On the 2010 Toyota Camry 2.5L engine, the P0015 is pointing to a problem with the Exhaust Camshaft Oil Control Valve. This can also be an issue of Valve timing (timing jumped – not very common). A problem with the camshaft gear assembly (not very common). Or a problem with the ECM (on-board computer, also not very common). More commonly here, you will usually find the oil control valve screen is clogged. You can find the valve located on the passenger’s side, rear of the engine, just to the side of the oil fill cap. Carefully inspect the electrical connector and wire harness for any loose, broken or damaged wires. If the visual inspection checks ok, suspect a faulty Exhaust Camshaft Oil Control Valve. Replacement should solve the problem.
