CHECK THE (K23) APP SENSOR SIGNAL 1 CIRCUIT FOR A SHORT TO THE 5-VOLT SUPPLY CIRCUITS
1. Turn the ignition off.
2. Disconnect the PCM C1 harness connector.
3. Check for continuity between the (K23) APP Sensor Signal 1 circuit and the:
  - (K852) 5-Volt Supply circuit at the APP Sensor harness connector.
  - (K854) 5-Volt Supply circuit at the APP Sensor harness connector.
  Is there continuity between the (K23) APP Sensor Signal 1 circuit and the (K852) 5-Volt Supply circuit or (K854) 5-Volt Supply circuit?
  
  Yes
  - Repair the (K23) APP Sensor Signal 1 circuit for a short to the 5-Volt Supply circuit that showed continuity.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 7
CHECK RELATED PCM AND APP SENSOR CONNECTIONS
1. Disconnect all related in-line harness connections (if equipped).
2. Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
  - Proper connector installation.
  - Damaged connector locks.
  - Corrosion.
  - Other signs of water intrusion.
  - Weather seal damage (if equipped).
  - Brineling on terminals of sensor or harness connector.
  - Bent terminals.
  - Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
  - Terminals that have been pushed back into the connector cavity.
  - Check for spread terminals and verify proper terminal tension.
  Repair any conditions that are found.
  
  NOTE:
  Before reconnecting the harness connectors, clean the terminals with Mopar electrical connector cleaner and apply a light application of dielectric grease to the face of the connector with your finger. This will aid in preventing any future issues with the sensor terminals and connector pins; excessive amounts of dielectric grease can cause damage to the sensor terminals, connector pins, and weather seals.
3. Reconnect all PCM harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
4. Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
5. Reconnect the APP Sensor harness connector. Be certain that the connectors is fully seated and the connector locks are fully engaged.
6. With the scan tool, erase DTCs.
7. Test drive or operate the vehicle in accordance with the when monitored and set conditions.
8. With the scan tool, read DTCs.
  Did the DTC return?
  
  Yes
  - Go To 8
  No
  - The wiring or poor connection problem has been repaired.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
CHECK THE ABILITY OF THE PCM TO READ THE APP SENSOR SIGNAL
1. Turn the ignition off.
2. Disconnect the APP Sensor harness connector.
3. Connect a jumper between the (K23) APP Sensor Signal 1 circuit and the (K167) APP Sensor Ground circuit at the APP Sensor harness connector.
