You have a check light on

They have been on all vehicles for over 30
years,so there shouldn't be any reason not
to have checked for codes,to find out what system
has a fault

The oil press thing could be any number of things,
from a bad sending unit to other electrical issues

SOURCE: oil pressure high when engine cold. but fine when engine is warm

It is normal for oil pressure to be higher when the oil is cold. As the oil heats up, it will thin out. Since your oil pump is driven faster with the acceleration of the engine, your pressure will also increase. On a engine up to full temp, your oil pressure will probably be around 20 psi and maybe up to 60 at full load. But on a cold engine, you may see 60 psi at idle. I dont know if your high oil pressure is causing your vehicle to stall, but maybe your running the wrong weight/type of oil for your truck. If you live in a extreme cold area, you may want to look into a block heater to help warm up your engine faster.

Oil light is on car is full of oil engine is making taping noise is the oil pump gone bad on a 2000 crysler concord with a 3.2 engine


The oil light comes on when oil pressure falls below 7 pounds of pressure. A tapping noise from the engine is an indication of poor oil flow/pressure supply. You may have an oil pump failure or if high mileage, excessive bearing clearances that can cause oil pressure problems.

Is there a oil safety switch on 2002 Chevy s10 zr2


You have a oil pressure switch which is located by the oil filter,it is screwed into block,just removed electrical connector,get wrench and remove.
  • When the oil pressure is either high or low it will either turn the oil light "on" in the dash or move the gauge to the extremes
  • Undetected high or low oil pressure can result in internal engine damage and/or gasket leakage. Here's a picture of what it look's like.

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.

Location of oil sending unit on 1990 ranger 2.9


Here's a link to your oil pressure switch,here's the part.As you can see there are 2 types,one for light and one for gauge.
  • When the oil pressure is either high or low it will either turn the oil light "on" in the dash or move the gauge to the extremes
  • Undetected high or low oil pressure can result in internal engine damage and/or gasket leakage

Oil gauge drops low at idle


Low oil pressure at idle can be caused by an engine with worn rod or main bearings due to (usually) high mileage . This however does not mean the engine is still not serviceable as long as the oil pressure is low only at idle. The pressure should at minimum get into the normal range at anything above idle speed.Not much oil pressure is really necessary at LOW speed. At low speed, as long as there is oil getting to the bearings, even at low pressure, you are OK. In a high mileage engine the oil pressure is often low at idle simply because the oil pump is turning slowly and cannot maintain higher pressure between the larger than normal crankshaft and bearing clearances. As speed increases the pump turns faster and supplies more oil and the pressure should go higher. Low pressure as long as it is only at idle is not a problem. However at higher speeds the pressure should be in the normal range. Such a worn engine can benefit from higher viscosity (thicker) oil such as 20W-50 in above freezing weather and 10W-40 in winter. That will increase idle pressure and the thicker oil film maintains a better film between the worn parts

2004 lincoln avaitor oil light comes on the engine shuts down


Does the oil light come on BEFORE the engine shuts down? I have to ask because it is NORMAL for the oil light to be on when the engine is not running. I had a customer that said the same thing just last week. After we wasted a bunch of time (which the customer ended-up paying for) checking the oil level, the oil pressure, and verifying correct oil pressure gauge, light, and sending unit operation, it turned out that the crankshaft position sensor was bad and causing the engine to shut down and it had absolutely NOTHING to do with the oil light - it was functioning as designed.

If the oil light is coming on before the engine shuts down, the first thing you need to do is check your oil level. If the oil level is OK, you need to check the oil pressure with a gauge to determine if there is an actual engine oil pressure problem or if the oil pressure sending unit, gauge or light is malfunctioning. Also, it is highly advisable to not drive the vehicle AT ALL if the oil pressure light is coming on while driving until the cause of the light coming on has been determined and repairs have been made. Otherwise, SEVERE ENGINE DAMAGE may result.

Why does the oil engine light come on when i engage the clutch ?


Hi!

When a car is in gear with the Gas pedal pushed down, the engine RPM is high so the oil pressure is high too that means the Sending unit is detecting high pressure. But when you engage the clutch that means the gas pedal is released so the RPM drops and the pressure drops down too. So all i can say is that you might have a bad oil pump that needs always high RPM to keep the oil pressure normal.

Good luck

While stop oil light blinks on not whlie i am driving.


When the engine is running at idol the oil pressure drops causing the oil light to flash or come on. While driving the engine is running harder and oil pressure is increased and the light goes off. Your oil level may be low in the engine or the oil pump is starting to fail. Is this a vehicle with high mileage?

High oil pressure.... and the check engine light came on


These two are 99% not connected. how high is your oil pressure? this is probably the normal oil pressure and you just started looking at thing since your check engine light came on. you could also have a problem with the oil sending unit itself.
go to garage and have your engine scanned.
if you have any more problems with your jeep you would be better off to post on a jeep forum like
http://www.jeepforum.com/ you will get alot of helpful input

Engine light on/Oil Gauge on stays on high


Any waranties left? Is oil full? Any noises from engine? Did you put a mechanical gauge on it and check "real" oil pressure? (I would not drive it 'till I was sure about actual oil pressure!!)
