Diagnostic Test

WARNING: This page is about a different car, the 2012 RAM Pickup. However, it is still accessible from the selected car via links, so may be relevant.

ACTIVE DTC
NOTE:
If there are any 5-Volt supply DTCs present, repair those DTCs before proceeding with this test.
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
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION - 6.7L .

1. Ignition on.
2. Disconnect the Charge Air Cooler Temperature Sensor harness connector.
  NOTE:
  Check connectors - Clean/repair as necessary.
3. With a volt meter connected to ground, measure the voltage of the (K735) Charge Air Cooler Temperature Sensor Signal circuit at the harness connector.
  Is there any voltage present?
  
  Yes
  - Repair the (K735) CAC 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.
CHECK THE (K735) CHARGE AIR COOLER TEMPERATURE SENSOR SIGNAL CIRCUIT FOR AN OPEN/HIGH RESISTANCE

1. Turn the ignition off.
2. Disconnect the PCM C1 harness connector.
3. Measure the resistance of the (K735) CAC Temperature Sensor Signal circuit between the CAC Temperature Sensor harness connector and the PCM C1 harness connector.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 4.
  No
  - Repair the (K735) CAC Temperature Sensor Signal circuit for an open or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST - 6.7L. Refer to POWERTRAIN VERIFICATION TEST - 6.7L .
CHECK THE (K916) SENSOR GROUND CIRCUIT FOR AN OPEN/HIGH RESISTANCE

1. Measure the resistance of the (K916) Sensor Ground circuit between the CAC Temperature Sensor harness connector and the PCM C1 harness connector.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 5.
  No
  - Repair the (K916) Sensor Ground circuit for an open or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST - 6.7L. Refer to POWERTRAIN VERIFICATION TEST - 6.7L .

1. Reconnect the PCM C1 harness connector.
2. Turn the ignition on.
3. With the scan tool, erase DTCs.
4. While monitoring with scan tool, use a jumper wire and connect the (K735) CAC Temperature Sensor Signal circuit to the (K916) CAC Temperature Sensor Return circuit at the CAC harness connector.
  Did the DTC P007C set?
  
  Yes
  - Replace the CAC/Boost 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 .
