2G Oil light flickers

[Simonsaysr1]

My oil light flickers on and off at highway use , specifically after I get over 70 mph it fades in and out and becomes solid at 75. Weird its speed based?, during this , my oil pressure is Nominal I have the correct oil level in my pan, and it can turn higher Rpms at lower speeds with no problems? Is this a bad sensor itself? It didn't start happening until I got the car moving again after sitting for a yr

The two oil-related sensors/switches on the oil filter have wimpy little connectors that get old. Check those to make sure they aren't loose. Maybe the wind at 70mph is messing with the connection.

Vegas is correct, and your sender wire for the light might very well be unhooked and grounding at highway speeds against the frame or anything else. They do come off very easy.
Look under the car in front of the drivers wheel and see if you see a wire hanging there doing nothing.

appreciate the ideas, as soon as it stops raining ill go out and check it. i hope it just came loose. is there anyway to use a multimeter to check the output of the sensor while im already there?

There is another thread, I believe, currently posting about the pressure it comes on at. If/when I come across it I will send you a link.

Sounds like bad wiring out cars are over 20 years old and dirt and oil, can get on the spade and cause a bad connection. Also trace the wire as far as you can to looks for wear and tear or cracks on it. Especially if it flickers.

Switch has a 4-7psi resistance to current, at 3 psi it becomes an open circuit and triggers the oil light.

I think you meant it becomes a closed circuit (to ground) to turn the oil light on.

Thank you every one, the spade fell off and it looks rough

I'm glad that's all it was, clean it up and put a new one on. Now you can quit worrying. I put a female spade on mine and gave it just a little "crush" so it would stay on, so far so good.

Totally. Also when I said 4-7 psi I meant 3-9

thank you i will clean up the terminal with a brass brush and crimp on a insulated spade, also thanks for the oil pressure number i feel pretty stupid overlooking something so simple haha

That's what we all come together for. Thanks to everyone for the help!!!
