Diagnostic Procedure
Component Inspection
THROTTLE CONTROL MOTOR
1. Disconnect electric throttle control actuator harness connector.
2. Check resistance between terminals 5 and 6.
Resistance: Approximately 1 - 15 ohms [at 25 °C (77 °F)]
3. If NG, replace electric throttle control actuator and go to next step.
4. Perform EC-78, "Throttle Valve Closed Position Learning". Throttle Valve Closed Position Learning
5. Perform EC-78, "Idle Air Volume Learning". Programming and Relearning
