For 1990-2009 cars only
Circuit Description
The accelerator pedal position (APP) module provides a voltage signal that changes relative to accelerator pedal position. There are three sensors located within the APP module that are scaled differently.
Conditions for Running
The ignition switch is in the ON position.
Conditions for Setting the DTC
PCM has recognized multiple APP faults.
Action Taken When the DTC Sets
| • | Vehicle will operate at limited power. |
| • | The PCM will not illuminate the malfunction indicator lamp (MIL). |
| • | The PCM records the operating conditions at the time the diagnostic fails. This information is stored in the Failure Records. |
Conditions for Clearing the MIL/DTC
| • | A History DTC clears after forty consecutive warm-up cycles, if this or any other emission related diagnostic does not report any failures. |
| • | Use of a scan tool |
Diagnostic Aids
Important: Remove any debris from the PCm module connector surfaces before servicing the PCM module. Inspect the PCM module connector gaskets when diagnosing/replacing the module. Ensure that the gaskets are installed correctly. The gaskets prevent contaminate intrusion into the PCM module.
A DTC P1125 will set along with multiple APP DTCs. All other DTCs should be diagnosis first.
