Oil Pressure Sensor: Description and Operation

Engine Oil Pressure Switch:

The PCM monitors the engine oil pressure switch (1) signal to determine if the engine oil pressure is OK. If the PCM determines that a low oil pressure condition exists, the PCM will communicate the information over the Class II circuit to the P cluster and it will illuminate the indicator lamp or initiate a message.




The low oil pressure message may not appear if other messages are being commanded, such as the rear deck lid, driver or passenger doors ajar. Ensure that all doors and compartment lids are completely closed.
