Diagnostic Test

WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
  1. 1)  CHECK TO SEE IF DTC IS CURRENT 

    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 

    1. Go To step  2).

    No 

    1. Go To step  6).
  2. 2)  CHECK THE PCM AND WIRING 

    Turn the ignition off to the lock position.

    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 can result in personal injury or death.
    NOTE: Removal of the Starter Relay is to prevent a Transmission, NO RESPONSE, condition and disable the starter.

    Install the Transmission Simulator, Miller tool #8333 and the Electronic Transmission Adapter kit.

    Ignition on, engine not running.

    With the scan tool, monitor the Line Pressure.

    Using the Transmission Simulator, set the rotary switch to each of the 3 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 

    1. Replace the Line Pressure Sensor per the Service Information.
    2. Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1  

    No 

    1. Go To step  3).
  3. 3)  CHECK THE (K900) SENSOR GROUND CIRCUIT FOR AN OPEN

    Turn the ignition off to the lock position.

    Disconnect the Transmission Simulator, Miller tool #8333 and the Electronic Transmission Adapter kit.

    Disconnect the PCM C2 harness connector and connect Miller tool #8815.

    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 Miller tool #8815 to perform diagnosis.

    Measure the resistance of the (K900) Sensor Ground circuit from the Line Pressure Sensor/Variable Force Solenoid Assembly harness connector to the appropriate terminal of Miller tool #8815.

    Is the resistance above 5.0 ohms? 

    Yes 

    1. Repair the (K900) Sensor Ground circuit for an open.
    2. Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1  

    No 

    1. Go To step  4).
  4. 4)  CHECK THE (T38) LINE PRESSURE SENSOR SIGNAL CIRCUIT FOR AN OPEN 
    Fig 2: Checking Line Pressure Sensor Signal Circuit

    Disconnect the PCM C4 harness connector and connect Miller tool #8815.

    Measure the resistance of the (T38) Line Pressure Sensor Signal circuit from the Line Pressure Sensor/Variable Force Solenoid Assembly harness connector to the appropriate terminal of Miller tool #8815.

    Is the resistance above 5.0 ohms? 

    Yes 

    1. Repair the (T38) Line Pressure Sensor Signal circuit for an open.
    2. Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1  

    No 

    1. Go To step  5).
  5. 5)  CHECK THE (T38) LINE PRESSURE SENSOR SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE 
    Fig 3: Checking Line Pressure Sensor Signal Circuit
    GC0039383Courtesy of DAIMLERCHRYSLER CORP.

    Remove the Transmission Control Relay.

    Connect a jumper wire between the (A104) Fused B(+) circuit and the (T16) Transmission Control Relay Output circuit in the Transmission Control Relay connector.

    Ignition on, engine not running.

    Measure the voltage of the (T38) Line Pressure Sensor Signal circuit.

    Is the voltage above 5.5 volts? 

    Yes 

    1. Repair the (T38) Line Pressure Sensor Signal circuit for a short to voltage.
    2. Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1  

    No 

    1. 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 the PCM per the Service Information. With the scan tool, perform QUICK LEARN.
    2. Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1  
  6. 6)  CHECK WIRING AND CONNECTORS 

    The conditions necessary to set this DTC are not present at this time.

    Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.

    Wiggle the wires while checking for shorted and open circuits.

    With the scan tool, check the DTC EVENT DATA to help identify the conditions in which the DTC was set.

    Where there any problems found? 

    Yes 

    1. Repair as necessary.
    2. Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1  

    No 

    1. Test Complete.
