YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. If the camshaft phaser is leaking oil or the phaser is broken internally then both phasers should be replaced on both banks of the cams. The camshaft phaser controls the timing advance and retard function through oil pressure and oil.

Common mistakes when diagnosing the P0015 code?įollow these simple guidelines to prevent mistakes: Possible engine internal damage may be done if tests are not performed in accordance with a correct procedure. Note: The manufacturer's recommended pinpoint test is used to narrow down the problem. Performs the manufacturer’s tests for the P0015 code Resets the Check Engine Light and road tests again to see if the code returnsĬommands the OCV on and off with the scan tool to see if the camshaft timing changes Scans and documents engine codes and views the freeze frame data to see when the code was set How does a mechanic diagnose the P0015 code?ĭoes a visual check for problems with the connections or wiring of the OCVĬhecks the engine oil to see if it is full of clean correct viscosity oil Note: The camshaft position will cause erratic drive complaints depending on the camshaft failed position. The engine may stall, hesitate, and run rougher than normal. The engine will have a hard start and low power condition due to the retarded timing position. The Check Engine Light comes on if the timing is commanded to move, but it stays retarded. The OCV has an open circuit or the ECM has an open circuit. Oil flow problems to the VCT piston and phaser from incorrect oil viscosity. The camshaft phaser is stuck in the retarded position due to damage or clogged oil passages. The variable camshaft timing (VCT) oil control valve (OCV) is stuck in the open position. The over-retarded timing condition can be during the advancing or retarding phase. P0015 is the OBD-II generic code indicating the engine control module (ECM) has determined that the exhaust camshaft timing for bank 1 is more retarded than what the ECM has commanded it to be.
