*1: LHD models or RHD with CVT models *2: RHD with M/T models
4. Also check harness for short to ground.
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
3.CHECK APP SENSOR 1 GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between APP sensor harness connector and ECM harness connector.
*1: LHD models or RHD with CVT models *2: RHD with M/T models
4. Also check harness for short to power.
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK APP SENSOR INPUT SIGNAL CIRCUIT
1. Check the continuity between APP sensor harness connector and ECM harness connector.
*1: LHD models or RHD with CVT models *2: RHD with M/T models
2. Also check harness for short to ground and to power.
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK APP SENSOR
Check the APP sensor. Refer to EC-387, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".
NO >> Replace accelerator pedal assembly. Refer to EM-28, "Exploded View".
Component Inspection
1.CHECK ACCELERATOR PEDAL POSITION SENSOR
