When I am driving my car the (STOP oil pressure is too low) light comes on. I have taken it to a garage and had the oild pressure switch replaced and this is not the problem. When the car is idol and i am not using the accelorator the light comes on and when I am driving it goes back off. What could be the problem? Is it dangerous to drive? how much will it cost to get fixed? I drive a Peugeot 207 which was registered on the 01.04.2007 and has only done 24000 miles.

This is not good, the reason the light is on is because there is not enough oil pressure at idle, your garage was right to try the oil sending unit that is what i would have done also but now you need to have them remove the sending unit and install a manual gage to see just what the oil pressure is at idle if the pressure is more then 20 psi at idle then their is some thing wrong with the instrument cluster of wiring to the oil gage if the oil pressure is less then 20 psi at idle with engine at operating temp. then you will need an oil pump or maybe even a bearing in the engine has failed that would be hard to believe at only 24xxx miles but it is a Peugeot.

when we get to Heaven there will be no cars, but for those that go the other way that place will be full of them and the Devil himself drives a Peugeot!

    I too have been having this problem and had taken the initial step of replacing the the oil pump switch too at a cost of £40. It ran fine for a week before my little red light friend returned.I have since had the sump removed and found white metal in the sump oil and oil filter. I have been informed this means a bearing is shearing in my engine and is a degenerative problem with no hope of rectification other than an new engine. Is this advice correct as it cost me £96 to find this out and after already spending £40 to get the oil pump switch changed I am reluctant to invest any more money into this problem, please let me know of your experiences in this. My garage has told me this is indicative of soft metals being used to build poor quality engines.

Looking for oil pressure sending unit in 2000 Ford Contour SE.

Oil pressure sensor or switch has to be connected to the main oil gallery and it is generally most convenient screwed into the oil filter head or the gallery side of the cylinder block - you omitted to say whether your car has an oil pressure gauge?
If there is a gauge the light might be switched by the gauge itself or if the gauge is electronic and computer driven, the computer might be switching on the light.

It is worth checking the vehicle handbook or a wiring diagram to be certain what you have and how it works.
Some vehicles are no longer fitted with an oil pressure light and other vehicles have a light for the oil pressure and another for temperature and/or oil filter blockage.

Low oil pressure light on shouldn't be taken lightly and if a replacement switch/sender doesn't cure it, you should have an oil pressure test carried out asap.

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.

This may mean engine wear or bad oil pump. I would have the oil pressure tested to see if its a shot some where or if the pressure is really low, this is done by removing the sensor and installing a gauge and driving the car to see if the pressure is low, if the pressure is low then more checking is neede to see why,you may have worn engine bearings or bad oil pump. depending on the mileage it may be smarter to replace the engine, not knowing what internal damage has been done already. good day.

Where do i find the oil pressure switch on the toyota tarago is there one or to I replaced the one on the side of the motor near the starter motor but the red oil light is still coming on

First, do not keep driving if the oil warning light is on or your oil pressure gauge has dropped. Stop the engine, let it sit for a few minutes, then check the oil level.
If the dipstick shows a full oil level, then low oil obviously isn't your problem. The oil pressure may be low because of a worn or broken oil pump, a plugged oil pickup screen in the engine's crankcase, possibly a plugged oil filter or excessive bearing wear. Or, the oil pressure may be fine but the oil pressure sending unit has failed. Further diagnosis will be required to determine what's wrong.
Perform electrical tests on oil pressure switch http://www.clarks-garage.com/shop-manual/elect-19.htm
Replace pressure switch as the cheapest means of repair to see if the lights go out .
The pressure switch will be located on the engine block.

On my 93 Dodge Caravan ES 3.3L, when it comes to a stop and idles (at a light mostly) the check gauges light comes on. When the check gauges light comes on the oil gauge is at the bottom. When I tap...

Okay What it means is that the oil in your car is either low in level or the oil pressure at low revolutions is low. I highly recommend you to stop driving the car when this happen because you can internally damage the engine with a low oil or a low pressure of oil. Check the oil level first..make sure level is fine and oil looks good. Black and burned oil will give you a low oil pressure as well. If it happen that your car need a oil change. Make sure you get it done and see if the problem goes away. Very rarely oils pressure sensor goes bad but if oil is new and level is fine you can take the oil pressure sensor and connect a tester for a oil pressure. If this is not under the manufacturer specifications.. oil pump is worn out and you have to replace it for a new one.
Good luck and don't forget to rte me. Thanks

Oil light stays on although level is up.

Either low oil pressure, or a leaking switch. If your switch is not leaking, you most likely have an oil pump problem, or a worn out motor.
