SYMPTOM
P1234 - ACC PEDAL POSITION SENSOR 2 CIRCUIT PLAUSIBILITY

TEST NOTE
This symptom is diagnosed using the test P1222 - ACC PEDAL POSITION SENSOR 1 CKT PLAUSIBILITY.

POSSIBLE CAUSES
- Accelerator pedal position sensor
- ECM - APP sensor 15-volt supply circuit
- Sensor ground open (APP sensor)
- Intermittent condition
- APP sensor 5-volt supply circuit open
- APP sensor signal circuit open
- APP sensor 5-volt supply circuit shorted to sensor ground
- APP sensor signal circuit shorted to ground
- APP sensor 5-volt supply circuit shorted to ground
- Verify APP sensor operation
- APP sensor signal circuit shorted to the sensor ground circuit
- APP sensor 5-volt supply circuit shorted to voltage
- ECM - sensor ground open
- APP sensor circuit shorted to voltage
- APP sensor ground circuit shorted to voltage
- ECM - APP sensor signal circuit
