Diagnostic Test

WARNING: This page is about a different car, the 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. ACTIVE DTC 

    u

    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 for at least five minutes.
    6. With the scan tool, read DTCs.

      Did the DTC reset?

      Yes 

      • Go To  2.

      No 

  2. CHECK THE (K935) EGR OUTLET TEMPERATURE SENSOR SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE

    1. Turn the ignition on.
    2. Disconnect the (K935) EGR Outlet Temperature Sensor harness connector.
      NOTE:

      Check connectors - Clean/repair as necessary.

    3. Measure the voltage of the (K935) EGR Outlet Temperature Sensor Signal circuit at the sensor harness connector.

      Is the voltage reading above 5.1 Volts?

      Yes 

      • Repair the (K935) EGR Outlet Temperature Sensor Signal circuit for a short to voltage.
      • Perform the POWERTRAIN VERIFICATION TEST - 6.7L. Refer to POWERTRAIN VERIFICATION TEST - 6.7L .

      No 

      • Go To  3.
  3. CHECK THE (K935) EGR OUTLET TEMPERATURE SENSOR SIGNAL CIRCUIT FOR AN OPEN/HIGH RESISTANCE

    1. Turn the ignition off.
    2. Disconnect the PCM C1 harness connector.
      NOTE:

      Check connectors - Clean/repair as necessary.

    3. Measure the resistance of the (K935) EGR Outlet Temperature Sensor Signal circuit between the EGR Outlet Temperature Sensor harness connector and the PCM C1 harness connector.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Go To  4.

      No 

      • Repair the (K935) EGR Outlet Temperature Sensor Signal circuit for an open or high resistance.
      • Perform the POWERTRAIN VERIFICATION TEST - 6.7L. Refer to POWERTRAIN VERIFICATION TEST - 6.7L .
  4. CHECK THE (K914) EGR OUTLET TEMPERATURE SENSOR RETURN CIRCUIT FOR AN OPEN/HIGH RESISTANCE

    1. Measure the resistance of the (K914) EGR Outlet Temperature Sensor Return circuit between the EGR Outlet Temperature Sensor harness connector and the PCM C1 harness connector.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Go To  5.

      No 

      • Repair the (K914) EGR Outlet Temperature Sensor Return circuit for an open or high resistance.
      • Perform the POWERTRAIN VERIFICATION TEST - 6.7L. Refer to POWERTRAIN VERIFICATION TEST - 6.7L .
  5. CHECK THE RESISTANCE OF THE EXHAUST GAS RECIRCULATION OUTLET TEMPERATURE SENSOR 
    1. Measure the resistance between the (K935) EGR Outlet Temperature Sensor Signal circuit and the (K914) EGR Outlet Temperature Sensor Return circuit at the EGR Outlet Temperature Sensor.

      Is the resistance between 200 Ohms and 2.4M Ohms?

      Yes 

      • Replace the Powertrain Control Module in accordance with the service information.
      • Perform the POWERTRAIN VERIFICATION TEST - 6.7L. Refer to POWERTRAIN VERIFICATION TEST - 6.7L .

      No 

      • Replace the EGR Outlet Temperature Sensor in accordance with the service information.
      • Perform the POWERTRAIN VERIFICATION TEST - 6.7L. Refer to POWERTRAIN VERIFICATION TEST - 6.7L .
