The P002E fault code, applicable to all car manufacturers, means “B Camshaft Profile Control Circuit Low (Bank 2)“.
Background Information: The camshaft controls the opening and closing of the valves. In a variable valve timing system, the electronic camshaft adjusting valve (or oil control valve, OCV) adjusts the camshaft angle by changing the oil pressure to the camshaft adjuster (mechanical type) according to instructions from the engine control module (ECM), ensuring that the valves open and close at optimal times. This optimizes engine efficiency and power across all engine speeds. This fault code indicates that the voltage of the B (exhaust/right/rear) camshaft profile control circuit is below the calibrated minimum value.
Main Causes of P002E Fault Code:
- Faulty camshaft variable timing solenoid
- Low engine oil level
- Incorrect engine timing
- Engine oil not meeting manufacturer specifications
- Faulty variable valve timing actuator
- Worn timing chain
Symptoms of P002E Error Code:
- Check Engine Light (CEL) illuminated
- Reduced engine performance and power
- Poor fuel economy
- Rough idle or stalling
- Engine misfires
- Engine overheating
- Increased emissions
How to Fix P002E?
To fix the P002E fault code, which indicates a low voltage or intermittent electrical problem in the camshaft profile control circuit in Bank 2, follow these steps:
- First, ensure the engine is off and the key is removed from the ignition.
- Inspect the wiring and connections of the Bank 2 camshaft profile control circuit. Look for signs of damage, such as frayed wires or loose connections. Repair or replace any damaged or defective wiring or connections.
- If the wiring and connections are in good condition, check the camshaft position sensor in Bank 2. This sensor is responsible for providing camshaft position data to the engine control module (ECM). Ensure the sensor is securely connected and functioning correctly. Replace the sensor if necessary.
- Next, check the camshaft actuator solenoid in Bank 2. This solenoid controls the oil flow to the camshaft gear, thereby regulating the camshaft timing. Check if the solenoid is functioning correctly and replace it if there are any problems.
- After checking and repairing or replacing any faulty components, use an OBD-II scanner to clear the fault code from the ECM. This will reset the system and allow the ECM to re-evaluate the camshaft profile control circuit.
- Start the engine and monitor for the recurrence of the fault code. If the code does not reappear, the problem is likely resolved. However, if the fault code returns, further diagnosis may be needed to identify the underlying issue.
If you are unsure or uncomfortable performing these steps yourself, be sure to consult your vehicle’s repair manual or seek assistance from a professional technician.
Can I fix the P002E code myself?
Repairs typically required to fix a P002E code include:
- Replacing the engine oil and filter
- Replacing the camshaft variable timing solenoid
- Repairing or replacing the variable valve timing actuator
- Adjusting or replacing the timing chain
If you have automotive repair experience and a good understanding of engine components, you may be able to resolve issues related to the P002E code yourself. However, for most drivers, it is recommended to consult a professional technician to ensure proper diagnosis and repair.
