P054C - OBD Trouble Code

<<See All OBD Codes

This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

The P054C error code can be described as Cold Start B Camshaft Position Timing Over-Advanced Bank 2.

It is the engine control module which manages and monitors the vehicle's engine ignition system, mechanical positioning of the rotating assemblies, fuel injection, emission systems, exhaust, transmission, among countless other systems. One another system which the engine control module monitors as well as adjusts is the variable valve timing system. This system would allow the ECM to monitor the mechanical timing between the camshaft and the crankshaft. The general efficiency in the operation of the engine would then be increased. At the same time there would be a benefit in the fuel economy. The engine's ideal timing would keep on adjusting as per the situations. That is the reason why the VVT system has been designed.

What causes this problem with the Cold Start B Camshaft Position Timing Over-Advanced Bank 2?

• Flaws in the intake valve timing control solenoid valve
• The intake valve timing intermediate lock control solenoid valve is flawed
• The timing chain might not be properly installed
• The crankshaft position sensor might be defective
• Defects in the camshaft position sensor
• Foreign matter may contaminate the oil groove for intake valve timing control
• Accumulated debris in the signal pick-up portion of the camshaft

1. Camshaft Position Sensor - Do you remember when was the last time you got your car Camshaft Position Sensor checked up? A dirty Camshaft Position Sensor can cause a lot of issues like displaying P054C code.
2. Cylinder Head Gasket - Poor Cylinder Head Gasket can cause a lot of difficulties, so why not get it replaced at time?
3. Crankshaft Position Sensor - Are there some faults in your Crankshaft Position Sensor? Don’t waste time and get them replaced or else P054C code can turn up.
4. Powertrain Control Module - OBD Code P054C can appear because of faulty Powertrain Control Module.
5. Engine Wiring Connectors - Everything is fine with Powertrain Control Module and still P054C code triggering? Then you must get your Engine Wiring Connectors checked.
6. Fuel Injection System Parts - There can be some issues with the Fuel Injection System Parts due to which you may see P054C code appearing over and over again. Visit us to buy best quality Fuel Injection System Parts online.
7. Engine Control Module - A lot of issues can arise do to defective Engine Control Module. Did you just see P054C code flashing? Now you know the reason why it is appearing. Get it inspected and replaced on time.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P054C code by mentioning some major symptoms below:

Common Symptoms

• Fuel economy might start diminishing
• There can be a misfire on start-up
• Some cold start issues
• Decrease in the engine performance

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P054C:

• If you find out that there are some faults in the camshaft position sensor, then it should be repaired or replaced as per the need
• Restore the faulty intake valve timing control solenoid valve
• Replace the defective crankshaft position sensor
• The intake valve timing intermediate lock control solenoid valve should be replaced
• The timing chain should be installed properly

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of car oil filter, k&n filter, timing chain replacement, diesel injection, ac delco oil filter, hydraulic filter and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this fault code:

Research the technical service bulletins for known issues with the specific vehicle during troubleshooting process for any malfunction. Advanced diagnostic steps become very vehicle specific and may require the appropriate advanced equipment and knowledge to perform accurately. We include basic steps below but refer to a vehicle year/make/model/powertrain specific repair guide for specific steps for your vehicle. Make sure that you check for any Technical Service Bulletins that could provide possible solutions for any problems since most vehicles have upgradeable software in their ECMs. If a replacement is required, it is best to use a brand-new factory ECM and to program the latest software. This step will require you to take a trip to an authorized service center of the brand of your vehicle

Just remember that an ECM can easily be replaced when there was actually a defective engine sensor, which can be a result of an overlooked detail in the initial diagnosis. This is the reason why professional technicians will follow some sort of flow chart when inspecting a trouble code to prevent a misdiagnoses. It's always a good idea to refer to your specific model's service information first

It would be a good idea to test the camshaft leaks immediately as they can produce more issues down the road if left unattended. Refer to your service manual for specific diagnostic procedures as well as location of the components. Depending on what type of camshaft position sensor you have (e.g. Hall effect, Variable reluctance sensor, etc.), diagnostics will vary as per the make and model. There should be power present at the sensor in order to monitor the shafts position. If found defective, replace the sensor, reset the codes, and then test drive the vehicle. Given the fact that "cold start" is in the description of the code, you should probably take a look at your cold start injector. It also, may be mounted to the cylinder head and somewhat accessible. Injector harness' are extremely susceptible to drying up and cracking, due to conditions, causing an intermittent connection. And most likely a cold start issues as well. Just very careful when you are disconnecting any injector connector, during the process of diagnosis

Common Mistakes When Diagnosing The P054C Code

• The engine oil does not meet the manufacturer's requirements
• Variable valve timing actuator might be defective
• The oil level of the might be too low
• Powertrain control module might start failing
• Defects in the variable valve timing solenoid
