If any related repair information is available, perform repair or diagnosis according to available repair information. If vehicle is not repaired, go to next step. If related repair information is not available, go to next step.
  3. Inspect OCV For Malfunction -  Start engine. Increase engine speed. Stop engine. Remove OCV. Inspect position of spool valve in OCV. If spool valve is in retard position, go to next step. If spool valve is not in retard position, replace OCV. After repair, go to step  6.
  4. Inspect Variable Valve Timing Actuator -  Remove timing belt. Inspect Variable Valve Timing (VVT) actuator. If VVT actuator is okay, go to next step.

After repair, go to next step.
