P2115

P2115-ACCELERATOR PEDAL POSITION SENSOR 1 MINIMUM STOP PERFORMANCE

For a complete wiring diagram, refer to the Wiring Information.

Theory of operation

The Electronic Throttle Control (ETC) system uses two Accelerator Pedal Position (APP) sensors to monitor the accelerator pedal position. The APP sensors 1 and 2 are located within the pedal assembly. Each sensor has a 5-volt reference circuit, a low reference circuit, and a signal circuit. Processors are also used to monitor the ETC system data. The processors are located within the Powertrain Control Module (PCM). Each signal circuit provides processors with a signal voltage proportional to pedal movement. The processors share and monitor data to verify that the indicated APP calculation is correct.

- When Monitored:
With the igniting on. During in-plant testing, the APPS is checked to make sure the minimum and maximum values can be reached. The PCM performs the diagnostic test for this DTC after the diagnostic test for P2166 has passed.

- Set Condition:
APPS 1 has failed to achieve the required minimum value during In-Plant testing. One trip fault and the code will set within 5 seconds. Engine will only idle.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Pre-Diagnostic Troubleshooting Procedure.

1. DTC IS ACTIVE
1. Turn the ignition on.

NOTE: This DTC is set when the APPS values are learned in-plant but do not reach the minimum or maximum voltage range.

NOTE: Diagnose any APPS out of range and 5 volt supply DTCs before continuing.

2. With the scan tool, clear DTCs.
3. Start the engine.
4. With the scan tool, select View DTCs.

Is the status Active for this DTC?

Yes

- Go to 2

No

- Perform the INTERMITTENT CONDITION diagnostic procedure. Intermittent Condition Test.

2. ACCELERATOR PEDAL POSITION SENSOR
1. With a scan tool perform the ETC RELEARN function.
2. With the scan tool, clear DTCs.
3. Start the engine.
4. With the scan tool, select View DTCs.

Is the status Active for this DTC?

Yes

- Replace the Accelerator Pedal Position Sensor. After installation is complete, perform the ETC RELEARN function.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

No

- Test Complete.
