Diagnostic Test

  1. DTC IS ACTIVE 
    NOTE: Diagnose any CAN - C Communication DTCs before continuing.
    1. Turn the ignition off.
    2. If possible, allow the vehicle to sit with the ignition off for more than 480 minutes in an environment where the temperature is consistent and above - 7°C (19.4°F).
    3. Test drive the vehicle. The vehicle must exceed 48 km/h (30 mph) during the test drive. Do not cycle the ignition off when the test drive is completed.
    4. With a scan tool, select View DTCs.

      Is the status Active or Pending for this DTC?

      Yes 

      • Go to step  3

      No 

      • Go to step  2
  2. AMBIENT AIR TEMPERATURE 
    1. Turn the ignition off.
    2. Allow the vehicle to sit with the ignition off in an environment where the temperature is consistent and above - 7°C (19.4°F) until the engine coolant temperature is equal to ambient temperature.
    3. Turn the ignition on.
    4. With a scan tool, compare the Engine Oil Temperature Sensor value to the AAT, ECT, and IAT sensor values.

      Is the Engine Oil Temperature Sensor value within 10°C (18°F) of the other sensor values?

      Yes 

      No 

      • Go to step  3
  3. (G24) EOT SIGNAL CIRCUIT SHORTED TO VOLTAGE

    1. Turn the ignition off.
    2. Disconnect the Engine Oil Temperature Sensor connector.
    3. Disconnect the Powertrain Control Module (PCM) connector.
    4. Turn the ignition on.
    5. Measure the voltage of the (G24) EOT Signal circuit in the Engine Oil Temperature Sensor harness connector.

      Is there any voltage present?

      Yes 

      No 

      • Go to step  4
  4. (G24) EOT SIGNAL CIRCUIT SHORTED TO GROUND 
    Fig 2: Checking Engine Oil Temperature Sensor Circuit

    1. Turn the ignition off.
    2. Measure the resistance between ground and the (G24) EOT Signal circuit in the Engine Oil Temperature Sensor harness connector.

      Is the resistance above 100 ohms?

      Yes 

      • Go to step  5

      No 

  5. (G24) EOT SIGNAL CIRCUIT SHORTED TO (K915) SENSOR GROUND CIRCUIT 
    Fig 3: Checking Engine Oil Temperature Sensor Circuit

    1. Measure the resistance between the (G24) EOT Signal circuit and the (K915) Sensor Ground circuit in the Engine Oil Temperature Sensor harness connector.

      Is the resistance above 100 ohms?

      Yes 

      • Go to step  6

      No 

  6. (G24) EOT SIGNAL CIRCUIT OPEN OR HIGH RESISTANCE

    NOTE: When checking circuits at the Powertrain Control Module (PCM), be careful not to damage or distort the connector terminals. Improper measurement technique could result in poor pin to terminal contact.
    1. Measure the resistance of the (G24) EOT Signal circuit between the Engine Oil Temperature Sensor harness connector and the Powertrain Control Module (PCM) harness connector.

      Is the resistance below 5.0 ohms?

      Yes 

      • Go to step  7

      No 

  7. (K915) SENSOR GROUND CIRCUIT OPEN OR HIGH RESISTANCE 
    Fig 5: Checking Engine Oil Temperature Sensor Circuit

    NOTE: When checking circuits at the Powertrain Control Module (PCM), be careful not to damage or distort the connector terminals. Improper measurement technique could result in poor pin to terminal contact.
    1. Measure the resistance of the (K915) Sensor Ground circuit between the Engine Oil Temperature Sensor harness connector and the Powertrain Control Module (PCM) harness connector.

      Is the resistance below 5.0 ohms?

      Yes 

      • Go to step  8

      No 

  8. ENGINE OIL TEMPERATURE SENSOR SIGNAL VOLTAGE 
    Fig 6: Checking Engine Oil Temperature Sensor Circuit
    GC0099807Courtesy of CHRYSLER LLC
    1. Turn the ignition off.
    2. Connect the Powertrain Control Module (PCM) connector.
    3. Connect a jumper wire between the (K915) Sensor Ground circuit and the (G24) EOT Signal circuit in the Engine Oil Temperature Sensor harness connector.
    4. Turn the ignition on.
    5. With the scan tool, read the Engine Oil Temperature Sensor signal voltage.

      Is the voltage below 1.0 volt with the jumper wire in place?

      Yes 

      • Go to step  9

      No 

      • Go to step  10
  9. ENGINE OIL TEMPERATURE SENSOR 
    1. Turn the ignition off.
    2. Inspect the wiring and connectors between the Engine Oil Temperature Sensor and the Powertrain Control Module (PCM).
    3. Look for any chafed, pierced, pinched, or partially broken wires.
    4. Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal contact in the related connectors.

      Were any problems found?

      Yes 

      No 

  10. POWERTRAIN CONTROL MODULE (PCM) 
    1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Engine Oil Temperature Sensor 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. Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors.
    5. Look for the data to change or for the DTC to reset during the wiggle test.
    6. Refer to any Technical Service Bulletins that may apply.

      Were any problems found?

      Yes 

      No
