P0015: Camshaft Position B - Timing Over-Retarded (Bank 1)
Can you still drive? Yes, but schedule repairs soon. Continued driving with incorrect camshaft timing reduces performance and fuel economy, and prolonged neglect can damage the engine.
What Does P0015 Mean?
Code P0015 indicates that the exhaust camshaft on bank 1 is more retarded than the ECM commanded. The variable valve timing system is not positioning the camshaft correctly, resulting in poor engine performance. This is often related to oil flow issues or a faulty VVT actuator.

Frequently Asked Questions
Can an oil change fix P0015?
Sometimes yes. Dirty or low oil is a common cause because the VVT system relies on oil pressure. Perform an oil change with manufacturer-recommended oil and clear the code to see if it returns.
What is the difference between P0014 and P0015?
P0014 means the exhaust camshaft is over-advanced, while P0015 means it is over-retarded. Both point to VVT system issues but indicate opposite timing faults.
