P002F Fault Code

P002F OBD-II Trouble Code Short Description

B Camshaft Profile Control Circuit High Bank 2

What does trouble code P002F mean?

The P002F fault code indicates a problem with the B camshaft profile control circuit on bank 2 of the engine. This fault code is typically found in vehicles with variable valve timing (VVT) systems.

The camshaft profile control circuit is responsible for adjusting the timing of the camshaft to optimize engine performance and fuel economy. When the circuit voltage is detected to be higher than normal, the P002F code is triggered.

There are several possible causes for this fault code, including a faulty camshaft position sensor, a malfunctioning VVT solenoid, a wiring issue, or a problem with the engine control module (ECM). It is important to note that the specific cause may vary depending on the make and model of the vehicle.

To resolve the P002F fault code, the following steps may be taken:

  1. Check the camshaft position sensor: The sensor may be tested for proper functionality and replaced if necessary. This sensor is responsible for detecting the position of the camshaft.

  2. Inspect the VVT solenoid: The VVT solenoid controls the oil flow to the camshaft actuator, allowing for the adjustment of camshaft timing. It should be examined for any obstructions or signs of damage. If found faulty, it should be replaced.

  3. Inspect the wiring: The wiring harness connecting the camshaft position sensor, VVT solenoid, and ECM should be checked for any damage, loose connections, or corrosion. Any issues should be repaired or replaced accordingly.

  4. Test the ECM: If all other components appear to be in working order, the ECM may need to be tested for any internal faults or software issues. In some cases, reprogramming or replacing the ECM may be necessary.

It is recommended to consult with a professional mechanic or refer to the vehicle's service manual for specific diagnostic and repair procedures related to the P002F fault code. They will have the necessary knowledge and tools to accurately identify and resolve the issue.


What are the symptoms of the P002F code?

  • Check engine light may illuminate
  • Decreased engine performance
  • Rough idling or stalling
  • Poor fuel efficiency
  • Difficulty starting the engine


What causes the P002F code?

The P002F fault code typically indicates an issue with the B camshaft profile control circuit being detected as too high in bank 2 of the engine. Some possible causes for this fault code include:

  1. Faulty camshaft position sensor: The camshaft position sensor may be malfunctioning or sending incorrect signals to the engine control module (ECM).

  2. Faulty camshaft actuator: The camshaft actuator responsible for controlling the camshaft profile may be faulty or stuck in a high position, causing the circuit to read as too high.

  3. Wiring issues: There may be a problem with the wiring or connectors associated with the camshaft position sensor or camshaft actuator, such as shorts, opens, or poor connections.

  4. ECM malfunction: The ECM itself may have a fault or issue that is causing incorrect readings from the camshaft profile control circuit.

  5. Timing chain or belt issues: A stretched or misaligned timing chain or belt can cause issues with the camshaft position synchronization, leading to a high camshaft profile control circuit reading.

It is recommended to diagnose and fix the underlying cause of the P002F fault code as soon as possible to ensure proper engine performance and prevent any further damage.

Possible Solutions

How to fix P002F?

To fix the P002F fault code on cars, you can follow these steps:

  1. Check the wiring: Inspect the wiring harness for any signs of damage or loose connections. Repair or replace any faulty wiring.

  2. Inspect the connectors: Check the connectors related to the B camshaft profile control circuit on bank 2. Ensure they are clean, free from corrosion, and properly connected. Clean or replace any faulty connectors.

  3. Test the camshaft position sensor: Use a multimeter to test the camshaft position sensor for proper voltage and resistance. Replace the sensor if it is faulty.

  4. Check the engine control module (ECM): Inspect the ECM for any signs of damage or malfunction. Test the voltage and continuity of the circuits related to the camshaft profile control circuit. Replace the ECM if necessary.

  5. Perform a diagnostic scan: Use a diagnostic scan tool to clear the fault code and reset the ECM. Monitor the system for any recurring faults after the reset.

  6. Test the camshaft actuators: Check the camshaft actuators on bank 2 for proper operation. They may be sticking or failing to adjust the camshaft profile. Replace any faulty actuators.

  7. Inspect the camshafts: Check the camshafts on bank 2 for excessive wear or damage. Replace the camshafts if necessary.

Note: It is recommended to consult the vehicle's service manual or seek assistance from a qualified mechanic to ensure proper diagnosis and repair of the P002F fault code.
