Diagnostic Test

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. DTC IS ACTIVE 
    1. Ignition on, engine not running.
    2. With the scan tool, select View DTCs.

      Is the status Active for this DTC?

      Yes 

      • Go To  2

      No 

      • Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT DTC .
  2. CHECK THE (K352) EXHAUST TEMPERATURE SENSOR 2 SIGNAL CIRCUIT FOR A SHORT TO GROUND 
    1. Turn the ignition off.
    2. Disconnect the Exhaust Gas Temperature Sensor 1/2 harness connector.
    3. Disconnect the PCM C1 harness connector.
    4. Measure the resistance between ground and the (K352) Exhaust Temperature Sensor 2 Signal circuit at the Exhaust Gas Temperature Sensor 1/2 harness connector.

      Is the resistance above 10k Ohms?

      Yes 

      • Go To  3

      No 

      • Repair the (K352) Exhaust Temperature Sensor 2 Signal circuit for a short to ground.
      • Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  3. CHECK FOR THE (K352) EXHAUST TEMPERATURE SENSOR 2 SIGNAL CIRCUIT SHORTED TO THE (K900) SENSOR RETURN CIRCUIT 
    1. Measure the resistance between the (K352) Exhaust Temperature Sensor 2 Signal circuit and the (K900) Sensor Return circuit at the Exhaust Gas Temperature Sensor 1/2 harness connector.

      Is the resistance above 10k Ohms?

      Yes 

      • Go To  4

      No 

      • Repair the (K352) Exhaust Temperature Sensor 2 Signal circuit for a short to the (K900) Sensor Return circuit.
      • Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  4. EXHAUST GAS TEMPERATURE SENSOR 
    1. Reconnect the PCM C1 harness connector.
    2. Reconnect the Exhaust Gas Temperature Sensor 1/2 harness connector.
    3. Turn the ignition on.
    4. With the scan tool, clear DTCs.
    5. Turn the ignition off.
    6. Disconnect the Exhaust Gas Temperature Sensor 1/2 harness connector.
    7. Turn the ignition on.
    8. With the scan tool, select View DTCs.
    9. Monitor the scan tool for at least two minutes.
      NOTE:

      The scan tool should display a P2033-Exhaust Gas Temperature Sensor 1/2 Circuit High DTC as active with the Exhaust Gas Temperature Sensor 1/2 connector unplugged.

      Does the scan tool display the DTC as described above?

      Yes 

      • Replace the Exhaust Gas Temperature Sensor 1/2 in accordance with the service information.
      • Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .

      No 

      • Go To  5
  5. POWERTRAIN CONTROL MODULE 
    1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Exhaust Gas Temperature Sensor 1/2 and the Powertrain Control Module (PCM).
    2. Look for any chafed, pierced, pinched, or partially broken wires.
    3. Look for broken, bent, pushed out or corroded terminals.
    4. Perform any Technical Service Bulletins that may apply.

      Were any problems found?

      Yes 

      No 

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