Diagnostic Test

WARNING: This page is about a different variant/trim than selected.

DTC IS ACTIVE
1. Ignition on, engine not running.
2. With the scan tool, erase DTCs in the PCM.
3. Start the engine.
4. Monitor the scan tool for at least two minutes.
5. With the scan tool, select View DTCs.
  Is the status Active for this DTC?
  
  Yes
  - Go To 2.
  No
  - Refer to STANDARD PROCEDURE and perform the INTERMITTENT CONDITION diagnostic procedure.
CHECK THE (G6) OIL PRESSURE SENSOR SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE
1. Turn the ignition off.
2. Disconnect the Oil Pressure Sensor harness connector.
3. Turn the ignition on.
4. Measure the voltage of the (G6) Oil Pressure Sensor Signal circuit at the Oil Pressure Sensor harness connector.
  Does the voltage measure above 5.2 volts?
  
  Yes
  - Repair the (G6) Oil Pressure Sensor Signal circuit for a short to voltage.
  - Refer to STANDARD PROCEDURE and perform the PCM VERIFICATION TEST.
  No
  - Go To 3.
CHECK THE (G6) OIL PRESSURE SENSOR SIGNAL FOR AN OPEN/HIGH RESISTANCE
1. Turn the ignition off.
2. Disconnect the PCM C2 harness connector.
3. Measure the resistance of the (G6) Oil Pressure Sensor Signal between the Oil Pressure Sensor harness connector and the PCM C2 harness connector.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 4.
  No
  - Repair the (G6) Oil Pressure Sensor Signal for an open or high resistance.
  - Refer to STANDARD PROCEDURE and perform the PCM VERIFICATION TEST.
OIL PRESSURE SENSOR
1. Replace the Oil Pressure Sensor in accordance with the service information. Refer to SENSOR, OIL PRESSURE, REMOVAL .
2. Reconnect the PCM C2 harness connector.
3. With the scan tool, erase DTCs in the PCM.
4. Start the engine.
5. Monitor the scan tool for at least two minutes.
6. With the scan tool, select View DTCs.
  Did the DTC return?
  
  Yes
  - Go To 5.
  No
  - Repair complete.
  - Refer to STANDARD PROCEDURE and perform the PCM VERIFICATION TEST.
POWERTRAIN CONTROL MODULE
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Oil Pressure Sensor 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
  - Repair as necessary.
  - Refer to STANDARD PROCEDURE and perform the PCM VERIFICATION TEST.
  No
  - Replace the Powertrain Control Module (PCM) in accordance with the service information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
  - Refer to STANDARD PROCEDURE and perform the PCM VERIFICATION TEST.
