If the oil light is working and is off with engine running, then you have oil pressure. To determine how much pressure, you need a pressure Gage.
If you have oil pressure it is working.
replace oil sensor unit
My guess is low or no oil pressure.
Two things to check: Is there any oil in the engine? Is the oil pump working? If you remove the dip stick while the engine is running you should get oil all over you if the pump is working.
Oil pressure test.
If it is not working you have no oil pressure and the oil light will come on or the oil pressure gauge will drop to 0. You will also hear engine noise, as in, pecking, or knocking. Engine will also overheat very quickly.
Oil pressure ( Minimum ) 1000 RPMs 6 LBS 2000 RPMs 18 LBS 4000 RPMs 24 LBS It must have at least that much oil pressure at these different RPMs to LUBE the engine. If it has 80 LBS are more then the oil pump check valve is not working correctly
Oil pressure should be 40 to 50 psi
the pressure
Turn off your vehicle, turn key to "run" press in on accelerator 4times in 3 seconds then turn the vehicle back on. should be off :) ---------------- In my case, was bad oil filter! try to change your oil and filter before making expensive tryout repairs!
I have no number on panel when icon checks oil pressure . please guide me what is problem
