P001F Fault Code

P001F OBD-II Trouble Code Short Description

A Camshaft Profile Control Circuit High Bank 2

What does trouble code P001F mean?

The P001F fault code refers to a Camshaft Profile Control Circuit High in Bank 2. This means that there is a malfunction in the circuit responsible for controlling the camshaft's profile in the second bank of cylinders.

The camshaft profile control circuit is typically controlled by the engine control module (ECM) and is used to adjust the timing and lift of the camshaft, optimizing engine performance. When the ECM detects that the voltage in the circuit is higher than the specified range, it triggers the P001F fault code.

There are a few possible causes for this fault code. It could be due to a malfunctioning camshaft position sensor, a faulty actuator solenoid, wiring issues, or even a problem with the ECM itself. Additionally, mechanical issues like a stuck camshaft phaser or a worn timing chain can also contribute to this fault.

To diagnose and fix the issue, it is recommended to perform a thorough inspection of the camshaft profile control circuit, including checking the wiring and connectors for any damage or loose connections. The camshaft position sensor and actuator solenoid should also be tested to ensure they are functioning correctly. If any faulty components are identified, they should be replaced.

It is worth noting that resolving the P001F fault code may require specialized equipment and expertise, so it is often best to consult a qualified mechanic or dealership for proper diagnosis and repair.

Overall, the P001F fault code indicates a problem with the camshaft profile control circuit in Bank 2, and addressing the underlying issues will ensure optimal engine performance and reliability.


What are the symptoms of the P001F code?

The P001F fault code refers to a Camshaft Profile Control Circuit High Bank 2. Some common symptoms of this code include:

  • Check Engine Light (CEL) illuminated
  • Rough idling or poor engine performance
  • Reduced power and acceleration
  • Engine misfires or stalls
  • Increased fuel consumption
  • Issues with starting the engine

It is important to note that these symptoms may vary depending on the specific make and model of the vehicle.


What causes the P001F code?

The fault code P001F typically indicates a problem with the Camshaft Profile Control Circuit on Bank 2 of the engine. This code is often triggered when the engine control module (ECM) detects a high voltage or resistance in the camshaft profile control circuit on Bank 2.

Some possible causes for this fault code include:

  1. Faulty camshaft position sensor: A malfunctioning camshaft position sensor can send inaccurate signals to the ECM, leading to the P001F code.

  2. Wiring or connector issues: Damaged or loose wiring, as well as faulty connectors, can disrupt the flow of electricity and cause the circuit voltage to become higher than normal.

  3. ECM malfunction: A malfunctioning ECM can mistakenly interpret the camshaft position signals, triggering the P001F fault code.

  4. Mechanical issues: Problems with the camshaft itself, such as wear, damage, or timing issues, can also cause the P001F code.

  5. Timing chain or belt problems: A stretched or improperly tensioned timing chain or belt can negatively affect the camshaft's operation, leading to the fault code.

It is important to diagnose and address the root cause of the P001F fault code to prevent further engine damage or drivability issues. It is recommended to consult a qualified mechanic or use professional diagnostic tools to accurately identify and resolve the issue.

Possible Solutions

How to fix P001F?

To fix the P001F fault code, which is related to the Camshaft Profile Control Circuit High in Bank 2, follow these steps:

  1. Check the wiring: Start by inspecting the wiring harness and connectors associated with the camshaft position sensors and the camshaft profile control solenoid. Look for any signs of damage, loose connections, or corrosion. Repair or replace any faulty wiring or connectors.

  2. Test the camshaft position sensors: Use a multimeter to test the camshaft position sensors' resistance and voltage values. Compare the readings to the specifications provided by the vehicle manufacturer. Replace any sensors that do not meet the specified values.

  3. Inspect the camshaft profile control solenoid: Check the camshaft profile control solenoid for any signs of damage or obstruction. Remove and clean the solenoid if necessary. Test it using a 12V power source and a multimeter to ensure it is functioning correctly. Replace the solenoid if it is faulty.

  4. Verify oil pressure: Low oil pressure can cause issues with the camshaft profile control circuit. Check the engine's oil level and pressure. If the oil level is low, top it up. If the oil pressure is below specifications, further investigation may be required to determine the cause.

  5. Clear the fault code: After performing the necessary repairs or replacements, use an OBD-II scanner to clear the fault code from the vehicle's computer. This will reset the system and allow you to monitor if the issue has been resolved.

It is recommended to consult the vehicle's service manual or seek assistance from a qualified mechanic for a more specific and accurate diagnosis and repair procedure.
