Diagnostic Test

CHECK FOR AN ACTIVE DTC
1. Turn the ignition on.
2. With the scan tool, read and record DTCs and Freeze Frame data on the repair order.
  Is the DTC active or pending?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
CHECK FOR HIGH RESISTANCE IN THE (K932) EGR TEMP SENSOR SIGNAL CIRCUIT
1. Turn the ignition off.
2. Disconnect the EGR Temperature Sensor harness connector.
3. Disconnect the PCM C2 harness connector.
4. Measure the resistance of the (K932) EGR Temp Sensor Signal circuit between the EGR Temperature Sensor harness connector and the PCM C2 harness connector.
  Is the resistance below 3.0 Ohms?
  
  Yes
  - Go To 3
  No
  - Repair the high resistance in the (K932) EGR Temp Sensor Signal circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
CHECK FOR HIGH RESISTANCE IN THE (K916) SENSOR GROUND CIRCUIT
1. Measure the resistance of the (K916) Sensor Ground circuit between the IAT 2 Sensor harness connector and the PCM C2 harness connector.
  Is the resistance below 3.0 Ohms?
  
  Yes
  - Replace the EGR Temperature Sensor in accordance with the Service Information.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Repair the high resistance in the (K916) Sensor Ground circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
