Oil pressure light when idling

[FJCOURTS]

Just came back from a ride and my oil pressure light comes on at idle. Manual and electronic oil levels say that there is adequate oil. Do I have a serious problem? Thanks

I think you need to have it checked - to be safe.

In total, 2 wires are connected to the sensor for the oil pressure indicator. The wire with the terminal designation "WC" (warning contact) is connected to the oil pressure switch which connects ground to the instrument cluster in the case of a stationary engine or low oil pressure and thereby actuates the warning light. A display warning is also emitted in the instrument cluster at the same time if the engine is running and the oil pressure is low.

I suggest you find a dealer or independent shop with a PST2 or PIWIS and have them check the instrument cluster for errors. Then have them do a cluster drive link test to identify the failed part/connection.

If it is not one of the above mentioned items then you could have a serious engine problem.

Hi

I have a 2000 cab with the same problem, oil light comes on at idle when warm and oil pressure is under 1 bar at idle.

I changed oil (15-50 Mobile 1) no change

How did you solve your problem

Thanks

John
