P0013 Technical Description
“B Camshaft Position – Timing Over-Retarded (Bank 1)”
If you’re seeing the P0013 trouble code in your car, you’re probably wondering what it means and how to fix it. This guide will explain everything you need to know.
I’ve dealt with P0013 codes before. It’s a common issue, but it can be fixed.
You’ll learn what the P0013 code means, the symptoms you might notice, the possible causes, and how to fix it yourself or with professional help.
So, let’s get started and figure out what’s going on with your car.
Key Takeaways
- P0013 indicates “B Camshaft Position – Timing Over-Retarded (Bank 1).”
- Common symptoms include rough idling, poor fuel economy, and decreased engine performance.
- Causes can range from faulty camshaft actuators to dirty or low engine oil.
- Check engine oil levels and quality as a first step.
- Inspect wiring, connectors, and the oil control valve for faults.
- Use an OBD-II scanner to clear the code and verify the fix.

What Does P0013 Trouble Code Mean?
The P0013 trouble code indicates a problem with the camshaft position actuator in Bank 1 of your engine.
Specifically, it means the “B” camshaft timing is over-retarded. This means the camshaft timing is delayed more than the ECU (Engine Control Unit) expects.
Your engine relies on precise timing for optimal performance. The camshaft position actuator adjusts the camshaft’s position to ensure the valves open and close at the right times.
When the actuator can’t achieve the desired timing, it triggers the P0013 code.
This can happen for several reasons. The most common include issues with the camshaft position actuator itself, wiring problems, or a faulty oil control valve (OCV).
Sometimes, dirty or low engine oil can also cause this code, as the camshaft actuator is oil-driven.
If you see the P0013 code, you might also notice rough idling, poor fuel economy, or a decrease in engine performance.
The check engine light will almost certainly be on. Ignoring this code can lead to more significant issues, so addressing it promptly is crucial.
In short, the P0013 code tells you there’s a timing problem with the “B” camshaft in Bank 1.
Understanding this can help you identify the symptoms and potential causes, leading you to the right fix.
P0013 Trouble Code Symptoms
If your car has a P0013 trouble code, you might notice several symptoms:
- Check engine light is on
- Rough idling
- Poor fuel economy
- Decreased engine performance
- Engine stalling
- Difficulty starting the engine
P0013 Trouble Code Causes
Several issues can cause the P0013 trouble code to appear:
- Faulty camshaft position actuator
- Wiring problems in the actuator circuit
- Malfunctioning oil control valve (OCV)
- Dirty or low engine oil
- Timing chain or belt issues
- Faulty ECU (Engine Control Unit)
How To Fix a P0013 Trouble Code
Fixing a P0013 trouble code involves diagnosing the actual issue and following the correct repair procedures. Here’s how you can do it:
1. Check the Engine Oil
Ensure your engine oil is clean and at the proper level. Dirty or low oil can affect the camshaft actuator’s performance. If needed, perform an oil change and reset the code to see if it resolves the issue.
2. Inspect the Wiring and Connectors
Examine the wiring and connectors to the camshaft position actuator. Look for signs of damage, corrosion, or loose connections. Repair or replace any faulty wiring or connectors.
3. Test the Camshaft Position Actuator
Use a multimeter to check the resistance of the camshaft position actuator. Refer to your vehicle’s service manual for the correct specifications. If the actuator is out of spec, replace it.
4. Check the Oil Control Valve (OCV)
The OCV regulates oil flow to the camshaft actuator. Test the OCV for proper operation. If it’s faulty, replace it.
5. Inspect the Timing Chain or Belt
Ensure the timing chain or belt is in good condition and properly aligned. Misalignment or wear can cause timing issues. Replace any worn or damaged components.
6. Scan for Additional Codes
Sometimes, the P0013 code can be accompanied by other trouble codes. Use an OBD-II scanner to check for additional codes that might help pinpoint the issue.
7. Reset the Code
After making the necessary repairs, use an OBD-II scanner to clear the trouble code. Drive the vehicle to see if the code reappears. If it does, further diagnosis may be required.
By following these steps, you can effectively diagnose and fix the issue causing the P0013 trouble code in your car.
