Could be the oil pump, but before you get to that, whens the last time you had you oil changed? is it the right type? was the filter changed to? if the oil is to thick for your engine, the pump could be having a problem pushing it. If its dirty, same thing applies. Next time you change your oil, be sure to use a full synthetic. its a superior oil all around.

    I don't want to immediately tell you the filter is why your having these problems, as it could be a number of things. But i will tell you it is best to change your filter at every oil change. Whats the point of putting clean oil in a dirty filter? Unless it causes problems, i would say drive on it until your next oil change, and be sure to have a new filter put in. If you still have the same problem, then move on from there. But for now there is no need to replace an oil pump if its something that's handled routinely anyway.

SOURCE: 2002 Mitsubishi Lancer Oil Light at Low RPMS.

I had the same exact problem over the weekend. We decided to go cheap first and replace the Oil Pressure Switch. It's like $6.00 at Auto Zone here in Texas. (don't know if you are from the states). It ended up being the switch. It's located right by the oil filter and it's very easy to change. Just make sure you have a wrench or deep socket bigger than 15/16. I think we used a 1 inch wrench.

If it's not the switch, its most likely the oil pump, but don't forget to check the hose, it could be bent or crimped.

Hope this helps :D

High temp low oil pressure light comes on after driving for a few minutes, then off when engine at driving rpm. At stop light (idle or low rpm) light comes back on. Normal driving it goes out.


You need to find out why you have low oil pressure. It is normal that as engine rpm's increase, the oil pressure will rise- the oil pump is moving oil faster. Even though your light goes out, you could still have critically low oil pressure. There should be sufficient pressure at idle to keep the light off. The light will come on when your oil pressure is almost nil- I believe for some it's as low as 8 psi. Normally, oil pressure at idle is specified anywhere from 15 to 40 psi. You would have to check specifications for your Expedition. To verify oil pressure, hook up a mechanical gauge at the oil pressure sending unit on the engine block. Check with a local shop.

The causes run from easy, simple to budget busting ruin. Low oil level, wrong grade oil, real old oil, oil leaks, internal oil leaks, worn oil pump, worn crankshaft bearings. It was pretty common on older very high mileage cars to have a fluttering oil light at stops and idle. It was time for a rebuild, or time to look for another car.

I have a Z24 Cavalier and theres white smoke coming out the exhaust and timing chain makes a lil rattle noise when I first start it in the morning and tends to stall until it reaches the temp of 165ish...


So if it's not consuming oil and you are SURE to fill the radiator to PROVE it's not burning coolant ... then the other suspects are head gasket and .... A puff of smoke upon start-up could be caused by valve guide seals allowing some oil to leak down into the cylinders while the car is parked and not running. This would be pretty common on a nine year old car and should not, in most cases, be cause for concern - See more at: http://community.cartalk.com/discussion/2280708/white-smoke-from-exhaust-upon-cold-start#sthash.05fuptIx.dpuf

If it's blue-white then What you might be seeing is oil burn-off from leaking valve guide seals. The next time you have the oil/filter changed, have a high mileage oil installed. - See more at: http://community.cartalk.com/discussion/2294478/white-smoke-coming-from-the-tail-pipe#sthash.jVo0zDhw.dpuf

Your problem is not the oil pressure sensor, it's because your idling is going too low. If you raise the RPM slightly the light goes out. 650rpm is a little low. I think your car has an Idle control valve ... or look if it has an Idle position sensor. I suspect you have an issue with that.
Hope this helps.

The oil light comes on when the car gets warmed up and is in idle, about 600rpm. Any slight increase in rpms and the light goes out. Oil level is OK. The car has 166,500 miles. Should I worry about this?


YES. You dont say what engine you have? but the 2.7L HAS LOTS OF PROBLEMS. there were some problems with oil sending units for these cars, oil sludging, and timing chain. Have the oil pressure verified with a mechanicl oil pressure gauge, if its low, think about trading it in on another car.

My oil light comes on when car idles below 1000 rpms mazda mpv 2003


Your motor oil level is low.
The oil light indicates low oil pressure - at higher RPMs the oil sending unit (oil pump) can create
a little oil pressure, but at lower RPMs it fails to keep up.
If the oil level is good, then the oil sending unit itself is going bad.

Replace the oil pressure sender. The sender is what is turning the warning light on.If you replace the oil pressure sender it should fix the flickering light problem. If it does not , the light is an indication of more serious motor killing problem. Fortunately, the sender is under $10 and usually fails before the actual oil pump.

if your oil level is adequate, it is more likely your engine's oil pump problem, it is faulty & you have to replace it. before any demage to the engine.

Hello. My oil light stays on at a very low idle


200 rpm's will diffenetly create a very low oil pressure signal. I can not see how your engine will run at 200 rpm's neither. check the voltage output of your altenator for if its bad this will cause a problem such as yours
