Diagnostic Test

WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

ACTIVE DTC
NOTE:
Check the TCM for DTCs, if P0706 is set in the TCM diagnose the TCM code before continuing.
1. Ignition on, engine not running.
2. While moving the gear selector through all gear positions (Park to 1 and back to Park).
3. Using a scan tool, select View DTCs.
  Is the DTC Active at this time?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
TRS (T41) SENSE (P/N SENSE) CIRCUIT OPEN
1. Turn the ignition off.
2. Disconnect the C3 PCM harness connector.
3. Disconnect the Transmission Range Sensor harness connector.
4. Measure the resistance of the TRS (T41) Sense (P/N Sense) circuit from the TRS harness connector to the appropriate terminal of the PCM
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 3
  No
  - Repair the open in the TRS (T41) Sense (P/N Sense) circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
TRS (T41) SIGNAL CIRCUIT SHORTED TO GROUND
1. Measure the resistance between ground and the TRS (T41) Sense (P/N Sense) circuit at the TRS harness connector.
  Is the resistance above 100k Ohms?
  
  Yes
  - Go To 4
  No
  - Repair the short to ground in the TRS (T41) Sense (P/N Sense) circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
TRANSMISSION RANGE SENSOR
1. Measure the resistance between ground and the (T41) TRS Sense (P/N Sense) circuit while moving the gear selector through each gear in the TRS connector.
  NOTE:
  The circuit is grounded in Park and Neutral and open in the other positions.
  
  Did the resistance change from above 100k Ohms (open) to below 10.0 Ohms (grounded)?
  
  Yes
  - Go To 5
  No
  - Verify that there is good pin to terminal contact in the TRS and Powertrain Control Module connectors. Replace the Transmission Range Sensor.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Transmission Range 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. Verify that there is good pin to terminal contact in the TRS and Powertrain Control Module connectors.
4. Perform any Technical Service Bulletins that may apply.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Replace and program the Powertrain Control Module in accordance with the Service Information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
