1. Measure the resistance between the (K23) APP Signal 1 circuit and the (K854) 5-Volt Supply circuit in the Accelerator Pedal Position Sensor harness connector.
  Is the resistance above 10k Ohms?
  
  Yes
  - Go To 6
  No
  - Repair the (K23) APP Signal 1 circuit for a short to the (K854) 5-Volt Supply circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
CHECK THE (K23) APP SIGNAL 1 CIRCUIT FOR AN OPEN/HIGH RESISTANCE
CAUTION:
Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install the GPEC Diagnostic Adaptor to perform the diagnosis.
1. Connect the (special tool #10436, Adapter, GPEC Diagnostic).
2. Turn the ignition off.
3. Measure the resistance of the (K23) APP Signal 1 circuit between the Accelerator Pedal Position Sensor harness connector and the GPEC Adaptor.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 7
  No
  - Repair the (K23) APP Signal 1 circuit for an open or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
CHECK THE (K167) SENSOR GROUND CIRCUIT FOR AN OPEN/HIGH RESISTANCE
1. Measure the resistance of the (K167) Sensor Ground circuit between the Accelerator Pedal Position Sensor harness connector and the GPEC Adaptor.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 8
  No
  - Repair the (K167) Sensor Ground circuit for an open circuit or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
ACCELERATOR PEDAL POSITION SENSOR

Courtesy of CHRYSLER GROUP, LLC
1. Turn the ignition off.
2. Connect the PCM C1 harness connector.
3. Connect a jumper between the (K167) Sensor Ground circuit and the (K23) APP Signal 1 circuit in the Accelerator Pedal Position Sensor harness connector.
4. Turn the ignition on.
5. With the scan tool, read the Accelerator Pedal Position Sensor signal voltage.
  Is the voltage below 0.1 volts with the jumper in place?
  
  Yes
  - Replace the Accelerator Pedal Position Sensor in accordance with the service information.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 9
POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Accelerator Pedal Position Sensor and the Powertrain Control Module (PCM).
2. Look for any chafed, pierced, pinched, or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals.
4. Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors.
5. Look for the data to change or for the DTC to reset during the wiggle test.
6. Perform any Technical Service Bulletins that may apply.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.
• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
