Diagnostic Test

WARNING: This page is about a different car, the 2016 Dodge Durango. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK FOR AN ACTIVE DTC 
    NOTE:

    Make sure that the engine oil is at the proper level. Also, check the customers oil change history to ensure that the oil is being changed at the correct intervals and that the proper oil viscosity is being used.

    1. Start the engine and allow it to reach normal operating temperature.
      WARNING:

      When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing. Failure to follow these instructions may result in possible serious or fatal injury.

      NOTE:

      Diagnose and repair any system voltage or 5-Volt Reference DTCs before continuing with this test.

      Is the DTC active or pending?

      Yes 

      • Go To  2

      No 

  2. ENGINE OIL/ENGINE MECHANICAL 
    NOTE:

    The following items must be considered before determining the cause of this DTC. Failure to do so may lead to misdiagnosis. For the VCT to enable the oil pressure has to be approximately 42 psi. For the VCT to remain enabled the engine oil pressure can not drop below 31 psi. When checking the engine oil pressure use a mechanical gauge.

    • OIL FILTER INSTALLED INCORRECTLY OR DOES NOT MEET OEM SPECIFICATION
    • ENGINE MECHANICAL TOLERANCES OUT OF SPECIFICATION
    • ENGINE OIL PRESSURE OUT OF SPECIFICATION
    • LOW ENGINE OIL
    • OIL DIRTY OR DETERIORATED (Lack of scheduled oil changes)
    • CORRECT VISCOSITY
    • ENGINE OIL CONTAMINATED (i.e., coolant and/or fuel)

    1. If any of the above conditions are found, repair as necessary.

      Were any of the above conditions present?

      Yes 

      No 

      • Go To  3
  3. ENGINE OIL PRESSURE SENSOR

    1. Turn the ignition off.
    2. Connect the PCM C2 harness connector.
    3. Turn the ignition on.
    4. With a scan tool, monitor the Engine Oil Pressure Sensor voltage.
    5. Connect a jumper between the (K900) Sensor Ground circuit and the (G6) Engine Oil Pressure Signal circuit.
      NOTE:

      Engine Oil Pressure voltage should change from approximately 4.5 volts to less than 0.2 volts.

      Is the voltage reading within the listed specification when the jumper wire is installed?

      Yes 

      • Verify that there is good pin to terminal contact in the Engine Oil Pressure Sensor and Powertrain Control Module connectors. If OK, replace the Engine Oil Pressure Sensor. Refer to SENSOR, OIL PRESSURE, REMOVAL .
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

      No 

      • Go To  4
        NOTE:

        Remove the jumper before continuing.

  4. CHECK FOR EXCESSIVE RESISTANCE IN THE (G6) ENGINE OIL PRESSURE SIGNAL CIRCUIT 
    1. Turn the ignition off.
    2. Disconnect the PCM C2 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 GPEC Diagnostic Adaptor to perform the diagnosis.

    3. Connect the (special tool #10436, Adapter, GPEC Diagnostic).
    4. Measure the resistance of the (G6) Engine Oil Pressure Signal circuit from the Engine Oil Pressure Sensor harness connector to the GPEC Adaptor.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Go To  5

      No 

      • Repair the excessive resistance in the (G6) Engine Oil Pressure Signal circuit.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  5. CHECK THE (G6) ENGINE OIL PRESSURE SIGNAL CIRCUIT FOR A SHORT TO GROUND 
    Fig 2: Checking Engine Oil Pressure Signal Circuit For Short To Ground
    GC0149088Courtesy of CHRYSLER GROUP, LLC
    1. Measure the resistance between ground and the (G6) Engine Oil Pressure Signal circuit in the Engine Oil Pressure Sensor harness connector.

      Is the resistance above 10k Ohms?

      Yes 

      • Go To  6

      No 

      • Repair the (G6) Engine Oil Pressure Signal circuit for a short to ground.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  6. CHECK FOR EXCESSIVE RESISTANCE IN THE (F855) 5-VOLT SUPPLY CIRCUIT 
    1. Measure the resistance of the (F855) 5-Volt Supply circuit from the Engine Oil Pressure Sensor harness connector to the GPEC Adaptor.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Go To  7

      No 

      • Repair the excessive resistance in the (F855) 5-Volt Supply circuit.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  7. CHECK THE (F855) 5-VOLT SUPPLY FOR A SHORT TO GROUND
