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.

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
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION - 6.7L .

1. Turn the ignition off.
2. Disconnect the Inlet Air Temperature/Pressure Sensor harness connector.
  NOTE:
  Check connectors - Clean/repair as necessary.
3. Turn the ignition on.
4. Measure the voltage on the (K615) Inlet Air Temperature Sensor Signal circuit at the Inlet Air Temperature/Pressure Sensor harness connector.
  Does the voltage measure battery voltage?
  
  Yes
  - Repair the (K615) Inlet Air 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 (K615) INLET AIR TEMPERATURE SIGNAL CIRCUIT FOR AN OPEN/HIGH RESISTANCE

1. Disconnect the PCM C1 harness connector.
2. Measure the resistance of the (K615) Inlet Air Temperature Sensor Signal circuit between the Inlet Air Temperature/Pressure Sensor harness connector and the PCM C1 harness connector.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 4.
  No
  - Repair the (K615) Inlet Air 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) INLET AIR TEMPERATURE SENSOR GROUND CIRCUIT FOR AN OPEN/HIGH RESISTANCE

1. Measure the resistance of the (K916) Inlet Air Temperature Sensor Ground circuit between the Inlet Air Temperature/Pressure Sensor harness connector and the PCM C1 harness connector.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 5.
  No
  - Repair the (K916) Inlet Air Temperature Sensor Ground circuit for an open or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST - 6.7L. Refer to POWERTRAIN VERIFICATION TEST - 6.7L .
CHECK THE INLET AIR TEMPERATURE/PRESSURE SENSOR
1. Reconnect the PCM C1 harness connector.
2. Turn the ignition on.
3. With the scan tool, erase DTCs.
4. Turn the ignition off.
5. Connect a jumper between the (K615) Inlet Air Temperature Sensor Signal circuit and the (K916) Inlet Air Temperature/Pressure Sensor Ground circuit at the Inlet Air Temperature/Pressure Sensor harness connector.
6. Turn the ignition on.
7. With the scan tool, read DTCs.
  Did the DTC P1192 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 .
