To fix code P0012, clean or replace the camshaft oil control valve. This can be done if changing the engine oil doesn’t solve the issue.
Code P0012 indicates that the cam timing is retarded and can be caused by various factors such as a faulty camshaft actuator, failed VVT solenoid, damaged timing components, circuit issues, low engine oil levels, oil contamination, or problems with the PCM.
By cleaning or replacing the camshaft oil control valve, you can address the potential issues with the variable valve timing system.
Understanding Code P0012
Understanding Code P0012 is essential when it comes to fixing it. This fault indicates that the cam timing is retarded, and it can be caused by various factors such as a faulty camshaft actuator, VVT solenoid, timing components, or circuit issues.
Low engine oil levels, oil contamination, and problems with the PCM can also trigger this code. Cleaning or replacing the camshaft oil control valve is a possible solution for engines with a variable valve timing system.
What Is Code P0012?Code P0012 is a diagnostic trouble code related to the camshaft position timing over advanced, usually found in vehicles with a variable valve timing system. The fault indicates that the cam timing is retarded, often referred to as “VANOS” in BMW terminology. The code can be triggered by various factors, including a faulty camshaft actuator, failed VVT solenoid, damaged timing components, circuit issues, low engine oil levels, oil contamination, or problems with the powertrain control module (PCM). Common Causes Of Code P0012
If changing the engine oil doesn’t resolve the issue, it is advisable to clean or replace the camshaft oil control valve. However, it is essential to consult a qualified mechanic or refer to your vehicle’s manufacturer-specific repair manual for proper diagnosis and repair instructions. |

Methods To Fix Code P0012
One method to fix Code P0012 is by performing an oil change. This could help resolve the issue if the code was triggered by low engine oil levels or oil contamination. Make sure to use the recommended oil for your vehicle.
Another method to fix Code P0012 is by checking and cleaning or replacing the camshaft oil control valve. This is applicable to engines with a variable valve timing system. A faulty or clogged valve can cause the code to appear.
If the above methods don’t work, you can try claiming a FREE Engine Code Eraser. This device can help clear the code and reset the engine’s computer.
| Method | Steps |
|---|---|
| Oil Change | 1. Drain the old engine oil 2. Replace the oil filter 3. Refill with new engine oil |
| Camshaft Oil Control Valve | 1. Locate the valve 2. Clean or replace the valve if necessary |
Remember, if you’re unsure or not confident in performing these fixes yourself, it’s recommended to consult with a professional mechanic for assistance.

Frequently Asked Questions On How To Fix Code P0012
What Causes A P0012 Code?
The P0012 code can be caused by a faulty camshaft actuator, failed VVT solenoid, timing component damage, circuit issues, low engine oil levels, oil contamination, or issues with the PCM.
What Does A Camshaft Position Timing Over-retarded Bank 1 Mean?
A camshaft position timing over-retarded bank 1 means that the timing of the camshaft on bank 1 is delayed. This can be caused by issues with the camshaft actuator, VVT solenoid, timing components, or circuit problems. Low oil levels, contaminated oil, or problems with the PCM can also trigger the code.
Clean or replace the camshaft oil control valve if changing the oil doesn’t solve the issue.
What Does A Camshaft Position Timing Over-retarded Bank 2 Mean?
A camshaft position timing over-retarded bank 2 means that the cam timing is out of sync, possibly due to a faulty camshaft actuator or issues with the timing components. It can also be caused by low engine oil levels or contamination.
Cleaning or replacing the camshaft oil control valve may help resolve the issue.
What Causes Camshaft Position Timing Over Advanced?
Camshaft position timing over advanced can be caused by a faulty camshaft actuator, failed VVT solenoid, damaged timing components, circuit issues, low engine oil levels, oil contamination, or issues with the PCM. Cleaning or replacing the camshaft oil control valve can also be a possible solution.
Conclusion
To fix Code P0012, it is important to address the underlying issues that can trigger this fault. This can include problems with the camshaft actuator, VVT solenoid, timing components, and circuitry. Additionally, low engine oil levels, oil contamination, and PCM issues can also lead to this code.
If changing the engine oil doesn’t solve the problem, cleaning or replacing the camshaft oil control valve can be a potential solution, especially for engines with a variable valve timing system. By carefully diagnosing and addressing these issues, you can effectively fix Code P0012 and ensure optimal performance of your vehicle.
