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.

CHECK TO SEE IF DTC IS CURRENT
1. With the scan tool, Check the Starts Since Set counter for P0935.
  NOTE:
  This counter only applies to the last DTC set.
  
  Is the Starts Since Set counter 2 or less?
  
  Yes
  - Go To 2
  No
  - Go To 6
CHECK THE PCM AND WIRING
1. Turn the ignition off to the lock position.
2. Remove the Starter Relay.
  CAUTION:
  Removal of the Starter Relay will prevent the vehicle from being started in gear.
  
  WARNING:
  The Starter Relay must be removed from the PDC. Failure to do so may result in possible serious or fatal injury.
  
  NOTE:
  Failure to remove the Starter Relay can cause a Transmission - No Response condition.
3. Install the Transmission Simulator (special tool #8333B, Simulator, Transmission) and the Electronic Transmission Adapter kit.
4. Ignition on, engine not running.
5. With the scan tool, monitor the Line Pressure.
6. 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 of the reading specified on the Transmission Simulator.
  
  Did the Line Pressure read within ± 14 kPa or 2.0 psi in all three positions?
  
  Yes
  - Replace the Line Pressure Sensor in accordance with the Service Information. Refer to SENSOR, PRESSURE CONTROL, REMOVAL .
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 3
CHECK THE (T853-DIESEL) (K900-GAS) SENSOR GROUND CIRCUIT FOR AN OPEN
1. Turn the ignition off to the lock position.
2. Disconnect the Transmission Simulator (special tool #8333B, Simulator, Transmission) and the Electronic Transmission Adapter kit.
3. Disconnect the PCM C1 harness connector.
4. Measure the resistance of the (T853 or K900) Sensor Ground circuit from the Transmission Solenoid/TRS Assembly harness connector to the appropriate terminal of the PCM C1 harness connector.
  Is the resistance above 5.0 Ohms?
  
  Yes
  - Repair the (T853 or K900) Sensor Ground circuit for an open.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 4
CHECK THE (T38) LINE PRESSURE SIGNAL CIRCUIT FOR AN OPEN

1. Disconnect the PCM C1 harness connector.
2. Measure the resistance of the (T38) Line Pressure Signal circuit from the Transmission Solenoid/TRS Assembly harness connector to the appropriate terminal of the PCM C1 harness connector.
  Is the resistance above 5.0 Ohms?
  
  Yes
  - Repair the (T38) Line Pressure Signal circuit for an open.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 5
CHECK THE (T38) LINE PRESSURE SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE

1. Remove the PCM/TCM relay and with a fused jumper wire, jumper the Transmission Control Output to B(+).
2. Ignition on, engine not running.
3. Measure the voltage of the (T38) Line Pressure Sensor Signal circuit.
  Is the voltage above 5.5 volts?
  
  Yes
  - Repair the (T38) Line Pressure Signal circuit for a short to voltage.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  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 62TE TRANSMISSION VERIFICATION TEST .
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
  - Repair as necessary.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Test Complete.
