This DTC sets when the current necessary to operate the throttle actuator control (TAC) motor is higher than a calibrated limit.
Item | Detecting Condition | Possible Cause | |
Case 1 | DTC Strategy |
•
Throttle response check | 1. Poor connection 2. Short in motor circuit 3. ETC motor 4. Obstruction in the throttle plate movement |
