Standard:

If the operation is not as specified, check the camshaft timing oil control valve, wire harness and ECM.

2. INSPECT THROTTLE BODY ASSY
a. Listen to the throttle control motor operating sounds.
1. Turn the ignition switch to ON.
2. When pressing the accelerator pedal, listen to the running sounds of the motor. Make sure no friction noises come from the motor. If friction noises exist, check the throttle body, wire harness and ECM.




b. Inspect the throttle position sensor.
