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.

My 2000 expedition oil pressure needle drops while driving


If the engine is heating up then you need to check the condition of the engine , check the oil , if there is level drop in the sump or if the oil is old and gone too soggy. If so replace with new filter.
However is the engine seems trim and working fine then the oil pressure guage needs a check. Test with an alternative before confirmation or else the oil pump is a suspect at higher temperatures.

I got in my 2001 Expedition, started it up and the oil pressure light came on. The guage was down to 0. I stopped it and started it again. The guage press. went up and then slowly dropped at first and...


oil pump gears inside the lower engine, or electrical. 1st make sure its full on oil, then sheck it with another pressure guage to confirm its not actuall pressure.

The oil pump may be going out - the light indicates the pressure is below the proper level and when you step on the gas it spins faster/raises the pressure back up to an acceptable level.

This is something to get checked RIGHT AWAY, as these cars have a history of engine failure....possibly due to low oil pressure.

Check this LINK for more info.

The emissions system may be related, but get the oil pressure issue fixed 1st.

Low Engine Oil Pressure

The oil light is signaling low oil pressure in the engine's lubrication system. You say that you have checked the oil level in the engine and it is ok.

The oil pressure needs to be checked with an oil pressure gauge. (It is most unlikely that the warning light is faulty).

Should the oil pressure prove to be low - as I expect it will - the cause needs to be investigated. It is likely that there is a malfunctioning or failed oil pump or the oil pressure relief valve is sticking in the fully open position.

Failure to change the engine oil, at least at intervals stated by the manufacturer, will result in severe oil degradation and reduced oil pressure. However this is usually not enough to trigger an oil pressure warning light.
If you have changed the engine oil in the last six months or so, and have not done over about 7000 miles since then, oil degradation should not be contributing to the low pressure problem.

If the oil pressure gauge check confirms low oil pressure I suspect, on further investigation, that you will find a problem with the engine's oil pump.

You will need to get your vehicle to a reputable auto service shop to have the oil pressure checked and the problem investigated. Do not drive the car in this condition (except to get it to the repairer). The engine is not receiving sufficient lubrication and you run the risk of expensive engine damage and total engine failure.

Hope all goes well with it. Cheers.

2001 a4, oil pressure light alarm.


Your mechanic is yanking your chain. (or you mis-understanding.)

Oil pressure light does not have to be "reset." There may be CODES that need to be reset but they would turn on the CHECK ENGINE LIGHT. (I think, on your car, this is picture of engine with a check mark.) If the Check Engine Light (CEL) is flashing, it means you have a serious engine problem and should NOT be driving the car without finding the reason for the light. (Around here, many auto parts store will "pull the codes" for free.)

Oil pressure light could mean you are low on oil, have a bad sensor, wire or even a oil pump. The oil pump is inside the engine.

when you travel over 65 mhr for long lenghts of time you don,t work the engine enough to move the fluid to lubricate the engine also when you go on long trips make sure the oil life is still gonna be good for the hole trip
