WARNING: This page is about a different car, the 2014 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.
  1. DTC IS ACTIVE 
    1. Ignition on, engine not running.
    2. With the scan tool, erase DTCs in the PCM.
    3. Start the engine.
    4. Monitor the scan tool for at least two minutes.
    5. With the scan tool, select View DTCs.

      Is the status Active for this DTC?

      • Go To  2

      No 

      • Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT DTC .
  2. CHECK THE (G6) OIL PRESSURE SWITCH SIGNAL CIRCUIT FOR A SHORT TO GROUND 
    1. Turn the ignition off.
    2. Disconnect the Oil Pressure Switch harness connector.
    3. Disconnect the PCM C2 harness connector.
    4. Measure the resistance between ground and the (G6) Oil Pressure Switch Signal circuit at the Oil Pressure Switch harness connector.

      Does the resistance measure above 10k Ohms?

      Yes 

      • Repair the (G6) Oil Pressure Switch Signal circuit for a short to ground.
      • Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .

      No 

      • Go To  3
  3. CHECK THE (G6) OIL PRESSURE SWITCH SIGNAL FOR AN OPEN/HIGH RESISTANCE 
    1. Measure the resistance of the (G6) Oil Pressure Switch Signal between the Oil Pressure Switch harness connector and the PCM C2 harness connector.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Go To  4

      No 

      • Repair the (G6) Oil Pressure Switch Signal for an open or high resistance.
      • Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  4. OIL PRESSURE SWITCH 
    1. Replace the Oil Pressure Switch in accordance with the service information.
    2. Reconnect the PCM C2 harness connector.
    3. With the scan tool, erase DTCs in the PCM.
    4. Start the engine.
    5. Monitor the scan tool for at least two minutes.
    6. With the scan tool, select View DTCs.

      Did the DTC return?

      Yes 

      • Go To  5

      No 

  5. POWERTRAIN CONTROL MODULE 
    1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Oil Pressure Switch 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.
    4. Perform any Technical Service Bulletins that may apply.

      Were any problems found?

      Yes 

      No 

      • Replace the Powertrain Control Module (PCM) in accordance with the service information. Refer to REMOVAL .
      • Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
