The camshaft position actuator solenoid valve regulates the oil flow to the actuator, which then adjusts the camshaft’s position. This article discusses the error code P0013 meaning, symptoms, causes, and fixes.
P0013 Code Definition
Diagnostic trouble code (DTC) P0013 stands for “Exhaust “B” Camshaft Position Actuator Circuit/Open (Bank 1).
What Does the P0013 Code Mean?
The P0013 engine code indicates that your powertrain control module (PCM) has monitored that the bank 1 exhaust camshaft Oil Control Valve has an open circuit or short circuit.
In a traditional engine, the valve timing is fixed, but a variable valve timing engine allows for adjustments to the camshaft position, which can alter the valve timing. This system, known as variable camshaft timing or VVT, typically includes camshaft actuators (phasers) and variable valve timing solenoids (camshaft position actuator solenoid valves). By regulating the oil flow to the actuator, the camshaft can be advanced or retarded, leading to improved performance, increased fuel efficiency, or both.
The camshaft position actuator solenoid valve plays a crucial role in the VVT system by controlling the oil flow to the actuator.
The PCM of your car is responsible for operating the solenoid and monitoring its circuit. If there is an issue with the camshaft actuator solenoid or its circuit, the PCM triggers DTC P0013.
Causes of P0013 Code
The P0013 code is a generic OBD-II trouble code that indicates an issue with the camshaft position actuator circuit. Follow are the major causes of the P0013 code:
- Faulty camshaft position actuator solenoid valve
- Malfunctioning crankshaft position sensor

How to diagnose the P0013 Code
Diagnosing a P0013 code involves a series of steps that a qualified mechanic can perform to determine the underlying cause of the code. Here are the steps you may follow to diagnose a P0013 code:
- Use a Scan Tool: Ensure the existence of the P0013 by using an OBD-II scan tool.
- Check for other codes: A P0013 code may be accompanied by other codes that can provide additional information about the issue.
- Perform a test drive: Clear the codes stored in the PCM memory using the OBD-II scanner and perform a test drive. If the code returns, move forward for further inspection.
- Perform a visual inspection: Inspect the wiring and connectors associated with the camshaft position actuator solenoid valve for damage, corrosion, or loose connections.
- Check the engine oil: Low or dirty oil levels can cause a P0013 code. Therefore, check the engine oil level and quality and change the oil if necessary.
- Test the camshaft position sensor: The camshaft position sensor is responsible for detecting the position of the camshaft and sending a signal to the engine control module (ECM). If the sensor is faulty or has a poor connection, it can trigger the P0013 code. Check the sensor and its wiring for any signs of damage, and replace the sensor if necessary.
- Test the camshaft position actuator solenoid valve: Test the solenoid valve’s electrical connections. Use a multimeter to check for proper voltage and resistance. If the solenoid valve is faulty, it will need to be replaced.
- Check the timing chain: The timing chain can cause a P0013 code if it is loose, stretched, or broken. Inspect the timing chain and associated components for wear and damage.
- Check the engine control module (ECM): If all of the above steps have been checked and the P0013 code persists, the problem may be with the ECM itself. The ECM controls the camshaft position actuator circuit, so if it is faulty, it can trigger the P0013 code. If this is the case, the ECM will need to be replaced or reprogrammed.
P0013 Code Diagnostic Mistakes
- Not checking the engine oil: Low or dirty engine oil can cause issues with the VVT system and trigger the P0013 code. Failing to check the engine oil level and condition can lead to unnecessary repairs.
- Not checking the timing chain or belt: A loose or worn timing chain or belt can cause issues with the camshaft position actuator circuit. Failing to inspect the timing chain or belt can lead to misdiagnosis and unnecessary repairs.
- Replacing the camshaft position actuator solenoid without checking for debris: The camshaft position actuator solenoid can become clogged with debris, leading to a malfunction. Before replacing the solenoid, inspect it for any debris and clean it if necessary.
- Replacing the camshaft position sensor without checking the wiring: A faulty or damaged wiring connection to the camshaft position sensor can cause the P0013 code. Before replacing the sensor, check the wiring for any signs of damage or corrosion.
- Not clearing the code after repairs: After making any repairs or replacements, it’s important to clear the code and test drive the vehicle to ensure that the P0013 code does not reappear. Failing to do so can lead to confusion and further misdiagnosis.
