P2128 | APP SEN 2/CIRC (Throttle/Pedal position sensor/switch “E” circuit high) | An excessively high voltage from the APP sensor 2 is sent to ECM. |
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 8 V at idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
Is DTC detected? YES >> Proceed to EC-435, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK APP SENSOR 2 POWER SUPPLY
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK SENSOR POWER SUPPLY 2 CIRCUIT
Check sensor power supply 2 circuit. Refer to EC-444, "Diagnosis Procedure".
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 2 GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK APP SENSOR 2 INPUT SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK APP SENSOR
Check APP sensor. Refer to EC-436, "Component Inspection (APP Sensor)".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace accelerator pedal assembly. Refer to ACC-3, "Removal and Installation".
Component Inspection (APP Sensor)
1.CHECK ACCELERATOR PEDAL POSITION SENSOR
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace accelerator pedal assembly. Refer to ACC-3, "Removal and Installation".
