Remove oil sending unit and install a mechanical gauge to actually test oil pressure Low pressure may be caused be worn internal engine parts (bearings) or a weak oil pump
could be a loose connection on oil temp or pressure switch.
Deville Dalton goes by Alley.
When you have oil pressure, the light goes out, barring a malfunctioning pressure sender.
In the 2002 deville takes 7.5 quarts
When my tire pressure light goes on in my 2006 rav4, I add air to the spare and it goes off.
Yes. The light means that one of the tires is not reading correctly. Either from improper pressure or a sensor problem.
The most common reason for the oil pressure light to come on when your vehicle is idling, is low oil. Check your engine oil and make sure the oil is up to the full mark on the dipstick.
low tire pressure
Properly inflate tires, drive car, light goes out.
As the temperature goes up the oil pressure goes down because the oil thins out. It is possible that the increasing temperature which causes the 'temp' light to come on can thin the oil enough to cause the 'oil' light to come on also.
If the oil pressure light goes on in a MK4 Golf Turbo make sure the oil used is rated from VW. Putting the wrong type of oil in the Golf Turbo continuously can cause the oil pressure warning light to go on.
If there a light on the instrument panel that says fuel cutoff relay that's on, then behind the passenger kick panel is a relay with a red button, push it and if it clicks and the fuel cutoff relay light goes off and you have fuel pressure you should be alright. If the relay doesnt click and the fuel cutoff relay light stays on then you probably have a bad relay. If the light goes out and you don't have any or enough fuel pressure then you need a new fuel pump or fuel filter and or both. also if you don't have enough fuel pressure you could have a bad fuel pressure regulator which is on the back of the engine. If you get the light to go off and it runs good then you have solved the problem. If the light goes out and it starts but does not run very well you should check the fuel pressure. Hope this helps.
