![]() ![]() Sometimes, the system will get stuck in an over-advanced position. It can advance or retard the timing at will. VVT allows an engine to act as though it has different camshaft profiles at different RPMs this is great for both power and fuel economy. Adjusting the camshaft timing allows an engine to have a better power curve and better fuel economy (the automotive equivalent of having your cake and eating it too).ĭepending on the vehicle, the “B” camshaft is the exhaust, right or rear camshaft. “B” Camshaft PositionĮngines equipped with VVT use camshaft actuators (they’re often called phasers) to adjust the position of the cam. Here it is separated into its three main pieces, with a quick explanation of each. ![]() The technical definition of P0014 for the Acadia is “B” Camshaft Position Timing Over Advanced or System Performance (Bank 1). Not usually, but in rare cases, the underlying causes can damage the engine. Low oil, wrong oil viscosity, faulty camshaft actuator, timing chain/belt jumped Stalling, decreased MPG, rattling, engine running rough, check engine light “B” Camshaft Position Timing Over Advanced or System Performance (Bank 1) P0014 Quick Reference Table P0014 Definition Low oil is the number one cause of P0014. P0014 means that the camshaft position is too far advanced from where it should be in relation to normal operating specs.īefore doing anything, check your Acadia’s oil level. VVT adjusts the position of the camshaft(s) to maximize the combustion efficiency of the motor. The oil control valve itself may need replaced if it is overly worn or damaged.P0014 is a relatively common trouble code for vehicles that have Variable Valve Timing (VVT). This will be determined during the visual inspection. The wiring for the oil control valve for the bank 1 exhaust camshaft may need to be repaired or replaced. When replacing the oil, make sure to check the manufacturer’s recommendations to ensure the right product is used. Replacing the oil can help resolve the error code if there was an issue with the viscosity. Resetting the error and performing a road test will help determine the conditions which result in the error, making it easier to fix. Replacing any components without determining the specific problem is likely to result in the error reoccurring and the repair becoming more expensive than it needs to be. It’s important that pinpoint diagnostic testing is undertaken to ensure the exact cause of the error is determined. If the timing changes, it indicates that the issue is with the ECM or is potentially a wiring issue. If the error is triggered again, noting the circumstances can make it easier to perform a pinpoint diagnosis.Īnother diagnostic step is to monitor the timing data when disconnecting the oil control valve to the exhaust camshaft. The oil viscosity should be checked to see if it matches the manufacturer’s recommendation.Īs with most OBD2 error codes, it’s best to take a screen shot of the error before resetting and performing a road test to see if it reoccurs. In case of an error P0014, the wiring, valves and connections should be checked in the oil control valve of the bank 1 exhaust camshaft.
