![]() Oil and filter change oil with a viscosity that matches the engine specifications.Clearing fault codes and performing a road test.Driving the vehicle for extended periods of time with the reverse camshafts not engaged can cause other valvetrain or engine problems depending on the cause of the malfunction. ![]() The engine may have excessive fuel consumption, carbon contamination of engine components, and various drive complaints depending on the faulty camshaft position.The engine may run erratically and stall, oscillate, run rough, or be difficult to start.Do not replace any parts unless directed by spot or visual testing.Follow step-by-step instructions to prevent misdiagnosis.Perform a thorough visual inspection for any wiring or component connection problems.Always check for a fault before attempting to repair.The use of the wrong kind of oil can trigger code P0012, as well as various other related error codes. It can also cause various issues with the engine. If the oil is too thick the system can malfunction and trigger a number of error codes. Due to the nature of these components, the oil needs to be the right viscosity in order for it to function as intended. The timing of the advance and retard is controlled by camshaft phaser controls using oil and oil pressure. Visual inspections should be performed to correct any obvious issues, while a pinpoint diagnosis will ensure that the correct fault is repaired. When attempting to repair the P0012 error code it’s important to verify the exact cause of the error. Check the timing chain alignment for any potential issues.Replace the camshaft oil control valve for the bank 1 intake camshaft.Replace or repair the wiring and connections to the camshaft oil control solenoid.Change the oil filter and ensure the viscosity of the oil matches the manufacturers recommendations.Reset all codes and perform a road test to see if it reoccurs.If nothing is found and the code is still being triggered, a pinpoint test may be required.Turn the oil control solenoid off and on and monitor the camshaft timing to see if it changes.Restart the vehicle and retest to see if the error returns.Take a screenshot of the error before resetting the code.Check the engine oil to ensure it’s clean and the viscosity matches the manufacturer’s recommendation.Inspect all the connections to the sensor in the camshaft and the oil control solenoid valve, looking for damaged wiring or loose connections. ![]()
