Diagnostic Test

WARNING: This page is about a different car, the 2016 Dodge Journey and 2015 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK TO SEE IF DTC P0883 IS CURRENT 
    1. With the scan tool, check the Starts Since Set counter.
      NOTE:

      This counter only applies to the last DTC set.

      Is the Starts Since Set counter set to 0?

      Yes 

      • Go To  2

      No 

      • Go To  8
  2. CHECK PCM/TCM RELAY 
    1. Install substitute PCM/TCM Relay.
    2. Ignition on, engine not running.
    3. With the scan tool, check the Starts Since Set counter.

      Is the Starts Since Set counter set to 0?

      Yes 

      • Go To  3

      No 

  3. (T16) TRANSMISSION OUTPUT CIRCUIT SHORT TO VOLTAGE 
    1. Turn the ignition off to the lock position.
    2. Remove the PCM/TCM Relay form the PDC.
    3. Disconnect the PCM C2 harness connector.
    4. Ignition on, engine not running.
    5. Measure the voltage of the (T16) Transmission Control Output circuit(s) at the PCM C2 harness connector.

      Is the voltage above 0.5 volts?

      Yes 

      • Go To  4

      No 

      • Go To  7
  4. CHECK THE TRANSMISSION SOLENOID/PRESSURE SWITCH ASSEMBLY 
    1. Turn the ignition off to the lock position.
    2. Disconnect the Transmission Solenoid/Pressure Switch Assembly harness connector.
    3. Ignition on, engine not running.
    4. Measure the voltage of the (T16) Transmission Control Output circuit(s).

      Is the voltage above 0.5 volts?

      Yes 

      • Go To  5

      No 

  5. CHECK THE TRANSMISSION RANGE SENSOR 
    1. Turn the ignition off to the lock position.
    2. Disconnect the Transmission Range Sensor (TRS) harness connector.
    3. Ignition on, engine not running.
    4. Measure the voltage of the (T16) Transmission Control Output circuit(s).

      Is the voltage above 0.5 volts?

      Yes 

      • Go To  6

      No 

  6. CHECK THE LINE PRESSURE SENSOR/VARIABLE FORCE SOLENOID ASSEMBLY 
    1. Turn the ignition off to the lock position.
    2. Disconnect the Line Pressure/Variable Force Solenoid Assembly harness connector.
    3. Ignition on, engine not running.
    4. Measure the voltage of the (T16) Transmission Control Output circuit(s).

      Is the voltage above 0.5 volts?

      Yes 

      No 

  7. CHECK THE (T15) TRANSMISSION CONTROL CIRCUIT FOR A SHORT TO GROUND 
    1. Turn the ignition off to the lock position.
    2. Disconnect the PCM C2 harness connector.
    3. Measure the resistance between ground and the (T15) Transmission Control circuit.

      Is the resistance below 5.0 Ohms?

      Yes 

      No 

      • Using the schematics as a guide, check the Powertrain Control Module (PCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace and program the PCM in accordance with the Service Information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL . With the scan tool, perform Quick Learn.
      • Perform the TRANSMISSION VERIFICATION TEST. Refer to 40/41TE TRANSMISSION VERIFICATION TEST  .
  8. CHECK WIRING AND CONNECTORS 
    1. The conditions necessary to set this DTC are not present at this time.
    2. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
    3. Wiggle the wires while checking for shorted and open circuits.
    4. With the scan tool, check the Event Data to help identify the conditions in which the DTC was set.

      Where there any problems found?

      Yes 

      No
