Diagnostic Test

WARNING: This page is about a different variant/trim than selected.
  1. CHECK FOR RELATED DTCS 
    1. With the scan tool, check for other DTCs.

      Are there any line pressure sensor or transmission relay output DTCs present also?

      Yes 

      No 

      • Go to step  2
  2. CHECK IF THE DTC IS CURRENT 
    1. With the scan tool, check the Starts Since Set counter for P0869.

      Is the Starts Since Set COUNTER 2 or less?

      Yes 

      • Go to step  3

      No 

      • Go to step  9
  3. CHECK THE PCM AND WIRING 
    1. Turn the ignition off to the lock position.
    2. Remove the Ignition Switch Feed fuse from the TIPM.
      CAUTION: Removal of the Ignition Switch Feed fuse from the TIPM will prevent the vehicle from being started in gear.
      WARNING: The Ignition Switch Feed fuse must be removed from the TIPM. Failure to do so can result in possible serious or fatal injury.
    3. Install the Transmission Simulator 8333A and the Electronic Transmission Adapter kit.
    4. With the Transmission Simulator select the "OFF" position on the "Input/Output Speed" switch.
    5. Ignition on, engine not running.
    6. With the scan tool, monitor the Line Pressure during the following step.
    7. Using the Transmission Simulator, set the rotary switch to each of the three line pressure positions.
      NOTE: All three scan tool Line Pressure readings should be steady and ± 14 kPa or 2.0 psi (0.2 of a volt) of the reading specified on the Transmission Simulator.

      Did the Line Pressure read within ± 14 kPa or 2.0 psi (0.2 of a volt) in all three positions?

      Yes 

      • Go to step  4

      No 

      • Go to step  5
  4. CHECK THE LINE PRESSURE SENSOR CALIBRATION 
    1. Turn the ignition off to the lock position.
    2. Disconnect the Transmission Simulator 8333A and the Electronic Transmission Adapter kit and reconnect all previously disconnected connectors.
    3. Install the Line Pressure Gauge C-3293, 0 to 2000 kPa or 0 to 300 psi in the Line Pressure test port.
    4. Start the engine in park.
    5. Monitor the Line Pressure readings on the scan tool and the pressure gauge.
    6. Compare the Line Pressure readings between the scan tool and the pressure gauge.

      Is the pressure gauge reading within 34 kPa or 5 psi of the scan tool reading?

      Yes 

      No 

  5. CHECK THE (T118) PRESSURE CONTROL LINE PRESSURE CIRCUIT FOR AN OPEN

    1. Turn the ignition off to the lock position.
    2. Disconnect the Transmission Simulator 8333A.
    3. Disconnect the Powertrain Control Module C4 harness connector.
      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 PCM Pinout Box 8815 to perform diagnosis.
    4. Measure the resistance of the (T118) Pressure Control Solenoid Control circuit between the Line Pressure Sensor/Variable Force Solenoid Assembly harness connector and the appropriate terminal of the PCM Pinout Box 8815.

      Is the resistance above 5.0 Ohms?

      Yes 

      No 

      • Go to step  6
  6. CHECK THE (T118) PRESSURE CONTROL LINE PRESSURE CIRCUIT FOR A SHORT TO GROUND 
    Fig 2: Checking Pressure Control Line Pressure Circuit

    1. Measure the resistance between ground and the (T118) Pressure Control Solenoid Control circuit.

      Is the resistance below 5.0 Ohms?

      Yes 

      No 

      • Go to step  7
  7. CHECK THE (F856) 5-VOLT SUPPLY CIRCUIT FOR AN OPEN 
    Fig 3: Checking 5-Volt Supply Circuit
    GC0124129Courtesy of CHRYSLER LLC
    1. Measure the resistance of the (F856) 5-volt Supply circuit between the Line Pressure Sensor/Variable Force Solenoid Assembly harness connector to the appropriate terminal of the PCM Pinout Box 8815.

      Is the resistance above 5.0 Ohms?

      Yes 

      No 

      • Go to step  8
  8. CHECK THE (F856) 5-VOLT SUPPLY CIRCUIT FOR A SHORT TO GROUND 
    Fig 4: Checking 5-Volt Supply Circuit
    GC0124130Courtesy of CHRYSLER LLC
    1. Disconnect the PCM C1 harness connector.
    2. Disconnect the Line Pressure Sensor/Variable Force Solenoid Assembly harness connector.
      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 PCM Pinout Box 8815 to perform diagnosis.
    3. Measure the resistance between ground and the (F856) 5-volt Supply 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. With the scan tool, perform Quick Learn.
      • Perform the 62TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  9. CHECK THE 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
