P3497 Cylinder Deactivation System Bank 2

ByStephen DarbyASE Certified TechnicianCylinder Deactivation System Bank 2 is the subject of this article.

What does that mean?

This generic powertrain diagnostic problem code (DTC) is commonly seen in a large number of OBD-II automobiles and is described as follows: This may include, but is not limited to, automobiles from Honda, Dodge, Ram, GMC, Chevrolet, Chrysler, Pontiac, and other manufacturers, as well as other makes. A stored code P3497 indicates that the powertrain control module (PCM) has identified an issue in the cylinder deactivation system for engine bank 2 and has reported it to the driver. Bank two refers to the bank of the engine that does not contain the 1st cylinder of the engine.

Consult your service manual (or another source of vehicle information) to determine the position of the number one cylinder in the vehicle in issue; never make assumptions about the placement of the number one cylinder in any vehicle.

Most of the time, they are seen in cars that are equipped with engines that have eight or more pistons.
Low throttle and motorway speeds are common driving conditions under these circumstances.
When a cylinder is deactivated, variable valve timing solenoids are used to close the intake and exhaust valves for that cylinder, which is a good thing.
As a result, vibration is reduced, and the cylinder deactivation function is smoother.
The compressed exhaust is responsible for propelling the piston back downward and ensuring an even greater degree of overall engine balance.
Most of the time, there is no discernible reduction of power or torque when the cylinder deactivation mechanism is turned on or activated.
Engine for deactivating cylinders:

What is the severity of this DTC?

Beyond the fact that cylinder deactivation difficulties might reduce fuel economy, the various causes of cylinder deactivation problems can result in catastrophic engine failure.

Possible Causes: This mistake can be produced by a variety of factors, the most frequent of which is a malfunctioning oil pressure sensor. P3400 is the Engine Error Code.

If you require a visual walk-through, there is one at the bottom of the page. An Engine OBDII Error Code P3400 is defined as follows: It is a Cylinder Deactivation System Bank 1 on a Honda that has an Error Code P3400. Possible Causes: This mistake can be caused by a variety of factors, the most frequent of which is a faulty oil pressure sensor. The error code P3400 is associated with the engine.

A faulty oil pressure switch sensor is frequently the cause of a P3400 error code in a Honda. While this is a typical reason for Error Code P3400 to occur, it is not the only reason for this to occur. Oil pressure switch sensors are frequently changed initially since they are a common source of failure and are a low-cost component. On Amazon, for example, you may find a Honda Oil Pressure Switch. Beck Arnley 201-1649 Oil Pressure Switch with Light is a high-quality oil pressure switch. Identifying and Correcting the Honda Engine Error Code P3400 (Replace Oil Pressure Sensor)

It is not visible from the outside. It will be connected to a wire plug harness, which will need to be removed in order to be removed. It will require the use of a 24 mm Deep Socket in order to be removed. After removing the old sensor, replace it with the new one, making sure that it is well sealed so that oil does not leak.

Summary Repairing a P3400 is typically straightforward and comes into the category of do-it-yourself projects for the home mechanic. If in doubt, it’s always best to consult with a specialist. Because certain vehicles are simpler to work on than others, it is important to know the brand and model of the car you are working on.

P3400: Cylinder Deactivation System Bank 1

Do you have any idea why your check engine light is on? Diagnoseing the problem with a car might seem like an impossible effort for many individuals. Fortunately, most modern automobiles are constructed with a system of codes that makes it much simpler to diagnose problems. Mechanics utilize unique equipment that interact with the automobile and get a specific code that relates to the specific problem that the car is experiencing. Anyone, on the other hand, can make use of one of these gadgets.

The cylinder deactivation mechanism is the source of the OBD-II scanner error code P3400 issue.

What Does P3400Mean?

The notion of a cylinder deactivation mechanism that isn’t working properly is a little difficult to grasp. So, what exactly does the code P3400 represent? You’re undoubtedly aware that the cylinders of an engine are the parts of the engine that really produce power. Having all of the cylinders spinning signifies that the engine is operating at maximum capacity. The majority of automobiles are equipped with four cylinders, however several are equipped with six or eight. If a vehicle has more than one cylinder, it may be equipped with a cylinder deactivation mechanism.

In situations where your automobile is simply traveling or has a low throttle, four cylinders will suffice to complete the task at hand.

This mechanism inhibits some of the cylinders from igniting, which helps you save money on gas and preserves the environment. The cylinder deactivation mechanism works in two ways: first, it deactivates the cylinder.

To be more specific, the cylinder deactivation system shutters the intake and exhaust valves for the cylinders that are no longer required. Because relatively minor explosions occur inside the cylinders, it is critical that the valves are correctly closed. It is a very sensitive and extremely strong piece of machinery. The process of disabling fuel flow is simpler and easy to comprehend. The entire purpose of deactivating the cylinders is to improve fuel economy, which can only be accomplished by stopping the flow of gasoline to the cylinders.

What Are TheSymptoms of P3400?

Symptoms connected with this error code are few, and the majority of them are minor in nature. It should illuminate your check engine light if the cylinder deactivation system cannot be activated, or if it activates when it is not meant to. In all likelihood, this will be the most significant indication that anything is wrong with you. However, you may be able to determine if the cylinder deactivation mechanism is faulty if you see any of the following symptoms:

A reduction in fuel economy
A reduction in power
A reduction in engine performance.

Let us now turn our attention to the most pressing question: ‘How can I resolve issue code P3400?’ Reduced oil level or pressure is the most prevalent cause of this issue. First and foremost, check your oil levels and add additional oil if necessary. If it does not resolve the problem, you should have a manual oil pressure test performed. After that, you can try to drive the car to check whether the error code shows again. If this is the case, the problem is very certainly due to a broken or malfunctioning part.

Do not attempt to repair these components unless you are quite confident in your ability to delve into your engine.

What HappensIf You Ignore P3400?

When the cylinder deactivation mechanism fails, there is only a very small risk of serious injury or death. It will only have a negative impact on fuel economy. It should be noted, however, that the most typical reasons of this system failure can also result in highly catastrophic engine difficulties. If these are left unchecked, your entire engine might fail, resulting in serious injury or the need for expensive repairs.

This warning relates to the Honda Accord V6 models from 2008 to 2012 that are equipped with automatic gearbox. It is necessary to check the engine oil level if DTC P3400 (VPS stuck off bank 1) and/or P3497 (VPS stuck off bank 2) are set, since insufficient oil pressure might cause these codes to be activated. If the oil level is low, make any necessary adjustments or replacements. Check that the oil level is enough, then clear the DTC(s) and flip the ignition switch to the ON position without turning on the engine (key on, engine off).

If you have DTC P3400, unplug the rear rocker arm oil pressure switch 1P connector.
Go to the PGM-Fl Data List and look for the signal from the rocker arm oil pressure switch.
Replace the oil pressure switch with a new one.
If the switch signal indicates that the vehicle is running, there is an issue with the wiring or the PCM.
If the DTC(s) do not clear, restart the engine and allow it to idle for one minute before continuing.

If the DTC(s) come back on, it means that the rocker arm oil control valve is leaking or has become jammed. The rear rocker arm oil control valve should be replaced if you have DTC P3400, and the front rocker arm oil control valve should be replaced if you have DTC P3497.

P3400 08 Odyssey issue

Baseball: Excellent post; thank you, thank you, thank you; you have probably saved me a lot of time and aggravation at the auto shop. For anyone who stumbles across this thread and is experiencing the same issue as I was, here are my two cents on what I tried and a couple of questions: As soon as the P3400 code appeared on my 2008 Ody, I took it to a parts store where they would retrieve the code for free, then went on Google and discovered the wonderful information above, as well as service bulletin 11-033, which I followed to its conclusion.

The oil level was a quart low, so a good lesson here is that if you have an Ody with VCM (EX-L or Touring, I believe) and the engine light comes on, check your oil level right away (5w20).

I finished it off by calling a couple Honda shops to see what they would charge for the software update (prices ranged from $70-$140), took the service bulletin and the above post with me, explained exactly what I wanted, and had the software update completed and out the door in under an hour for $70 dollars (I was pleased).

If you pay close attention to the update, you will notice a very minor detectable difference.

After about 1k miles, the code appeared again; I checked the oil and it was perfect this time; there had been no burning of a drop; I took it to the part store, where the code appeared again; I cleared the code (I guess they aren’t supposed to do that, so make a friend; my new friend’s name is Cole.

If there was a genuine problem, the light would have come back on, wouldn’t it?
When I consider what may have prompted it, I recall that the second time the code appeared, I saw it after being in a driving scenario where I would have had to slam on the brakes or step on the throttle.
It got me wondering since the first time it turned on, I saw it while I was parking at work and remembered that there was a yellow light (or more accurately, a very dark orange light, not quite red light) on the way to work and that I had chosen the gas over the brakes on that journey.
It has been around 200 miles since the code was cleared, and there have been no difficulties, no oil use, and the VCM is functioning correctly.
