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 
    NOTE:

    If there are any 5-Volt supply DTCs present, repair those DTCs before proceeding.

    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?

      Yes 

      • Go To  2.

      No 

  2. CHECK THE (K615) INLET AIR TEMPERATURE SENSOR SIGNAL CIRCUIT FOR A SHORT TO GROUND

    1. Turn the ignition off.
    2. Disconnect the Inlet Air Temperature/Pressure Sensor harness connector.
    3. Disconnect the PCM C1 harness connector.
    4. Measure the resistance between ground and the (K615) Inlet Air Temperature/Pressure Sensor Signal circuit at the Inlet Air Temperature/Pressure Sensor harness connector.

      Is the resistance below 10k Ohms?

      Yes 

      • Repair the (K615) Inlet Air Temperature Sensor Signal circuit for a short to ground.
      • Perform the POWERTRAIN VERIFICATION TEST - 6.7L. Refer to POWERTRAIN VERIFICATION TEST - 6.7L .

      No 

      • Go To  3.
  3. CHECK FOR THE (K615) INLET AIR TEMPERATURE SENSOR SIGNAL CIRCUIT SHORTED TO (K916) SENSOR GROUND

    1. Measure the resistance between the (K615) Inlet Air Temperature Sensor Signal circuit and the (K916) Sensor Ground circuit at the Inlet Air Temperature/Pressure Sensor harness connector.

      Is the resistance below 10k Ohms?

      Yes 

      • Repair the short between the (K615) Inlet Air Temperature Sensor Signal circuit and the (K916) Sensor Ground circuit.
      • Perform the POWERTRAIN VERIFICATION TEST - 6.7L. Refer to POWERTRAIN VERIFICATION TEST - 6.7L .

      No 

      • Go To  4.
  4. CHECK THE INLET AIR TEMP SENSOR 
    1. Reconnect the Inlet Air Temperature/Pressure Sensor harness connector.
    2. Reconnect the PCM C1 harness connector.
    3. Turn the ignition on.
    4. With the scan tool, erase DTCs.
    5. While monitoring the scan tool, disconnect the Inlet Air Temperature/Pressure Sensor harness connector.

      Did the DTC P1193 set?

      Yes 

      • Replace the Inlet Air Temperature/Pressure Sensor in accordance with the service information.
      • Perform the POWERTRAIN VERIFICATION TEST - 6.7L. Refer to POWERTRAIN VERIFICATION TEST - 6.7L .

      No 

      • 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 .
