TEST
1 Start the engine.
With the DRBIII in Sensors, read the Oil Pressure Sensor voltage.
Is the Oil Pressure Sensor voltage below 0.1 of a volt?
Yes → Go To 2
→ Refer to the INTERMITTENT CONDITION Symptom (Diagnos-
No
2 Turn the ignition off.
Disconnect the Oil Pressure Sensor harness connector.
Ignition on, engine not running.
Measure the voltage on the (K7) 5-volt Supply circuit in the Oil Pressure Sensor
harness connector.
Is the voltage between 4.5 to 5.2 volts?
Yes → Go To 3
→ Go To 6
No
3 With the DRBIII in Sensors, read the Oil Pressure Sensor voltage with the Sensor
harness connector still disconnected.
Is the voltage above 4.6 volts?
Yes → Replace the Oil Pressure Sensor.
→ Go To 4
No
