P0013 Fault Code

P0013 OBD-II Trouble Code Short Description

"B" Camshaft Position - Actuator Circuit (Bank 1)

What does trouble code P0013 mean?

The P0013 fault code indicates a problem with the "B" camshaft position actuator circuit in bank 1 of the engine. This fault code is commonly found in vehicles with variable valve timing (VVT) systems.

The camshaft position actuator is responsible for controlling the timing of the camshaft, which affects the opening and closing of the engine's valves. When the Engine Control Module (ECM) detects an issue with the actuator circuit, it triggers the P0013 fault code.

There can be several reasons behind the P0013 code, including a faulty camshaft position sensor, a malfunctioning actuator solenoid, wiring or connector problems, or issues with the ECM.

To diagnose and fix the problem, it is recommended to follow these steps:

  1. Inspect the electrical connections: Check the wiring harness and connectors related to the camshaft position sensor and actuator solenoid for any signs of damage, corrosion, or loose connections. Repair or replace any faulty components.

  2. Test the camshaft position sensor: Use a multimeter to measure the sensor's resistance and voltage output. If the readings are out of the manufacturer's specified range, replace the sensor.

  3. Check the actuator solenoid: Test the solenoid by applying voltage to it and observing if it operates properly. Replace it if it fails the test.

  4. Verify proper oil flow: Insufficient or contaminated engine oil can affect the VVT system's performance. Check the oil level and condition. Also, ensure the oil passages and the VVT components are clean and free from debris.

  5. Perform an ECM scan: Use a diagnostic tool to scan the ECM for any additional trouble codes and retrieve freeze frame data. This information can help pinpoint the root cause of the issue and guide further diagnosis.

It is important to address the P0013 fault code promptly as it can lead to poor engine performance, decreased fuel efficiency, and potential damage to other engine components. If you are not experienced with automotive repairs, it is recommended to consult a professional mechanic for accurate diagnosis and proper resolution of the issue.


What are the symptoms of the P0013 code?

Symptoms of the P0013 fault code on cars may include:

  • Check Engine Light (CEL) is illuminated
  • Engine may idle rough or stall
  • Decreased fuel efficiency
  • Engine may hesitate or have reduced power
  • Engine may run roughly or misfire
  • Engine may have difficulty starting

Please note that these symptoms may vary depending on the make and model of the vehicle. It is always recommended to consult a qualified mechanic or use an OBD-II scanner to diagnose and repair the specific issue related to the fault code.


What causes the P0013 code?

The P0013 fault code refers to a "B" Camshaft Position - Actuator Circuit issue in Bank 1 of the engine. It is commonly found in cars and can be caused by the following factors:

  1. Faulty or malfunctioning camshaft position actuator solenoid.
  2. Wiring issues, such as loose connections, damaged wires, or short circuits.
  3. Mechanical problems with the camshaft phaser or timing chain.
  4. Low engine oil level or poor oil quality, leading to reduced oil pressure.
  5. ECM (Engine Control Module) software or firmware malfunction.

It is important to note that this fault code may have different causes depending on the make and model of the vehicle. It is always recommended to consult the vehicle's specific diagnostic manual or seek professional assistance to accurately diagnose and repair the issue.

Possible Solutions

How to fix P0013?

To fix the P0013 fault code on cars, follow these steps:

  1. Check the oil level: Low oil levels can cause issues with the camshaft position actuator. Make sure the oil level is adequate.

  2. Inspect the camshaft position actuator solenoid: The P0013 code can often be triggered by a faulty camshaft position actuator solenoid. Inspect it for any signs of damage or corrosion. If necessary, replace the solenoid.

  3. Check the wiring and connectors: Inspect the wiring and connectors associated with the camshaft position actuator circuit. Look for any frayed wires, loose connections, or damaged connectors. Repair or replace as needed.

  4. Inspect the camshaft phaser: The camshaft phaser is responsible for adjusting the camshaft timing. Inspect it for any signs of wear or damage. If necessary, replace the phaser.

  5. Check the timing chain or belt: A stretched or worn timing chain or belt can also cause the P0013 code. Inspect the timing chain or belt for any signs of damage or wear. If needed, replace the timing chain or belt.

  6. Clear the fault code: Once you have addressed the underlying issue, clear the fault code using an OBD-II scanner. This will reset the check engine light.

If the P0013 code persists after performing these steps, it is recommended to consult a professional mechanic for further diagnosis and repair.
