2001 Chevy Cavalier check oil light comes on when I come to a stop, then turns off when I press gas pedal?!?!?

I have a 2001 Chevy Cavalier.I have checked the oil (on a weekly basis) since buying it,but recently a strange problem has started.Most of the time when the car has been running for 10-15 minutes and I have the air conditioner on the oil light will come on as I'm driving and then come to a complete stop.It will sometimes flash and at other times stay on steadily.As soon as I press the gas to accelerate,the check oil light will go off.What on Earth could cause such a strange thing to happen? I know that I will need new brake pads soon and maybe even a new caliper for the front left brake......could this have anything to do with this??2001 Chevy Cavalier check oil light comes on when I come to a stop, then turns off when I press gas pedal?!?!?
No, it has nothing to do with the brakes,


there is a oil pressure sensor that keeps tabs on the actual pressure the oil pump is pumping.


So if it is coming on when you slow down 1 or more is happening.





1. your oil is to thick or thin to be pumped. changer your oil)


2. The sensor is going bad and when you slow down


the decreased pressure is causeing it to come on too soon.





3. Your oil pump is failing (worn) and is losing pressure when you slow down.





4. your main bearings are worn out and the pressure is not building up the way it should be.





5. the screen on the bottom of the oil pump is almost stopped up with sludge.





When your A/C is on the engine runs hotter and the oil thins out a bit.





The first thing I would do , is simply change my oil and filter and make sure you use the correct oil and filter.





Then change the sensor itself.





these two are the cheapest to do.





The oil pump and main bearings are major.......2001 Chevy Cavalier check oil light comes on when I come to a stop, then turns off when I press gas pedal?!?!?
Raven E has hit it just right that is the perfect answer for this question follow the steps in that order
i don't think your brakes would have anything to do with it, but with a cavalier it wouldn't suprise me. they made those cars to keep the mechanics busy. but it could be you have a gasket problem and the oil is leaking or it's time for a oil change.
If you are certain that the oil level is OK, it is most likely one of these two items.


Most GM cars have a sensor in the oil pan that monitors the oil level in the pan. This sensor may be failing


The second possibility is that the oil pressure sending unit is failing.


It is very unlikely that it has anything to do with your worn brake pads. Just a coincidence.
Your brake pads might ahve something to do with this in the sense that your wiring might be crossing causing the OIL light to go on instead of the brake light, id get your electronics checked out first before looking into oil pumps and such
Could be as simple as the oil is low. by pressing the gas your moving the oil up against the sensor. Or a bad sensor.





Add a little more oil





And don't worry the brakes have no interaction with the oil.
sounds like your oil pump may be going
