More than likely, It might be worth giving the oil system a flush out. If the engine hasn't been properly maintained, sludge can build up in the oilways which can restrict oil flow at low pressure.

replace your oil pressure sensor and have a mechanic do a oil pressure test.

SOURCE: check engine light has come on

You need a code scanner hooked up to it to find out why the light is on.
If there is an advanced auto or an autozone near you, go there and tell them the engine light is on, and you need a code retrieved. They don't charge for this, where other places do. Tales about a minute.

Generally the computer is reading a problem with the fuel pressure being to high or to low. The ICP is one problem it could be and you changed it. The other could be Fuel pressure regulator control solenoid or problems with the injector (s).

SOURCE: Oil light comes on when idling or stopped at

this is due to low oil pressure. i would do an oil change and get an oil filter from the dealer(actually you should be able to get motorcraft filters at any parts store) but dont use fram. up grade your oil to the next heavier weight( 10w 30 go to 10w 40) and see if this make a difference. if no difference is noticed the next diagnostic step is to see your technician and have himperform whats called a wet oil test. by this i mean that the pressure sesnor is only taking pressure and converting it into an electrical signal which if the sensor is bad..... so he takes out the sensor and replaces it with an actual gauge to read pressures. this is the most acurate way to test. from there he will be able to advise you on the next step of repair.

SOURCE: 2001 ford escape.. oil light comes on when at a

this light is indicating your engine has low oil pressure sensed at idle, have the oil pressure checked with a special mechanical oil gauge, if the oil pressure checks ok then just replace the oil pressure sending unit, do this ASAP, if u do really have low pressure u can damage the engine bearings, a very expensive fix.

Why does my oil light come on?


It's possible that when the engine is at idle RPM it may not produce enough pressure causing the oil pressure sender to activate the light. Does it do this when you just sit and idle the motor? You may also have a oil sender that may need to be replaced.

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

My check oil light comes on when I come to a stop and then goes off when I am driving. I checked oil level and it is fine.


Hi. Due to the fact that the oil level is fine, This will indicate that there may be some sludge build up in the block, or the oil pressure switch is damaged. The more serious issue will be a failing oil pump. To isolate the issue, simply, have a oil pressure test ran on this engine. If the test indicates that the true oil pressure is optimal at idle, kindly replace the oil pressure switch. Now, if the test proves that the pressure is indeed lower than factory specifications, this will confirm that the pump is damaged. Have the pump, and oil pump screen replaced, in this case.

NOTE_ I would, also, recommend to have the engine flushed asap.

it sounds like it may only be the oil pressure switch. It should be located near the oil filter. replace it and see. They are not an expensive part. The cruise control has nothing to do with the oil pressure. Hope this helps

Oil light in 1999 Toyota camry comes on when idling.


bad to worn out oil pump or excessive oil passage clearances that allowing more oil to pass thru them at a lower pressure due to the bigger opening. It can be a sign of an emminant engine failure due to oil starvation.
