Diagnostic Test

1) OIL PRESSURE SENSOR VOLTAGE ABOVE 4.92 VOLTS
Start the engine.

With a scan tool, read the Oil Pressure Sensor voltage.

Is the voltage above 4.92 volts?

Yes
1. Go To step 2).
No
1. Refer to INTERMITTENT CONDITION .
2. Perform POWERTRAIN VERIFICATION TEST .
2) OIL PRESSURE SENSOR

Turn the ignition off.

Disconnect the Oil Pressure Sensor harness connector.

Connect a jumper wire between the (K302) Oil Pressure Sensor Signal circuit and the (K300) Sensor ground circuit in the Sensor harness connector.

Ignition on, engine not running.

With a scan tool, monitor the Oil Pressure Sensor voltage.

Is the voltage below 1.0 volt with the jumper wire installed?

Yes
1. Replace the Oil Pressure Sensor.
2. Perform BODY VERIFICATION TEST .
No
1. Go To step 3).
  NOTE: Remove the jumper wire before continuing.
3) (K302) OIL PRESSURE SENSOR SIGNAL CIRCUIT SHORTED TO BATTERY VOLTAGE

Is the resistance below 5.0 ohms?

Yes
1. Go To step 7).
No
1. Repair the open in the (K300) Sensor ground circuit.
2. Perform BODY VERIFICATION TEST .
7) BCM
NOTE: Before continuing, check the BCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.

Using the schematics as a guide, inspect the wire harness and connectors. Pay particular attention to all Power and Ground circuits.

Were there any problems found?

Yes
1. Repair as necessary.
2. Perform BODY VERIFICATION TEST .
No
1. Replace and program the Powertrain Control Module per Service Information.
2. Perform POWERTRAIN VERIFICATION TEST .
