2. Disconnect ECM harness connector.
3. Check the continuity between APP sensor harness connector and ECM harness connector as follows.
*1: LHD models or RHD models with CVT *2: RHD models with M/T
4. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 8.
NO >> Repair open circuit or short to ground or shot to power in harness or connectors.
8.CHECK APP SENSOR INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Check the continuity between APP sensor harness connector and ECM harness connector as follows.
*1: LHD models or RHD models with CVT *2: RHD models with M/T
2. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 9.
NO >> Repair open circuit or short to ground or shot to power in harness or connectors.
9.CHECK APP SENSOR
Refer to EC-760, "Component Inspection".
Is the inspection result normal? YES >> GO TO 11.
NO >> GO TO 10.
10.REPLACE ACCELERATOR PEDAL ASSEMBLY
Replace accelerator pedal assembly. Refer to ACC-3, "Exploded View".
>> INSPECTION END
11.CHECK INTERMITTENT INCIDENT
Refer to GI-42, "Intermittent Incident".
>> INSPECTION END
Component Inspection
