An oil control valve, also known as an OCV or a VVT solenoid, is part of the variable valve timing system. It plugs into the car’s main wiring harness and should be found somewhere in the upper part of the engine.

How do I fix the code P0012 on my BMW?
How do I fix my P0012 code?
What repairs can fix the P0012 code? Resetting the fault codes and performing a road test. Changing the oil and filter to the proper oil viscosity for the engine’s specifications. Repairing or replacing the wiring or connection to the camshaft oil control solenoid.
What does a camshaft position timing over Retarded Bank 1 mean?
Diagnostic trouble code (DTC) P0012 stands for “Intake (A) Camshaft Position Timing – Over-Retarded (Bank 1).” The code indicates that your car’s computer has detected a difference in the desired camshaft position angle and the actual camshaft position angle.
Is code P0012 serious?
The P0012 engine is a sign of serious trouble with your engine. Don’t try to drive a car with this trouble code — take it to a trusted mechanic as soon as possible to avoid further damage.
Can low oil cause P0012?
Q: Can low oil cause P0012? A vehicle engine oil should be at the manufacturer’s specification at all times. The camshaft variable valve timing systems work with adequate oil levels and pressure. If the engine oil goes below the specification, it can cause P0012 errors and multiple error codes.
What is the camshaft position sensor bank 1?
Bank 1 is the side of your engine that has the cylinder 1, while sensor B refers to the exhaust camshaft side.
What can cause a P0012 code?
- Engine oil is too low*
- Dirty/sludged engine oil*
- Low oil pressure.
- Malfunctioning camshaft timing.
- Short in intake timing control/oil control circuit.
- Faulty intake valve timing control solenoid.
- Faulty oil control valve (OCV)
Will an oil change fix P0012?
Causes of Code P0012 For starters, you could have the wrong engine oil, low engine oil, or extremely old engine oil. This is the best-case scenario, but there’s no guarantee that changing the oil will fix your problem.
What causes intake camshaft position timing?
These are the most likely causes: The camshaft timing is off. The valve control solenoid is stuck open. The valve control solenoid system has faulty or damaged wiring.
How much does it cost to fix a camshaft timing?
To replace a camshaft position sensor, you can expect to pay anywhere from $95 to $200. Parts alone will run about $25 to $100. Labor costs will be in the range of $70 to $100 for professional replacement. Expect to pay more if you have a luxury vehicle or are having your local car dealership perform the replacement.
What does intake a camshaft position Timing Over Advanced Bank 1?
What Does the P0011 Code Mean? The P0011 DTC stands for “A” Camshaft Position Timing Over Advanced or System Performance Bank 1. The code indicates that the ECM/PCM has been unable to correct a detected difference in the desired camshaft position angle and the actual camshaft position angle.
What does camshaft position mean?
The camshaft position sensor gathers information about the vehicle’s camshaft speed and sends it to the vehicle’s engine control module (ECM). The ECM uses this data to determine the timing of the ignition, as well as the timing of the fuel injection that the engine requires.
What is a camshaft timing oil control valve?
How do I fix the code P0015 on my BMW?
- Resetting the fault codes and performing a road test.
- Replacing camshaft phasers on both camshaft banks.
- Repairing the wiring or connection to the camshaft OCV.
- Replacing the camshaft OCV for bank 1 exhaust camshaft.
- Replacing timing chain and guides.
How do I know if my VVT is working?
Common signs include a rough engine idle, the Check Engine Light coming on, and the engine stumbling when climbing hills or under load.
What does cam phaser do?
One or more camshaft actuators—also known as camshaft phasers—act as the heart of the VVT system. When conditions are correct, the phasers alter the position of the camshafts to adjust the engine’s valve timing. Although camshaft phasers sound great in theory, they’re a common failure point on many modern engines.
How do you reset a camshaft position sensor?
How to reset the camshaft position sensor? Evidently, you cannot reset a camshaft position sensor. Therefore, you will need to replace the component if your camshaft malfunctions (check engine light on, acceleration issues, sputtering and stalling, etc.).
What are the symptoms of a faulty cam sensor?
A glowing check engine light, stalling, poor acceleration and bad fuel mileage are all possible signs your camshaft position sensor may be failing. Gone are the days of carburetors and distributors, replaced by a variety of sensors that help a car’s computer get the maximum performance out of the engine.
Are there 2 camshaft position sensors?
While the number can vary based on the age of your car, a new car should have four camshaft sensors, one for each camshaft. A camshaft sensor determines the exact position of your engine’s camshaft, helping your car keep your engine’s combustion running smoothly.
How do you test a variable valve timing solenoid?
How much does it cost to fix p0022 code?
Depending on the shop’s labor rate, this typically costs somewhere between $75-$150.
How much does it cost to fix P0011?
How Much Does It Cost To Repair Code P0011. The cost of fixing error code P0011 can range from $40 to $2000 depending on the cause of the problem and the age of the vehicle. At the lower end of the scale, a simple oil and filter change can cost $50 to $100.
What is VCT solenoid?
The variable valve timing solenoid is a component of the variable valve timing system that manages the oil flow depending on the engine speed and load.
How do I fix code P0340?

- Repairing or replacing the camshaft position sensor circuit connector.
- Replacing the camshaft position sensor.
- Replacing the crankshaft position sensor.
