You need to install an external oil pressure gauge and determine the true oil pressure. The problem could be just an oil sending unit.
When the oil light comes on when a 2002 Ford Taurus is idling it means there may be a problem with the oil pressure that needs to be checked.
The 2.2L and 2.4L uses a chain.a bad chain or tensioner will make the oil light come on at idle
Check the engine oil, sometimes when the oil is low the check engine light comes on while sitting still and goes out when you accelarate.
oil light comes on when there is not poper amount of oil in engine. if proper amount is in engine and light comes on at idle, maybe the oil needs changing. oil looses some of its viscosity when old/you might also check oil sender unit and oil pressure gauge. it all these are good you need new oil pump,as it is loosing pressure at idle. just because oil light comes on , DOES NOT mean you need new main bearings. YOU WILL KNOW WHEN U NEED MAINS AS THE ENGINE WILL RATTLE LIKE A THOUSAND LITTLE MEN IN IN WITH HAMMERS. THIS NOISE WILL ALSO GET WORSE WHEN YOU REV ENGINE
The most common reason for the oil pressure light to come on when your vehicle is idling, is low oil. Check your engine oil and make sure the oil is up to the full mark on the dipstick.
Are you saying there is enough oil in motor? If so could be low oil pressure and or bad sender, how many miles? how hot was it when oil light came on? If it does it only HOT and at idle that is kinda of normal as it means low oil pressure at idle, Porsche talks about that in their owners manual say back in the 80;s SC's and 911's
put some oil in it ?
I remember once i overfilled my oil tank and my fuel injection light comes on. its blinks when you are on idle. It wasnt permamnent. as soon as the oil level dropped the light went away.
If the oil light only comes on when the engine is hot and on idle look at your oil pressure gauge to see if the needle is going down to the low end of the scale if so give it a service and make sure you use 10w 40oil reccomended for frontera and you can put in slick50 or other engine oil additive this will increase your oil pressure and stop the light coming on
Defective oil pressure sending unit? Excessive engine wear (bearings)? weak oil pump? Try installing a manual gauge to determine actual oil pressure
Your oil light comes on when the OIL PRESSURE is too low ( your engine oil LEVEL may be O.K. )
* low engine oil level * plugged oil filter * oil pump is failing * oil pressure sending unit is failing The first 2 are eliminated with a fresh oil change.
