Oil Light comes on and then turns off while driving.

Could anyone tell me why my oil light comes on temporarily while driving. I just changed the oil about 700 miles ago and the oil level is still full & looks like new still. I replaced the oil sensor and the problem is still there. Any thoughts, cuz I'm

Maybe.....just maybe.....while you had the pressure sensor out, you should have actually measured the pressure ???

It can be caused by a variety of things from a plugged filter to an oil pump going bad to worn out bearings.

Does it come on at idle and then go off when you speed the engine up ??

At any rate, you probably should NOT drive it until you find out exactly what is going on. If the pressure is down because of a failing pump or a blockage, you might be chewing up your engine.

Yeah really you need to check the oil pressure with an external gauge to know what's really there. Should be 60psi at 1850 rpm using 5W30 oil.

Thumbs up Re: Oil Light comes on and then turns off while driving.

Thanks for the advice.

To answer your question, the oil light only comes on when I'm driving. It comes on & then goes right back out about a second or two later.

Something else I didn't mention is that I just had this engine completely rebuilt due to bad crank bearings. The engine currently has about 1500 miles on it since I put it back in & about 1000 miles since I changed the oil. I also only use 5W30 conventional oil, too.

No reason to mention that; surely it could NOT be a factor..........
<sarcasm off>

You need to get it back to whomever did the lower end rebuild. Something is screwed up with the oil flow......or (pray a bit) that the wires are not making good contact going to the pressure sensor.

If you continue to drive it, you are flirting with disaster.

I have the same problem and have not had any engine work. I also get a "low oil level" warning on the DIC. I changed the oil level sensor and wiring; still both issues. I plan to change the oil pressure sensor tonight; maybe related?

I replaced oil pressure sensor and solved the problem. Oil level alarm on the DIC is still a problem however when I disconnected the battery to replace the pressure sensor the oil level alarm went off for 2 days then came back on. I may short the harness and forget about it.

It would not be a short in the wiring, more likely an open circuit/lose connection. Fail safe design. Otherwise if a wire were to break you could end up driving with low oil and think everything was fine.

This is the problem my friend's is having. Her light comes on momentarily and then she gets the low oil level warning also. Replaced the level sensor, no fix. Does anyone have the schematic for these circuits? Are the level and pressure warnings tied together?

If I can't fix it, it's not broken. But if it's NOT broken I can try to fix it 'til it is.

No, oil level is separate circuit to the ECM from the oil pressure circuits. ECM looks for an open in the circuit.
