Have the oil pressure check mechanically to remove the pump as a source of the problem
check the oil level in the sump to remove that as a source of the problem
replace the oil pressure sender or sensor unit

SOURCE: where is the oil sending unit on a 2000 5.4 litre expedition

the pressure sender is near/next to the oil filter. And yes this does sound like a sender issue.

SOURCE: Oil pressure suddenly dropped to zero.

Hello, let's see what you need.
Yes, the pump can go out that fast.
Do not start your engine. Go out and check the oil. If you have plenty of oil you will need to tow it to a shop. If your out of oil check the the drain plug on the oil pan and check the oil filter.

see if you have any oil level or pressure sensors. sometimes these can get gunked up. You may need a new oil pump. I suggest you start using a senthetic oil (valvoline,mobil 1 is reccomended) after u get the problem fixed.

Oil light comes on at stops after engine is warm


if your saying that your low oil pressure light is coming on (or flickering) at engine idle , but goes out when engine is above idle (going along) this is sure sign you have a problem in your engines oil pressure system :
serious !~


some common reasons for this to occur are:

worn out engine parts allowing oil to leak out and not lube parts properly (hi engine miles)

low oil level -not enough oil inside engine to get pumped around proper


restriction in oil system - blockage in oil passageways even oil filter will count (hi miles)

3.5L V6. Why does oil pressure light turn on intermittently?


1. As a basic measure I would make sure the correct grade and spec oil is going in the engine. You can no longer trust that a local mechanic or even a dealer service center will necessarily use the required product as stipulated by the manufacturer. It is always better to buy and supply your own so you know the correct product is being used.

2. I would not assume there is a problem with the oil pressure warning light even though there could be.
The first thing the mechanic should have done when you reported the oil pressure issue is to hook up an independent mechanical oil pressure gauge and check oil pressure when the engine is hot at different RPMs. Any oil pressure issue will usually show up at idle when the engine has been warmed up properly and the engine oil is hot (unless you have some kind of intermittent oil pressure relief valve that is sticking). Just replacing parts without actually knowing what the oil pressures are at different RPMs is being sloppy and negligent.
This is what you need to do now. Contact a business that can hook up their own pressure gauge to your engine and have them check the oil pressure readings at various RPMs when the engine is fully warm. If there is a low oil pressure issue it will show up on the oil pressure gauge. As you have a new oil pump there should be no issue now with oil volume or a sticking oil pressure relief valve which on your engine should be part of the oil pump assembly.

3. Worn engines will not be able to sustain required oil pressures. Oil pressure is not produced by the oil pump. The oil pump produces oil flow but the resistance to flow is what produces the oil pressure and that resistance is created by fine clearances between operating engine parts especially on the crankshaft and components connected to it. Once the engine wears the clearances increase and the oil flows past the parts much more easily and produces/builds much less pressure.
How well your engine with over 90000 miles has been maintained depends on how often all the owners changed the engine oil and filter , whether they kept the engine oil level up to full (most owners rarely ever check oil levels between services) and whether they always used the correct product. Manufacturer oil change intervals shown in service schedules can be 10000, 12000 miles or more which is much too infrequent for the type of use 95% of private vehicles experience which typically are on the severe to very severe use end of the spectrum. Engine oil typically needs to be changed at least at half the mileage shown in service books (at least twice as frequently) and thus at least every 5000 miles if you want your engine to last.

Oil pressure gauge flickers all over then goes to zero shut engine light comes on oil has 1000 miles on it 5w30 control cold or warm may return to normal 60/70 then 0


Problem could be a bad oil pressure sensor or the oil pump is failing. A mechanical oil pressure gauge needs to be hooked up to verify actual oil pressure. Problem could also be a bad stepper motor in the instrument cluster that drives the gauge.

2006 Chrysler 300M 5.7 Hemi, all of a sudden the oil pressure has dropped to "0" when in idle or at a stop sign, and the light comes on, then when accelerated the light goes out and pressure resumes, and...


The check engine light means there is a trouble code stored in the car's computer. The first thing is to get this read out, to home in on the problem. Autozone will do this for free I believe.

It is not uncommon for the oil light to flicker at idle when hot, as long as the pressure rises OK at revs. Get an oil pressure reading done by temporarily replacing the pressure sender unit with a pressure gauge, and you can then tell if there is a problem in that area.

It's OK that oil light flickers or comes on while starting. It turns off when oil pressure comes up to normal. That won't happen till car is running.

2003 Hyndai Elantra oil light has started flickering, Why?


If it flickers at idle, it "might" be engine wear, especially if you are approaching 200,000 miles. It might also be a faulty oil pressure gauge sending unit which is a little more likely.

My oil pressure light comes on at very low speed on 96 camry


Take a gauge and check you oil pressure. If its not low then change the pressure sensor. If the pressure varies and the pressure is not where it is supposed to be, then drop the oil pan and look in the bottom of the pan. If you see slivers of metal then the bearings are going out. Eather the cam bearing, rod bearing, or main bearings.
