This just started happening. The check oil light is coming on in my car, but only at idle. The car is idling fine one second, then the check oil light kind of flickers, and rpms drop and the light gets solid, then a second later it goes off and the engine idles fine again. If I pump my brake pedal the light comes on every time I get all the way to the floor. I checked my oil, and its level is fine. What's the problem?

 

Apparently it's because of low oil pressure. Has anyone ever had an oil pump fail on them? Hopefully just cleaning it will work.

 

change the switch...usually just a few dollars and then try a thicker oil....if your using 10-30 try 10-40 etc... this will fix the prob..

 

when it happened to me, I put in some kind of oil treatment to help break up any sludge I may have built up

 

Did it work?

 

Unless it's something worse. The switches go wrong though? where's it located?

 

it may be as simple as an oil pressure sending unit--but when the light is flashing that is the car telling you to turn it off and that it could be in danger.

 

Yah it did man...it was a while ago I would know the actual brand. It may have been the Marvel mystery oil treatment (big red bottle)

 

man im glad you posted this-- im having the EXACT same problem on my 03. my mechanic said that best bet is yeah treatment for buildup and some thicker oil--ive been using 5/30 but i might go with some 10/40 next time. let us know if you come up with anything

update: i just used STP oil treatment and idled for about half an hour. problem solved lol. i will go with thicker oil next time anyways though.

Hmmm anyone have this problem when turbo?

 

sorry to bring life back to an old thread, but the same thing seem to happen to me. when i push down the gas, or have it in gear and step on the break, no oil light, but once its out of gear and i step on the break, the oil light comes on... any input?

this all of a sudden just happened.

 

what kind of oil are you guys running to make this light go on?

 

im sure castrol gtx 5-30 for the winter, and i use castrol gtx 10-30 for the summer...

 

sounds like a short circuit to me
