P052A OBD Error Code: Problem & Solutions

<<See All OBD Codes

The error code P052A can be defined as Cold Start A Camshaft Position Timing Over-Advanced Bank 1.

 

The P052A code would alert the operator that the ECM has monitored an "overly"- advanced VVT position for camshaft timing on bank 1. This can be generally due to cold start up. The failure of this VVT self-test stems from the exceeded maximum calibration of the camshaft timing or it remains in an advanced position. Bank 1 is the side of the engine which has the #1 cylinder.

Want to learn something more about the P052A error code? The variable camshaft timing position for an over-advanced camshaft timing is monitored by the powertrain control module during cold start up. If the camshaft timing will exceed a maximum calibrated value or might remain in an advanced position, then the test would fail.

 

What causes this problem with the Cold Start A Camshaft Position Timing Over-Advanced Bank 1?

 

• Some flaws in the intake valve timing control solenoid valve
• Quirks in the intake valve timing intermediate lock control solenoid valve
• The crankshaft position sensor might be faulty
• Defective camshaft position sensor
• The signal pick-up portion of the camshaft has accumulated debris
• The timing chain might be incorrectly installed
• Foreign matter may contaminate the oil groove for intake valve timing control

1. Electronic Control Unit - Did your mechanic just found out that there is some fault in the fuel Electronic Control Unit? Buy top notch Electronic Control Unit from us at economical prices.
2. Timing Chain - A broken Timing Chain can cause a lot of issues. It would be nice if you get it replaced on time.
3. Air Intake System Parts - Everything is fine with the engine control module and still OBD code P052A flashing? Then there is definitely some fault with the Air Intake System Parts. Get it checked and replace if needed.
4. Throttle Body - Throttle Body is an important car part which should never be neglected. May be there is some fault in it due to which P052A code may start flashing.
5. Camshaft Position Sensor - A faulty Camshaft Position Sensor can be troublesome. You can always rely on us as we have best auto parts for our customers.
6. Crankshaft Position Sensor - If everything is alright with PCM, then there is surely some defect in Crankshaft Position Sensor. Get it replaced before the situation gets worse.
7. Throttle Position Sensor - P052A code can display due to some issues in the Throttle Position Sensor. So, it is very important to replace the Throttle Position Sensor with us at equitable prices.

Our main motive is to achieve customer satisfaction as for us our customers are everything and that’s why we will help you to diagnose P052A code by mentioning some major symptoms below:

 

Common Symptoms

 

• Bad engine performance
• Diminishing fuel economy
• There can be possible misfire on start-up
• Some cold start issues

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 P052A:

 

• Replace the faulty camshaft position sensor
• Correct the flaws in the intake valve timing control solenoid valve
• If there are some defects in the crankshaft position sensor, then it should be replaced
• Restore the intake valve timing intermediate lock control solenoid valve
• Foreign matter may contaminate the oil groove for intake valve timing control. So, it should be corrected
• You must install the timing chain correctly

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

 

Initial step in the troubleshooting process for any malfunction is to research the Technical Service Bulletins for known issues with the specific vehicle. 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 centre 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 misdiagnosis. 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 reluctant 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

 

Be very careful when disconnecting any injector connector, during diagnosing. Like mentioned, they tend to be extremely brittle.
