- Code P0332 Definition Knock Sensor 2 Low Circuit Input (Bank 2) What Does P0332 Mean? Knock sensors are solely used for the purpose of sensing when your engine is “knocking,” or sensing when there is exploding in the air/fuel mixture in a way that delivers less power and can also damage the engine if prolonged.
How do I fix error code P0332?
What repairs can fix the P0332 code?
- Replacing frayed or broken wires and connectors in the sensor circuit.
- Ensuring that the sensor and circuit are properly grounded.
- Replacing the knock sensor.
- Addressing the root cause in the EGR or cooling system.
- Replacing or reprogramming the PCM (rare)
What is a circuit Low Bank 2?
Diagnostic trouble code (DTC) P0332 stands for “ Knock Sensor 2 Circuit Low Input (Bank 2).” It belongs to a range of trouble codes that are triggered by a knock sensor malfunction (P0325 to P0334). Without proper readings from the knock sensor, the PCM cannot accurately alter ignition timing to prevent engine knocking.
What causes low voltage on knock sensor?
What Does the P0327 Code Mean? Diagnostic trouble code (DTC) P0327 stands for “Knock Sensor 1 Circuit Low Input (Bank 1 or Single Sensor).” It is triggered when the powertrain control module (PCM) detects very low voltage readings from your vehicle’s primary knock sensor circuit.
What causes a knock sensor code P0332?
When the engine “knocks” there is an excessive amount of NOx that is released. When trouble code P0332 is set, the Power Control Module (PCM) has received a reading from knock sensor 2 in Bank 2 that is too low, and it will not be able to accurately send a ping to correct a problem.
Can you drive with a bad knock sensor?
In conclusion, you can drive with a bad knock sensor —that is, if you want to destroy your engine and get atrocious performance from your car. The moment you confirm that your knock sensor has seen better days, it would be wise to swap it right away with a high-quality replacement.
Can bad gas cause knock sensor code?
a knock sensor is used to detect engine knocking or pinging, which results from abnormal combustion in the engine cylinders. if left unchecked, this bad combustion could ruin parts of your engine. engine knock can also be cause by bad fuel, so if you hear it, try getting better gas next time.
Is a P0332 code bad?
While all engine codes can be serious, most times, a code P0332 is not a serious condition. Usually, the worst thing that happens with a code P0332 is that engine emissions will increase, which means you won’t pass an emissions test. However, if an underlying engine knock occurs, you won’t have a sensor to detect it.
What is a knock sensor 2 Circuit Bank 2?
The knock sensor monitors engine “knock”—this indicates that the engine is experiencing unusual combustion in the form of detonation or pre-ignition. Code P0330 may be set when your PCM detects a problem with the #2 knock sensor or its circuit. The knock sensor is usually bolted or threaded into the engine block.
What code is P0174?
Diagnostic trouble code (DTC) P0174 stands for “ System Too Lean (Bank 2).” The code indicates that your car’s computer has detected a lean running condition.
Can a bad battery cause a knock sensor code?
Can a bad battery cause a knock sensor code? A sinking, fading car battery indicates low voltage. As a result, your vehicle computer, liable for notifying error codes and also getting low voltage. An error code will be created, triggering the check engine light or even the battery change warning light to reveal.
What problems can a knock sensor cause?
The pinging can cause severe issues like blowing holes on the Piston or even cause the combustion process to burn. If a knock sensor goes completely bad, you’ll experience loss of fuel mileage, hesitation, and reduced power.
Does a knock sensor affect performance?
A faulty knock sensor can also cause the PCM to misadjust the ignition timing, resulting in poor engine performance. The knock sensor is typically screwed into the engine block or manifold.
How much does it cost to replace a knock sensor?
On average, you should pay between $280 and $350 for a knock sensor replacement. For the labor, expect to pay $220 to $280. Parts should only be about $65-$75.
Why do I need a knock sensor?
Knock sensors are vital to the function of your car because they prevent your engine from being damaged due to too much air pressure caused by the air and fuel mixture mentioned above. When the engine does experience extensive damage, your car will break down.
How do you fix a knock sensor?
Remove the knock sensor and discard it. Smear dielectric grease onto the threads of the new sensor. Screw the sensor in by hand as far as it will go. Tighten it firmly with the wrench.
OBD-II Trouble Code: P0332 Knock Sensor 2 Circuit Low Input (Bank 2)
Knock Sensor 2 Circuit has a low input voltage (Bank 2)
What does that mean?
This diagnostic trouble code (DTC) is a general powertrain code, which means that it applies to any cars that are equipped with the OBD-II diagnostic system. Despite the fact that they are general, the particular repair processes may differ based on the make and model. In the event that one or more of your engine’s cylinders are “knocking,” the engine computer is notified. Knocking is defined as bursting the air/fuel mixture in a way that results in less power and may be harmful to the engine if it occurs for a lengthy period of time.
If your knock sensor on Bank2 is providing a low output voltage (for example, less than 0.5V), it will cause a P0332 DTC to be set on your computer.
P0325, P0326, P0327, P0328, P0329, P0330, P0331, P0333, and P0334 are some of the other knock sensor-related DTC codes that can be seen.
Driveability issues such as fluctuating engine RPM, lack of power, and even some hesitation may be noticed when driving your vehicle. There might also be other signs and symptoms.

These “Knock Sensor Circuit Low Input”OBD2codes are explained by our mechanic in this video, as well as the causes of these codes and how to troubleshoot your car’s knock sensors by analyzing their signals and checking their wire harnesses. Now is a good time to watch:
Check Engine Light? Knock Sensor Low Input – Code P0327 P0332
“Knock Sensor 1 Circuit Low Input (Bank 1),” and “Knock Sensor 1 Circuit Low Input (Bank 2),” are two codes that indicate that your knock sensors are bad—that they’re not working properly—and that you should get them replaced.
What is engine knock?
It is possible for an internal explosion to occur during a vehicle’s combustion process, which you can read about in ” How to diagnose a misfire: Expert help from our mechanics,” if a spark plug ignites its gasoline too early or if the fuel used in the vehicle is incorrect. This can result in an internal explosion that occurs outside of the normal combustion process. The knocking or tapping sound produced by this engine knock is a knocking or tapping sound. Essentially, the objective of knock sensors is to monitor engine banging and send a warning to your car’s computer, also known as the powertrain control module (PCM).
How serious is engine knocking and error codes P0327 and P0332?
Engine knocking may cause serious damage to your engine and result in more expensive repairs if left untreated, therefore it’s better to handle a P0327 or P0332 as soon as possible and avoid driving while the problem is present.
What are typical P0327 and P0332 code symptoms?
- Your Check Engine light is illuminated
- Aspects of driveability that might be problematic include difficulties in accelerating and maintaining constant RPM, as well as engine power loss. Sound of someone banging or tapping on something
What causes a P0327 or P0332 code?
- A malfunctioning or defective knock sensor
- Knock sensor circuit wire that is faulty, open, or shorted
- Knock sensor wire connection that has corroded
How do I diagnose and fix P0327 or P0332?
For example, our technician works on a car that has knock sensors that are positioned under the intake, thus he has remove the intake in order to access them in the video above.
Test your knock sensors’ data readings
- Placing one of the leads on one of the knock sensors and connecting the other lead to ground while the meter is set to AC voltage for the millivolts range is the next step. Using a screwdriver, tap near the sensors, keeping an eye on the meter reading as you go
- While doing this, if the values do not change at all, it is likely that the problem which is triggering a P0327 or 332 is an open circuit in the knock sensor. A multimeter may also be used to measure the resistance of the knock sensor (2:19). Make sure that your meter is set to ohms (which looks like a little horseshoe), and that one of your lines is placed in the ground and another one on one of your knock sensors. If your meter’s readout indicates “OL,” this indicates that there is an open circuit in one of the sensors, which suggests that the knock sensor is not functioning.
Check your knock sensor wire connectors for corrosion
- It will be necessary to replace both the sensor and the wire if the knock sensor connector becomes corroded.
- The wire harness should be changed at the same time as other items in this region, such as a defective knock sensor that requires replacement, according to our expert after evaluating the knock sensors. It is not necessary to replace wiring harnesses because they are not expensive components
- Nonetheless, they grow brittle with time and should be replaced.
A word of caution while changing knock sensors: they are quite sensitive, and you don’t want to unintentionally drop them and cause harm.
How to Replace Knock Sensors
Once you’ve established what caused a P0327 or P0332 code to appear in your vehicle and replaced any defective parts, clear the code and test drive the vehicle to ensure that everything is working properly.

P0332 OBD2 Code: Knock Sensor 2 Circuit Low Input (Bank 2)
It is necessary to activate the P0332 Code when the bank 2 knock sensor fails to provide a signal to the engine computer. It is necessary to activate the P0332OBD2 code when the bank 2 knock sensor is not transmitting a signal to the engine computer. This sensor is your engine’s first line of defense against knocking, which is a very dangerous condition that may cause major engine damage if left unattended for an extended period of time. P0332 is a serious error code that should not be taken lightly.
You’ll notice greater pollutants and decreased fuel economy, which are issues that you’ll want to address as soon as possible.
While P0332 is frequently caused by problems with the knock sensor or its surrounding circuitry, it can also be caused by problems with other engine components. The usage of other codes that show up can help you narrow down your diagnosis and pinpoint the true source of your problem.
P0332 Code Definition
When the bank 2 knock sensor fails to deliver a signal to the engine computer, the P0332 code is activated, and the engine computer is informed. When the bank 2 knock sensor fails to provide a signal to the engine computer, the P0332OBD2 code is activated. The knock sensor is your engine’s first line of defense against knocking, which is a major condition that, if left unaddressed, can result in catastrophic engine damage. When you see the code P0332, don’t take it too lightly! A P0332 problem code indicates that the engine is running poorly.
When you scan your vehicle, pay close attention to all of the codes you see.
You can utilize any additional codes that appear to aid your diagnosis and uncover the true source of your problem.
What does P0332 mean?
In engines, knocking or pinging are terms used to describe the process by which the air/fuel combination in the engine explodes. When this occurs, less power is given to your engine, and more dangerous pollutants are released into the atmosphere through your exhaust system. The interior components of a vehicle can be seriously damaged by prolonged banging. The knock sensors on your engine are designed to alert you if your engine is knocking, which may be dangerous. Powertrain control module (PCM) or engine control module (ECM) readings are monitored by the powertrain control module (PCM) or engine control module (ECM), which is responsible for both detecting knocks and ensuring that the sensors are performing correctly.
When this occurs, the engine computer is unable to communicate properly with the knocking sensor, making it unable to identify knocking issues.
The P0332 OBD2 code is related to your engine’s second knock sensor, which is located on bank 2 of the engine.
In certain cases, this code will appear alongside other knock sensor DTCs, such as the P0325-P0334 codes.
What are the symptoms of the P0332 code?
It is possible that you will not experience any drivability symptoms when the P0332 fault code is displayed. You’ll most likely notice one or more of the symptoms listed below, however, the majority of the time.
- Increased hazardous emissions
- Pinging or banging of the engine during acceleration
- Engine running at a higher temperature than usual
- Reduced engine power and efficiency
- Engine operating at a higher temperature than normal
- Inconsistent engine RPM readings
- Hesitation with the engine when accelerating
What are the causes of P0332?
- Knock sensor that is not working properly
- An open or short in the knock sensor circuit
- Damaged or defective wiring in the vicinity of the knock sensor
- The air/fuel mixture is far too lean. Deficiencies in the cooling system Exhaust gas recirculation (EGR) system failure due to faulty components PCM or ECM that is not operating properly (this is less common)
How serious is the P0332 code?
The P0332 error code is an extremely significant problem. In order to prevent long-term damage to your engine, it’s critical that your engine computer be able to identify and respond to knocking signals and other abnormalities. If you’re suffering drivability concerns, you should pull over and get the problem fixed as soon as possible.
How to diagnose and fix the P0332 code
You’ll need the following tools:
- To read all of the codes from your vehicle, you’ll need to use an OBD2 scan tool. If any other codes are displayed along with this code, make a note of them. In particular, make a note of any codes that suggest a lean air/fuel mixture, problems with the EGR system, or problems with the cooling system. Clear any codes from your car and put it through its paces, then re-scan to see whether P0332 reappears. Take a look at the freeze frame data from the time that the problem occurred. As a result of the knock sensor providing a signal to the PCM, it is possible that the engine is getting inaccurate data regarding coolant temperature. In particular, if your engine has been operating at a higher temperature than usual, this is a possible culprit. Use a digital multimeter to check the coolant temperature sensor, obtaining readings both when the car is first started and after it has been allowed to idle until it reaches operating temperature. Examine the results in relation to the specifications listed in your handbook. If the sensor needs to be replaced, do so. This means that if the knock sensor is not transmitting any signals to the PCM or ECM, it is possible that there is an issue with either the knock sensor or the wiring. Examine the cables that surround the knock sensor, paying special attention to the ends, which may be frayed or otherwise damaged. Inspect any cables for damage or incorrect connections, and make sure all connections are secure
- Check to see that the knock sensor is receiving the right voltage from the engine and to see if there are any shorts or openings to the ground on the circuit. Once again, use an OBD2 scanner to double-check the data from the knock sensor. If the sensor is still not transmitting a signal, the sensor itself is most likely the source of the problem. When you test the knock sensor’s resistance, be sure that it matches the requirements in your service manual. If the tests reveal that the knock sensor is malfunctioning, it should be replaced. This is something that you should discuss with a mechanic before attempting it. In the event of P0332 codes, it is frequently suggested to replace the whole wire harness as well as the knock sensor. It is possible that you have a more significant problem with your engine computer if the P0332 error persists after replacing the knock sensor. Discuss your options with a mechanic to figure out what to do next
Common mistakes to avoid while diagnosing the P0332 code
When a P0332 DTC is displayed, some unskilled technicians may instantly replace the knock sensor with another.
The problem, on the other hand, is frequently with the wiring, and it can be caused by defects in other systems as well. Before changing any components, be certain that you have performed a complete diagnosis.
Tips to avoid P0332 in the future
The P0332 diagnostic issue code, as well as a slew of other diagnostic trouble codes, is frequently caused by wiring problems. A visual check of your engine’s wiring should be performed as part of your normal maintenance routine to ensure that no damage has been done by heat from neighboring components or that no wires have been jostled free by engine vibrations.

I got a CEL – P0332 knock sensor 2 circuit low bank 2
I had a situation that was comparable to yours. The intake gaskets were replaced, and the plugs were cleaned. Because the coils were not changed, the error codes 301, 303, 305, and so on are misfire codes. As part of a blanket change out, the garage has changed plugs and coils at a significant expense to you. The misfires will be reported if the knock sensor becomes defective. The bad news is that replacing the knock sensor is a time-consuming process that requires removing the air track bulge on the top of the engine, removing the injector rail and lower mounting that holds the injectors, and removing the knock sensor.
At this point, you can only see the knock sensor; however, you must remove the aluminum pipe and the steel pipe that leads to the water pump first.
The knock sensor is secured in place by a single bolt and is connected to the engine via a black cable that terminates at the waterpump end of the engine and plugs into the engine loom.
It is less expensive to ship it to the United Kingdom for repair at the fees you have been quoted.
P0332 Knock Sensor 2 Circuit Low Input (Bank 2) code HELP
- The same thing happened to me once. The inlet gaskets were replaced, and the plugs were thoroughly cleaned
- Despite the fact that the coils have not been replaced, the error codes 301, 303, 305, and so forth are misfire codes. In order to do a blanket change out, the garage has changed the plugs and coils at a significant expense to you. The misfires will be reported if the knock sensor is malfunctioning. Sadly, changing the knock sensor is a time-consuming process that requires removing the air track bulge on the top of the engine, removing the injector rail and lower mounting that supports the injectors, and removing the knock sensor itself. Using a paper towel, cover the intake holes to prevent anything from falling through. Only the knock sensor is visible right now, but you must first remove the aluminum tubing and steel pipe that connects it to the water pump before you can continue. Unscrewing one of the bolts will necessitate the use of a 10mm ring spanner with a 90° bend in it. With only a single bolt holding it in place, the knock sensor is connected to the engine’s waterpump end by a black wire that plugs into the engine loom. If you mail it to the UK for repair at the costs you have been quoted, the knock sensor will cost around $30 and will take approximately 5 hours to remove and replace.

P0332 OBD-II-foutcode: Klopsensor 2 Circuit Low Input (Bank 2) – artikelen – 2022
Artikelen2022P0332-codedefinitie When the knock-sensor 2-schakeling detects a weak ingangssignal, the PCM (aandrijflijnbesturingsmodule) registers a P0332-code, which indicates that the sensor is malfunctioning.
When the knock-sensor 2-schakeling detects a weak inflow signal, the PCM (aandrijflijnbesturingsmodule) registers the P0332 code and illuminates the Check Engine Light.
Wat de P0332-code betekent
The purpose of the ping-sensor is to send a signal to the PCM whenever the motor makes a pinging sound. When the PCM receives a ping signal from a pingelsensor that is too far away, the resulting ping signal will not be accurate, and the PCM will be unable to resolve the problem. This can also result in higher emissions and other problems for the engine.
Wat veroorzaakt de P0332-code?
When a P0332 code is generated, the following are the most common reasons for it to be generated:
- A pingelsensor that is not working properly
- Uncorrected error in the knock-sensor circuit of the connections. An air/brandstof relationship that is too strong
- There is a problem with the koelsysteem
- A malfunctioning EGR system (upstream gas recirculation)
Wat zijn de symptomen van de P0332-code?
In certain extreme cases, there will be no other symptom present but the controlelampje that activates the oplighting system. Most of the time, you will notice one or more of the following symptoms:
- Pings in the motor when the vehicle is being driven
- Increased motor temperature under regular operation
- A rebuke or a reversal of a mistake
Hoe diagnosticeert een monteur de P0332-code?
After the code has been verified with an OBD-II scanner, the installer begins by visually inspecting the sensor and the circuit. They will next use an ohmmeter and other diagnostic tools to check the circuit, the connectors, and any other components that are connected to it, as well as the rest of the system. Following each test and / or repair, the code from the PCM is extracted and the system is tested once more by inserting the voertuig into the vehicle’s transmission.
A brief or in-depth testrit may be performed in some instances, in order to verify whether or not there is an intermittent problem that requires attention.
Veelgemaakte fouten bij het diagnosticeren van de P0332-code
Some of the most frequently encountered errors in this code have to do with the inability to properly inspect and diagnose the underlying cause of the problem in question. Occasionally, a pingelsensor is replaced when the problem was due to the bedrading or connectors, rather than the pingelsensor itself. In other cases, the problem may be with the koelsysteem or the EGR system, in which case the replacement of the pingelsensor will have no effect on resolving the problem.
Hoe serieus is de P0332-code?
Engine pinging can have a negative influence on the ability of an engine to operate efficiently and reliably in certain situations. When the pingelsensor does not operate properly, the PCM is unable to obtain the necessary information in order to diagnose and correct the problem. A result of this might be a motor that runs on the ruw, has excessive wear, reduces brand efficiency, and has other issues as a result of this.
Welke reparaties kunnen de P0332-code repareren?
