Replacing the camshaft oil control valve for bank 1 intake camshaft.Д¬heck the timing chain alignment for jumped timing problems and repair as needed.ДЄdditional comments for consideration regarding the P0012 code Repairing or replacing the wiring or connection to the camshaft oil control solenoid.

Resetting the fault codes and performing a road test.Д¬hanging the oil and filter to the proper oil viscosity for the engine's specifications. The engine may have excessive fuel consumption, carbon fouling of engine components, and various drive complaints depending on the camshaft failed position.Дriving the vehicle for a prolonged time with the camshafts not retarding may cause other problems to the valve train or engine depending on the cause of the failure. The engine may run erratic and stall, hesitate, run rough or have a hard starting condition. Common mistakes when diagnosing the P0012 code?ДЇollow these simple guidelines to prevent mistakes:ДЄlways verify the failure before attempting any repairs.Дo a thorough visual check for any problems with the wiring or connections to the components.ДЇollow the pinpoint test step-by-step to help prevent a misdiagnosis.Дo not replace any parts unless directed by the pinpoint or visual testing. Note: Follow the manufacturer's recommended pinpoint test to narrow down the problem, since each engine may be tested differently and possible engine internal damage may be done if tests are not performed in accordance with a correct procedure. If no problems are noted and the code still exists, then the next step for the technician is to perform a manufacturer's specific pinpoint tests for the P0012 code and repair as needed. The codes should then be reset to clear the OBD-II fault codes and retest the vehicle to see if the P0012 code comes back.Д¬ommands the oil control solenoid valve on and off to see if the camshaft timing changes. The technician will scan and document the codes received and view the freeze frame data to see when the code was set.

Makes sure the engine oil is full of clean correct viscosity oil. Visually checks the electrical connections to the camshaft sensor, oil control solenoid valve, and crankshaft sensor for loose connections, damaged wiring harness, or any other issues that may cause a problem.

How does a mechanic diagnose the P0012 code? Note: Your drive problems will change depending on the camshaft timing positions when the camshaft stopped advancing. The engine will have a hard start condition due to the retarded timing position.ДЇuel mileage may go down since the camshaft is not in a position to get the best possible fuel mileage.Дepending on camshaft position the engine may stall, hesitate, and run rougher than normal. The ECM will turn on the Check Engine Light if the timing cannot be commanded to move.

Oil flow problems to the VCT piston and phaser.

The camshaft phaser is damaged and stuck in the retarded position.

The variable camshaft timing (VCT) oil control valve (OCV) stuck in the open position.

This over-retarded timing condition could be during the advancing or retarding phase of the camshaft timing. P0012 is the OBD-II generic code indicating the engine control module (ECM) has determined that the intake camshaft timing for bank 1 is more retarded than what the ECM has commanded it be.
