P1125

CIRCUIT DESCRIPTION

The Accelerator Pedal Position (APP) module provides a voltage signal that changes relative to the accelerator pedal position. There are three sensors which are located within the APP module that are scaled differently.


CONDITIONS FOR SETTING THE DTC

The PCM has recognized an intermittent APP fault and there are no other current APP faults stored.


ACTION TAKEN WHEN THE DTC SETS

^ The Service Throttle Soon lamp will not illuminate when one APP DTC sets. The PCM will only illuminate the Service Throttle Soon lamp when multiple APP DTCs set.

^ The PCM records the operating conditions at the time the diagnostic fails. This information stores in the Failure Records.

CONDITIONS FOR CLEARING THE MIL/DTC

A History DTC will clear after forty consecutive warm-up cycles during which the diagnostic does not fail (the coolant temperature has risen 5°C (40°F) from the start up coolant temperature and the engine coolant temperature exceeds 71°C (160°F) during that same ignition cycle).

Use of a Scan tool will clear the DTC codes.


DIAGNOSTIC AIDS

There are no driveability issues associated with the APP module unless a DTC is present. The most likely cause of this DTC are poor connections or the sensor itself. The least likely is a PCM problem.

A DTC P1125 will set along with multiple APP DTCs. All other DTCs should be diagnosed first.

TEST DESCRIPTION
