Speedometer not working low oil pressure light on and EPS light on

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.

fixya, hybrid fixes.. wow......
double posted too,,,, back up one.

wendy dont fiddle about in any hybrid, there is High voltage there
lethal as H3LL. nor with Air bags, Read the FSM. first.
and post engine RPM at low oil pressure, and dont drive it.

The warning light means the engine oil pressure is low, not necessarily that the oil level is low.
The problem could be the pressure switch, or you really could have low oil pressure.
Driving the car with low oil pressure will damage the engine.

Hi there lose of power steering and the eps light coming on could be the power steering pump is broken or near stuffed so will require a new pump. The other reason is that your power steering oil level is to low and needs toping up. Also check that the drive belts driving the power steering pump are tight and not slipping.

Hope this helps.

Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

The oil pressure gauge on my 2003 Avalanche reads "0" and activates low oil pressure warning. Oil level is OK and engine does not sound like one with with no oil pressure; AKA no knocks or ticking. The mileage is 50,000 on this vehicle any ideas as I with no gauge I am leary of driving it? Please advise!

The oil light comes on when there is low pressure not because there is low oil. If the engine wasn't making any ticking or clunking noises when the light cam on I would bet that an oil pressure switch will take care of the problem. If the engine had make a lot of noise and/or the light never wnet ou I would then suspect that there is a problem with the lubrication system.

If you post an engine size I'll let you know where the switch is. Typically they are near the oil filter and have a green connector.

possible short in ignition switch or cluster panel

is itr the oil light ??check oil level anyway ,iam colour blind so i have a job with the yellow green and red bulbs so i always look at the symbols green is normally generator,yellow indicators and red oil light pressure ,well it was when i was young

You either have a loose/worn engine bearing or a worn out oil pump, do not drive the car this way, you will cause serious damage to the whole engine. A oil switch is for a light, it turns on the light when oil pressure falls below about 10 PSI, a sending unit is for a guage that shows oil pressure with a scale, it may have numbers on the guage or just green and red, or high and low.
