Low Oil pressure light in idle at stop

My 1999 Chevy Malibu's oil pressure sensor comes on when my car is in idle temp and I stop indicating low oil pressure. I've changed the oil pump, sensor(twice) and put in straight 40w oil and the light still comes on. What could be my prob?

Depending on the amount of miles, maintenance records, or how hard the car has been driven either by a previous owner, or by yourself. The engine's main crankshaft bearings or the connecting-rod bearings could be excessively worn.

Also, it could very well be a wiring problem to the sensor and/or computer causing the problem.

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.

Low pressure when at idle, after the engine has warmed up and the oil has thinned, indicates that the oil pump is worn and needs to be replaced.

Check oil light comes on at a stop and while idling


this is a light that indicates low oil pressure or low level, 1st check the oil level in the engine when it is hot, if that is ok you will need to have the oil oil pressure tested with a specail mechanical test gauge, don't wait on this, low engine oil pressure or level can quickly lead to engine failure, have a shop check this ASAP if level is ok and light still comes on.

What is the check gauges light


CHECK GAGES light (1) indicates a potential engine failure(low oil pressure, low coolant, coolant overheating) has occurred.
· Check gages and shut down engine. Gages should read as follows: Oil pressure 5 to 10 psi (34 to 69 kPa) at idle; Water Temp gage below 230 degrees (110 C).
· Check engine oil level (Para 2-11) if OIL PRESS gage indicates low reading. Check coolant level (Para 2-11) if Water Temp gage indicates high reading. Notify Unit Maintenance if levels are low.

If CHECK ENGINE light (2) is on, check engine oil pressure gage (3) and water temperature gage (4). If both indicate normal, proceed with mission and then notify Unit Maintenance. If either one does not indicate normal, stop engine immediately and notify Unit Maintenance

Flickering oil light


This could be two unassociated problems; the flickering oil light can indicate that the pressure sensor for the idiot light is failing- this is not uncommon, the other can be a failed temperature sensor sensor on the main radiator. 
The low oil pressure condition may also be indicative of a worn engine part or parts. It would make sense to have the actual oil pressure checked in a shop to see if it is in the normal range which should lay between ~30 & 60 pounds depending on engine RPMs and engine temperature. The idiot lights trigger at around 4-5 pounds and this is really pretty late for a warning; if the pressure is actually that low, not only lubrication is too little but the cooling effect of the circulating oil is inadequate.
If it was my car, I would replace both sensors before getting too worried. The cost of these together (parts only) should be well under $50 US.

My 1999 pontiac grand am will idle low, but does not cut off.


Sounds like your oil pressure sensor may be faulty. Or your oil level is very low. Your engine should idle as low as 650 rpm without your light coming on.

Low idle


Check your oil level, your level could be to low for the oil pump to pick up properly. The other reason could be in need of an oil change or your oil pressure sensor is gone bad. Your oil pressure come's from your crank shaft bearing and not form you oil pump. Good luck and hope this help
