Diagnosis Procedure
1.CHECK GROUND CONNECTIONS
1. Turn ignition switch OFF and wait at least 20 seconds.
2. Check ground connection E38. Refer to Ground inspection in GI-44, "Circuit Inspection".
Is the inspection result normal? YES >> GO TO 2.
NO >> Repair or replace ground connection.
2.CHECK THROTTLE POSITION SENSOR POWER SUPPLY CIRCUIT
1. Disconnect electric throttle control actuator harness connector.
2. Turn ignition switch ON.
3. Check the voltage between electric throttle control actuator harness connector and ground.

Is the inspection result normal? YES >> GO TO 3.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
3.CHECK THROTTLE POSITION SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF and wait at least 20 seconds.
2. Disconnect ECM harness connector.
3. Check the continuity between electric throttle control actuator harness connector and ECM harness connector.

4. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
4.CHECK THROTTLE POSITION SENSOR INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Check the continuity between electric throttle control actuator harness connector and ECM harness connector.

2. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
5.CHECK THROTTLE POSITION SENSOR
Refer to EC-910, "Component Inspection".
Is the inspection result normal? YES >> GO TO 7.
NO >> GO TO 6.
6.REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR
