Which motor do you have? the V8 requires, according to the shop manual, that you remove the intake manifold. This is a big job suddenly. have you put a code scanner on the car and determined that the sensor is bad? If you are unfamiliar with what to do and how to go about it i suggest going to a local garage and asking them to advise you. They will at a minimum give you a quote with the parts and labor and that will definitely clue you in. You may also Google the job with the specific engine (etc.) and see what you find. Again, you must include the details or you will not learn anything of real use.

3800. Where is the oil pressure sending unit located?

I'm not familiar with your vehicle. However, an oil pressure sender unit is usually located on the block, below the cylinder head.

it's more often than not a screw - in unit which may have a brass appearance and have 1 or more electrical wires coming from it.

Here is a link which will show you generic images of sender units:

They are -usually - just screw-in items. They are not difficult to change.

1997buick park ave won't stop d inging when driving oil light flashes...check oil and it has oil...driving me crazy

Hello Robert, you could have a bad oil sender unit. Install an auxiliary oil pressure gauge to measure the amount of oil pressure. If reading is around 15 PSI or better at idle, change the oil sender unit.

Oil light trailblazer

Check oil pressure with a gauge. The sender is electronic and could be the issue. Also oil filter could have a bad check valve. Change the oil filter, oil and sender. If the problem is still there you have worn engine bearings and major issues are coming your way.

We had the oil pressure sender replaced on our 2002 Neon, what do they have to take apart to change this

no, the oil pressure sender merely screws into a port over an oil passage. to replace you just undo the connection, unscrew the old one, screw in new one, and re connect

Oil light comes on

Change your oil pressure sender. The oil pressure sender will usually break before the oil pump will. If you are driving with the oil light on and the motor has not seized the oil pump is probably all right.When your oil light comes on you need to turn your car off immediately so you do not damage your engine crankshaft and camshaft bearings. If you change the oil pressure sender and the oil light stays on then you should replace your oil pump before more serious damage happens to the motor.

The oil light comes on when the van is in idle, but not all the time mostly after driving awhile. All the fluid levels are ok. The oil & filter was just changed a couple months ago.

Replace the oil pressure sender and the problem should be solved . Fortunately , the senders tend to go out more frequently than the oil pump. If you change oil pressure sender and the light keeps coming on , you may have to consider replacing the oil pump in the motor or risk getting stranded some where with a blown motor.

Have an 04 lancer. Oil light comes on sometimes just flickers, but only after warmed up and at an idle. driving down the road the light stays off. Oil never low and just changed with filters, brand new...

Replace the oil pressure sender. The sender is what is turning the warning light on.If you replace the oil pressure sender it should fix the flickering light problem. If it does not , the light is an indication of more serious motor killing problem. Fortunately, the sender is under $10 and usually fails before the actual oil pump.

Change oil pressure sender

If you have a gauge, the sender usually can be removed with a regular wrench. Some with a light (depending on design of the housing) need an oil pressure socket made just for that (last count there were three sizes).Generally you don't need any thread sealer on either, but I usually make one turn of teflon tape on threads just to be safe.
