5.

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 ACCELERATOR PEDAL POSITION SENSOR GROUND CIRCUIT

1.

Check the continuity between accelerator pedal position sensor 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 INTERMITTENT INCIDENT 

Check intermittent incident. Refer to 

GI-41, "Intermittent Incident"

.

Is the inspection result normal?

YES

>> Replace accelerator pedal position sensor.

NO

>> Repair or replace error-detected parts.
