Code P0012 2008 Toyota Camry Description

The P0012 code for a 2008 Toyota Camry indicates that the camshaft position 'A' timing is over-retarded in bank 1. This means that the timing of the camshaft in relation to the crankshaft is not within the specified parameters set by the manufacturer. The camshaft position sensor monitors the position of the camshaft and sends this information to the engine control module (ECM). If the ECM detects that the camshaft timing is over-retarded, it will trigger the P0012 code.

  • You need to replace the "Bank 1 Intake Camshaft Timing OCV (RH)" (#1 on the image below). If the problem persist, then you need to replace the " Bank 1 Intake Variable Valve Timing (VVT) Gear Assembly"
