Tech Notes for P0010 2003 Toyota Corolla

If the engine oil is clean and the VVT and OCV circuits are OK, replaced the VVT to resolve the problem.

When is the Code Detected?

After the ECM sends the target duty cycle signal to the OCV, the ECM monitors the OCV current to establish an actual duty cycle. The ECM determines the existence of a malfunction and sets the DTC when the actual duty cycle ratio varies from the target duty cycle ratio.
