The P002F fault code, applicable to all car manufacturers, means “B Camshaft Profile Control Circuit High (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 higher than the calibrated maximum value.
Main Causes of P002F Fault Code:
- Lack of oil maintenance
- Incorrect engine oil
- Contaminated oil
- Faulty oil control valve
- Stuck valve
- Broken wire
- Electrical short circuit (internal or mechanical short)
- ECM (Engine Control Module) problem
Symptoms of P002F Error Code:
- Low power
- Poor driving performance
- Reduced fuel economy
- Abnormal throttle response
- General decrease in efficiency
- Changes in power band
How to Fix P002F?
- First, use an OBD diagnostic tool to scan for the specific cause of the code to determine the problem.
- Check the camshaft position sensor, wiring, and connectors for damage or corrosion. Replace or repair as needed.
- Test the ECM to ensure it is functioning correctly; replace if faulty.
- Check the camshaft and camshaft phaser for mechanical problems, such as wear or damage, and replace if necessary.
- Check the engine oil level and quality, and address any issues that may affect VVT operation.
If you are unsure or uncomfortable performing these steps yourself, be sure to consult your vehicle’s repair manual or seek the help of a professional technician.
