How do I clear 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.
Why does my Mazda CX 7 have a p0012 code?
If there was an electrical issue with the actuator solenoid or its circuit you would see codes P2088 or P2089. If it only acts up after driving other potential causes are wear in the camshaft bearings allowing a cross feed of the oil flow and loss of the camshaft actuator. It could also be due to loss of oil pressure due to wear or sludging.
What causes the variable camshaft timing code p0012?
This over-retarded timing condition could be during the advancing or retarding phase of the camshaft timing. What causes the P0012 code? The variable camshaft timing (VCT) oil control valve (OCV) stuck in the open position.
What are the symptoms of the p0012 OBD-II code?
The variable camshaft timing (VCT) oil control valve (OCV) stuck in the open position. The camshaft phaser is damaged and stuck in the retarded position. Oil flow problems to the VCT piston and phaser. What are the symptoms of the P0012 code? The ECM will turn on the Check Engine Light if the timing cannot be commanded to move.
What does trouble code mean on Mazda CX 7?
The trouble code means that the camshaft timing is over retarded. The PCM looks at the camshaft sensor signal and measures it against the crankshaft sensor signal to determine exactly how the cam and crank are synchronized.

What is the cel code for a Mazda CX7?
I have a 2009 CX7 with 95,000 KLMs. It runs great and I am quite happy with it. However, I am getting an intermittent CEL with a code of P0012. I know that is the variable valve timing actuator. The CEL comes on once a week or so for a day and then resets itself.
Can a Mazda CX-9 have variable valve timing?
It affects vehicles with variable valve timing (VVT). The list of VVT vehicles is growing, and the Mazda CX-9 can have VVT, and is known to develop this code. P0012 is generic, which means that it has the same definition for the CX-9 as it does on any other vehicle.
What does the p0012 code on an ECM mean?
The camshaft (s) is (are) adjusted by the ECM through the use of an oil control valve (s) (OCV) also called variable valve timing control solenoid valves. The P0012 code is set when the ECM detects the camshaft timing for the intake camshaft on bank 1 is more retarded than what it has been set to be. What Are The Symptoms Of Code P0012?
