Tech Notes for P0011 2003 Toyota Corolla

Valve timing may have to be adjusted.

When is the Code Detected?

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