TEST
3 Turn the ignition off.
Disconnect the PCM harness connectors.
Ignition on, engine not running.
Using a 12-volt test light connected to ground, probe the (G60) Oil Pressure Signal
circuit.
Is the test light brightly illuminated?
Yes → Repair the short to voltage in the (G60) Oil Pressure Signal
→ Go To 4
No
4 Turn the ignition off.
Measure the resistance of the (G60) Oil Pressure Signal circuit from the Oil Pressure
Sensor harness connector to the PCM harness connector.
Is the resistance below 5.0 ohms?
Yes → Go To 5
→ Repair the open in the (G60) Oil Pressure Signal circuit.
No
5 Measure the resistance of the (K900) Sensor ground circuit from the Oil Pressure
Sensor harness connector to the PCM harness connector.
Is the resistance below 5.0 ohms?
Yes → Go To 6
→ Repair the open in the (K900) Sensor ground circuit.
No
