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. ACTIVE DTC 
    1. Turn the ignition on.
    2. With the scan tool, record all Freeze frame data.
    3. With the scan tool, erase DTCs.
    4. Turn the ignition off for 75 seconds.
    5. Turn the ignition on.
    6. With the scan tool, read DTCs.

      Did the DTC reset?

      • Go To  2

      No 

      • Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT DTC .
  2. CHECK THE (K935) EGR OUTLET TEMPERATURE SENSOR SIGNAL CIRCUIT FOR A SHORT TO GROUND 
    1. Turn the ignition off.
    2. Disconnect the PCM C2 harness connector.
    3. Disconnect the EGR Outlet Temperature Sensor harness connector.
      NOTE:

      Check connectors - Clean/repair as necessary.

    4. Measure the resistance between ground and the (K935) EGR Outlet Temperature Sensor Signal circuit at the EGR Outlet Temperature Sensor harness connector.

      Is the resistance above 10k Ohms?

      Yes 

      • Go To  3

      No 

      • Repair the (K935) EGR Outlet Temperature Sensor Signal circuit for a short to ground.
      • Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  3. CHECK THE (K935) EGR OUTLET TEMPERATURE SENSOR SIGNAL CIRCUIT FOR A SHORT TO THE (K915) SENSOR GROUND CIRCUIT 
    1. Measure the resistance between the (K935) EGR Outlet Temperature Sensor Signal circuit and the (K915) EGR Outlet Temperature Sensor Return circuit at the EGR Outlet Temperature Sensor harness connector.

      Is the resistance above 10k Ohms?

      Yes 

      • Go To  4

      No 

      • Repair the short between the (K935) EGR Outlet Temperature Sensor Signal circuit and the (K915) EGR Outlet Temperature Sensor Return circuit.
      • Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  4. EGR OUTLET TEMPERATURE SENSOR 
    1. Replace the EGR Outlet Temperature Sensor in accordance with the service information.
    2. Reconnect the PCM C2 harness connector.
    3. Reconnect the EGR Outlet Temperature Sensor harness connector.
    4. Turn the ignition on.
    5. With the scan tool, erase PCM DTCs.
    6. Perform several ignition key cycles leaving the ignition on for at least 10 seconds per cycle.
    7. Start the engine and let it run for two minutes.
    8. With the scan tool, read PCM DTCs.

      Does the scan tool display this DTC?

      Yes 

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