![]() The PCM sends an alert to the driver whenever the camshaft retards or advances. There are many things that can cause a P0012 code, and it needs to be figured out as soon as possible. In other words, the P0012 code is set off when the powertrain control module (PCM) notices that the intake (A) camshaft has stayed in the retarded position or that the intake (A) camshaft timing on bank 1 is different from what is wanted. This indicates a difference between the desired and actual position angles of the camshaft. The P0012 trouble code means that the camshaft position of intake A is over-retarded at bank 1 (cylinder 1). In Conclusion What Does The P0012 Code Mean?.How Much Does It Cost To Repair P0012 Code.Most Common Mistakes When Diagnosing The P0012 Code.What Are The Common Symptoms of The P0012 Code?.What Are The Possible Causes of the P0012 Code?.Which Models Are Affected By The P0012 Code.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.There may be oil flow problems to the phaser and the VCT piston.The VCT oil control valve could be stuck in the open position.The camshaft phaser may be damaged and stuck in the retarded position.The increased fuel consumption means the car is likely to fail an emissions test.The engine may become prone to stalling or running rough depending on the camshaft position.The issue with camshaft positioning may lead to higher fuel consumption.The retarded starting position may cause the engine to have a hard start.The if ECM is unable to command the timing to move, the Check Engine Light will be illuminated.This condition can be detected during the advancing or retarding section of the camshaft timing process. Error code P0012 is a generic code which indicates that ECM believes the intake camshaft timing for bank 1 is more retarded that it was instructed to be. ![]()
