seal.
- Repair or replacement of leaking exhaust system components.
- Repairing a mechanical issue in one or more of the bank 2 fuel injectors.
- Replacement of a faulty manifold absolute pressure sensor.
How do I fix error code P2187?
What repairs can fix the P2187 code?
- Repairing leaks in hoses, such as the EVAP system hoses or vacuum hoses.
- Repairing leaks in the exhaust system.
- Replacing the fuel filter, fuel pump, or fuel pressure regulator.
- Replacing the gas or oil filler caps.
- Replacing the O2, MAP, or mass airflow sensors.
What is code P2189?
OBD-II Code P2189 is defined as a System Too Lean at Idle. The engine control module (PCM) uses multiple sensors to determine the required amount of fuel needed to keep the engine running efficiently at idle. If the PCM cannot achieve the desired balance between fuel and air, it will set code P2189.
What is code P2187?
P2187 code indicates that your vehicle’s computer detected a potential issue with the fuel mixture at idle. In an internal combustion engine, the air-fuel mixture is controlled by the powertrain control module (PCM).
What causes code P0507?
The P0507 code is triggered when the Engine Control Module (ECM) detects that the engine is idling higher than the specified idle rpm range. The standard engine idle is usually between 600-800rpm based on the model of the vehicle.
Can a bad O2 sensor cause a car to run lean?
Yes the O2 sensor can cause the vehicle to run lean. What the O2 sensor does is read the amount of air entering the engine and sends that information to the computer, the computer reads this information and determines how much fuel the engine needs.
Is it bad to run an engine lean?
In combustion engines, ‘ running lean’ goes beyond using gas efficiently. In effect, that status makes the engine perform with less gasoline than it needs to operate properly, and it increase the amount of friction between the engine’s moving parts. Running lean can damage an engine.
How do I fix code P2096?
What repairs can fix the P2096 code?
- Repairing a vacuum or other hose/line leak.
- Replacing the catalytic converter.
- Replacing the fuel filter, fuel pump, or fuel pressure regulator.
- Replacing the oxygen or mass airflow sensor.
- Replacing the spark plugs.
What does System Too Lean at Idle Bank 1 mean?
The P2188 “System Too Lean at Idle Bank 1” definition indicates that there is too much air and too little fuel in the air-fuel ratio detected by the ECM during engine idle.
P2187 P2189 Hyundai
If you discover a Hyundai issue code (P2187 or P2189), don’t immediately start throwing components at the problem. The two codes P2187- bank 1 system lean and P2189- bank 1 system lean may take you down the incorrect road, leading you to believe that you have a fuel supply problem when in fact you do not. The majority of do-it-yourselfers begin by changing the gasoline filter, checking the fuel pressure, or cleaning the fuel injectors, among other things. However, a defective EVAP system purge valve might be the source of these two P2187 and P2189 Hyundai error codes.
By remaining open for an extended period of time, the intake continues to draw fuel vapors from the charcoal canister.
Cracks in the vacuum line connecting the charcoal canister to the valve, as well as the vacuum hose connecting the valve to the intake, can occur in these valves.
If this is the case, try pinching off the vacuum line leading to the canister purge valve to see if the results alter.
If your fuel trims are low or negative, do the same approach on your car as well.
If that is successful, the valve should be replaced.

My wife’s 2007 Hyundai Entourage was driving with the check engine light lit. I looked for signs of vacuum leakage. There were none found. I replaced the MAF sensor and restarted the computer to make it work again. I let the van warm up to operating temperature before driving it for 30 miles without seeing the check engine light come on. I parked the car in the driveway and turned off the engine for two hours to let it cool down. After that, I started the car, and the check engine light came on right away.

P2189 System Too Lean at Idle (Bank 2)
Don Bowman contributed to this article. At idle, the ASE Certified Automotive Technician System is too lean (Bank 2)
What does that mean?
This diagnostic problem code (DTC) is a general powertrain code that may be seen on many vehicles. Although particular repair processes may alter significantly depending on the model, it is called general since it applies to all makes and models of automobiles manufactured after 1996. This is a code that is unclear in and of itself. It might be difficult to crack a code if you do not have a diagnostic method. During the past two starts, the engine management computer has detected an issue with the fuel mixture at idle, which has been corrected.
An extensive variety of factors might contribute to the occurrence of such an event.
However, the method is not difficult.
Please keep in mind that this code is the same as P2187.
Symptoms
Because of the large variety of options, it is possible that the difficulties stated will or will not be present. However, it is critical to pay close attention to the symptoms that are noticed and to make a note of which symptoms arise and when they do so in order to formulate a diagnostic approach.
- When the vehicle is at a standstill, it misses
- It is difficult to start, especially when it is hot
- Idle time is quite irregular
- Additional codes can help identify the source of the original P2189 error
- Whistling sounds are heard. Lower turbo boost numbers
- The smell of gasoline
Potential Causes of P2189 DTC
- Gas cap seal failure
- Faulty oxygen sensor (front)
- Faulty oxygen sensor (rear). Oil filler cap that is leaking or has come loose
- Air flowing into the intake manifold downstream of the Mass Airflow sensor due to the manifold itself, vacuum hoses that are disconnected or fractured, a leaky MAP sensor, and other causes are listed below. leak at turbo bypass or it is jammed open
- Power brake booster hose
- Or leak in the exhaust valve assembly (EVAP system) MAP sensor that is not working properly
- Canister purge valve for EVAP canisters
- Leak from the fuel injector
- The fuel pressure regulator is malfunctioning
- Exhaust system leaks are a common occurrence. Variable camshaft timing that is not working properly
- ECM (engine management computer) malfunctioning
- Faulty oxygen preheating system (front)
- Clogged fuel filter
- Deterioration of the fuel pump, resulting in reduced pressure
- A faulty mass air flow sensor has been identified.
Diagnostic / Repair Steps
Your plan for identifying the source of the problem begins with a test drive and careful monitoring of any symptoms that appear. The next step is to utilize a code scanner (which can be found at any auto parts store) to look for any further codes that may exist. The computer has programmed the code P2189, which indicates that the fuel mixture is low when the engine is running at idle. However, any component that malfunctions inside this loop and has the potential to result in a lean mixture will also be set in code in addition to the main code.
In other words, the fuel mixture is not lean, and the computer or oxygen sensor is in charge of generating the error code and setting it.
These sensors provide information on the quantity of free oxygen remaining in the exhaust after ignition, which is used to calculate the fuel-to-air ratio.
A rough idle or one of the other symptoms should be checked out first, and then the most likely reason should be investigated. Unmetered air is entering the intake manifold, or there is a lack of fuel pressure in the system:
- Check the fuel cap for fractures, seal failure, and proper operation. Lift the hood and check that the oil filler cap is securely fastened
- First and foremost, if there are any extra codes, they should be examined. Start looking for air leaks at the mass airflow sensor and work your way down the line. Cracks or loose connections in the hose or connection between the sensor and the intake manifold, all the way to the manifold, should be checked before continuing. Check all of the vacuum hoses that are connected to the intake manifold, including the one that connects to the vacuum brake booster, thoroughly. Check the hoses leading to the MAP sensor and any hoses leading to the turbocharger, if one is present. While the engine is running, spray a fine mist over the base of the intake manifold and the point where the two pieces of the manifold come together if it is a two-piece design. Check for leaks into the manifold by spraying around the base of the EGR. If a leak is discovered, the engine’s rotational speed will rise. Check for leaks in the PCV valve and the hose
- Fuel injectors should be inspected for exterior fuel leakage. Pulling the vacuum hose from the fuel pressure regulator and shaking it will reveal whether or not fuel is present. If this is the case, it should be replaced. Install a fuel pressure tester on the schrader valve on the fuel supply rail to the injectors after shutting down the engine and starting it. Start the engine and take note of the fuel pressure at an idle and at 2500 rpm, then stop the engine. Compare these values to the recommended fuel pressure for your car that you may find online. If the volume or pressure is out of range, the pump or filter should be replaced.
The remaining components must be examined and programmed by a service facility that is equipped with a Tech 2 scanner and programmer.

P2189 Hyundai Santa Fe: Lean Condition at Idle (Bank 2)
This diagnostic trouble code (DTC) can arise in your Hyundai Santa Fe. When this occurs, it signals that the air fuel mixture is excessively lean at idle, notably in bank 2 (we’ll discuss how to locate bank 2 later). It differs from the considerably more frequent P0174, which indicates that bank 2 is lean at any engine speed, which indicates that bank 2 is rich. In this section, you can find the technical definition for P2189, ‘System too lean at idle: Bank 2.’ The code is generated when the oxygen sensor on Bank 2 (often sensor 1) detects that the air fuel combination is too lean and generates an error.
It is recommended that you use 14.7 parts air to 1 part gasoline as the optimal air/fuel combination (14.7:1) A lean air-fuel mixture indicates that your automobile or truck has too much air in relation to the amount of fuel it is running on.
Bank 2 Location:Hyundai Santa Fe
Bank one of the engine is the section of the engine that contains the second cylinder. P2189 can only be diagnosed if you know what it is and how to correctly recognize it. Because there is only one bank to deal with on inline engines, it is not necessary to know this information. However, with V6 and V8 engines, there are two cylinder heads and, as a result, two banks of cylinders. It is necessary to establish which side of the engine has bank 2 if you have the code P2189, unless you also have the code P2187, which indicates a lean state at idle for the first cylinder.
Here’s how to figure out where Bank 2 is located.
Symptoms
P2189 is related with a number of symptoms, some of which are listed below. The severity of the symptoms will vary depending on how far the air fuel combination has strayed from the ideal.
- Rough idle
- Difficult or no start
- Misfiring
- There is hissing/whistling emanating from the engine bay (which suggests that a vacuum leak is the source of the problem)
- And a gaseous odor
P2189 Causes:Hyundai Santa Fe
Following are some factors that might cause your Santa Fe’s engine to run excessively lean at idle, resulting in the P2189 code in bank 2. The majority of them are simple to verify, but there are a large number of them. Here are a few of the most often encountered:
- Low fuel pressure (due to blocked filter or defective pump)
- Vacuum leak
- Exhaust leak
- Fuel injection leak
- Fuel Pressure Regulator
- Fuel Pressure Low MAF sensor failure
- Faulty gas cap
- Faulty EVAP purge valve
P2189 Diagnosis:Hyundai Santa Fe
Here are some actions you may take to diagnose P2189 in your Santa Fe at home using the information provided. With the exception of P2189, there were hopefully no additional codes thrown at the end of the session. The fact that there is a problem is a positive thing since it makes diagnosing the problem much easier. For example, if the code is connected to an oxygen sensor, the oxygen sensors should be the first thing to look at. If it’s an EVAP code, the first thing to look at is the EVAP system.
We want to concentrate on issues that would lead ONLY ONE BANK to be in a state of financial distress.
It would imply that a faulty fuel injector or oxygen sensor is extremely likely to have occurred. On the bank 2 side of the engine, an exhaust leak or vacuum leak where the intake manifold meets the cylinder head might potentially be a contributing factor.
Super Easy Stuff
- Check to check that the gas cap is securely fastened all of the way down. The fact that you’ve received the check fuel cap warning a few times prior to receiving this code implies that a new fuel cap may be necessary, or that there is an EVAP leak. Oil Cap – P2189 has been reported to occur when there is no oil cap present, or if the oil cap is unsecured. Take a second to double-check it as soon as possible
- Gas smells surrounding the fuel injectors might indicate that one or more fuel injectors are leaking and need to be repaired or replaced. It might also suggest that your Santa Fe is suffering from an EVAP problem. Keep your ear out for a hiss – It is possible that a vacuum leak is causing the hissing or whistling sound emanating from the engine.
Look for Leaks
Vacuum leaks enable more air to enter your Santa Fe’s combustion chamber than the PCM is calling for. Because the air is unmetered, this means that there is more air in your Santa Fe’s combustion chamber than the PCM believes is going into it. When the O2 sensors detect the air fuel mixture at idle, the P2189 error code is generated.
- Evaluate and tighten all of the hoses leading to and from the intake manifold for rust, damage, and loose connections. Inspect the MAF sensor (if appropriate) for leaks in the area surrounding it. To determine if the PCV valve and hose are leaking, check them both.
Carb cleaner can be used to clean the areas around these areas. If the engine RPM increases as a result of the vacuum leak, you have discovered the probable cause of P2189.
Fuel System
If there is insufficient fuel pressure, there will be insufficient gasoline in the air fuel combination, resulting in the engine running lean. There are a variety of factors that might contribute to a decrease in fuel pressure.
- The following are possible causes of P2189 ‘Bank 1’: Bad Fuel Filter
- Bad Fuel Pump
- Clogged/Leaking Injector (particularly probable on a V6 or V8 where P2189 ‘Bank 1’ is thrown but P2189 ‘Bank 2’ is not thrown)
- And a faulty ignition switch.
Lower fuel pressure will be produced by a faulty fuel pump or fuel filter. However, you’d most likely receive P2187 as a result of that. Here’s an example of how to check fuel pressure.
Sensors
If there doesn’t appear to be anything physically wrong with the car, it’s possible that one of your Santa Fe’s sensors is malfunctioning and causing the problem.
- A faulty oxygen sensor would produce an erroneous air/fuel measurement, resulting in the occurrence of P2189. A faulty MAF or MAP sensor will fail to accurately measure the amount of air entering the engine, resulting in the engine running too lean or too rich. However, in this instance, it is too slim.
Conclusion:Hyundai Santa Fe P2189
As you can see, there are a variety of difficulties that might cause the Hyundai Santa Fe to display the P2189 code. This will be greatly dependent on whether or if there were any additional codes present, notably P2187 or an oxygen sensor-related code, and how you go about combating them.

P2187 – Meaning, Causes, Symptoms, & Fixes
At idle, Bank 1 either has too much air or not enough fuel.
What Does P2187 Mean?
Combustion engines operate most efficiently when the air-to-fuel mixture ratio is maintained at 14.7 parts air to one part fuel. Lean conditions arise when the air-fuel mixture contains 14.7 parts air to 1 part fuel. Code P2187 is triggered when this situation is detected at idle on bank 1, and it indicates that the air-fuel mixture has become too lean. Bank 1 is the single bank in a 4-cylinder engine, and if the engine is in a ‘V’ layout, it is the bank with cylinder 1. In addition to vacuum leaks, which bring more air into the air-fuel mixture, a weak fuel system, which does not inject enough fuel into the air-fuel combination, can result in a lean situation as a result of a weak fuel system.
When these modifications become excessively big while the vehicle is idling, the code P2187 is activated.
What Are The Symptoms Of Code P2187?
- Check The engine light is illuminated
- There are more codes
- Lack of engine power
- Rough idle
- High idle
- Hard or prolonged start
- Engine misfiring
- And other symptoms. Noise coming from the engine compartment
- Hissing or whistling.
*In certain circumstances, there are no evident unfavorable effects.
What Is The Cause Of Code P2187?
- Clean or malfunctioning mass airflow sensor
- PCV hoses, vacuum hoses, and the intake manifold gasket all have vacuum leaks. The oil cover has not been attached. Fuel pump that is not working properly
- Fuel injectors that are clogged or filthy
- Fuel filter that is clogged
- Exhaust leak faulty oxygen sensor
- Faulty air-fuel ratio sensor
- Faulty oxygen sensor
How Serious Is Code P2187? – Moderate
Driving a car with the P2187 code for a short amount of time is OK; however, driving a vehicle with this code for a longer period of time might cause the engine to overheat and cause internal engine damage.
Code P2187 Common Diagnosis Mistakes
When diagnosing P2187, it is critical that the full diagnostic process be completed in its entirety. Many individuals will immediately replace the air-fuel sensor or oxygen sensor if they receive a bad reading; however, the main reason is frequently a filthy or malfunctioning mass air flow sensor or vacuum leak, which causes the O2 or A/F sensor to read differently to compensate.

- Remove any further codes that may be present in addition to P2187 by using FIXD and turning off your Check Engine Light. Code P2187 should be diagnosed with any other codes that may be present since they may be associated with this problem. Examine the freeze frame data in order to determine the source of the problem
- Check to see that the engine oil cover is properly placed and tightly secured
- Check for leaks in any vacuum lines and hoses, and double-check that they are all securely linked together. While driving, you will hear a hissing sound that indicates the presence of a leak. However, it may be difficult to detect while the engine is running. Also, make certain that the engine oil cover is properly placed and tightened. Look out this comprehensive guide to discovering and correcting vacuum leaks if you believe you have one but are having difficulty locating it
- After reconnecting any disconnected vacuum lines and replacing any broken vacuum lines that are leaking, you may utilize FIXD to clear the P2187 check engine light code. If the check engine light (code P2187) illuminates again, check the fuel pressure and compare it to the standard for your vehicle’s fuel pressure when at idle. If the fuel pressure is low, check to be that the fuel pressure regulator is correctly attached and operating properly before continuing. If your fuel pump is working normally, replace it
- If your fuel pressure is within specifications, remove the mass airflow sensor and clean it using mass airflow cleaner or contact cleaner
- After you have checked that there are no vacuum leaks, that the mass airflow sensor is clean, and that your fuel system is running properly, check the exhaust for leaks before checking the Air Fuel Ratio Sensors or the Oxygen sensors. If you discover any leaks, have them fixed immediately. If the problem remains at this point, you may want to try changing your A/F sensor or your oxygen sensors.

Car Questions
Hello, Scotty. Thank you so much for what you are doing. I was a first-time driver, and I gained a great deal from you. My first automobile was a 2008 Hyundai Santa Fe with a 2.7L V6 engine that I purchased around 10 000 miles ago. It was my first car. It has now traveled 169 000 miles. The Check Engine light came on about 8 000 miles ago, about 2-3 weeks after I changed the oil and cleaned the fuel injectors, and the P2187 and P2189 codes were shown (System too lean ai Idle Bank 1 and Bank 2).
- After two or three months of driving, the identical error number appeared again.
- Fortunately, after a few of weeks, the check engine light came back on and switched off by itself once more.
- While driving up a short hill, the car began to heat up, the check engine light on, and I detected a strong scent of gasoline.
- The check engine light turned off by itself, and the car was driving normally.
- The same codes were returned again and again.
- I cleaned the MAF sensor and throttle body using a cleaner that was recommended by the manufacturer.
- However, after a few of weeks, the identical code appeared again.
I attempted to remove the code, but it reappeared the next day.
Occasionally, the motor would simply shut off before I could turn it off.
When I examined the oil level, I observed that the engine had begun to consume oil.
In addition, I detected the fragrance of gasoline.
The air filter is in good condition.
The automobile began to drive considerably more smoothly, with no hesitation and no shaking.
As of now, I haven’t looked at the code.
So, what do you recommend I do?
-On a handful of occasions after refueling the automobile, the car would not start immediately after.
I double-checked it when the battery was unplugged, and I figured that once the car was started, the computer would make the necessary adjustments.
Is this a sign that the throttle body has failed?
Or even an oxygen sensor?
I was going between cities and had to drive for a lengthy period of time on a highway with low gasoline levels before I could find a gas station.
Is it possible that the fuel pump has failed, and if so, how can I determine this?
I observed some black patches on the surface of the head gasket.
When I initially got the automobile, I made the mistake of driving at a high rate of speed, virtually at maximum speed on a highway for a lengthy period of time, in order to test the limitations of the vehicle.
In addition, for a variety of reasons, I kept the car idling with the air conditioning on for lengthy periods of time in Arizona.
I can’t just disregard the code since I have to pass the emission test on the way to work.
I am unable to afford to experiment with components or to see a reputable mechanic due to budgetary constraints. Thank you for your assistance, your knowledge, and your advice. Best wishes and Happy Holidays to you! Aibek Mursalimov is a Russian actor.
Running Superb but still have codes P2187 + P2189
Okay, I brought it to a person (who knows what he’s doing) who gave it a once-over before returning it to me. He claims that there is a leak, but that it is not coming from the hoses. He claims that when he tested with propane all throughout, he discovered that the fuel trims were zeroed out at the rear and bottom sides of the plenum. Even though he didn’t disassemble anything, he believes that either the intake plenum gasket, the intake manifold gasket, the injector seals, or any combination of these are to blame.
– The intake plenum gasket has been replaced.
Fortunately, the gentleman who examined my automobile took the time to clarify what that meant: long-term vs short-term compensation percentages.
Now I understand what the trim numbers are referring to.
From my perspective, it seems logical to speculate that the intake plenum is responsible.
On some vehicles, such as BMWs, this can make a difference; however, I’m not sure about Kias and Hyundais.
It’s made of metal.
Victor-Reinz is the name of the metal replacement I received from Rock Auto.
According to my Haynes handbook, the plenum bolt torque should be 8 ft/lb.
Do I require more precise torque specifications?
– Fel-Pro Rubber-fiber Sheet is on hand, and it appears to be wide enough to cut an accurate copy (I’m handy with an exacto knife).
In accordance with the material sheet, it is mostly used for timing covers, fuel pumps, differential covers, and for sealing oil, water, and gasoline.
Once again, thank you for your assistance.
