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.

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.

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.

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

electric senders read the full range, you might have a faulty sender or it could be a new design on the pump and oil galleys that provides a consistent oil pressure. or the gauge itself could be stuck..

Low oil pressuer light comes on when at idol

You'll have to determine the actual oil pressure. We use a mechanical gauge fastened to one end of a 3' length of high pressure hose. An appropriate fitting at the other end of the hose is threaded into the opening that the oil pressure sender is removed from. Run the engine until warm and read the gauge with the engine idling. If the oil pressure is below 7 lbs the engine probably has seriuos problems. If the oil pressure is higher than that you probably have a bad oil pressure sender. Otherwise you can just change the sender and see if that corrects your problem.

Oil pressure sender ohms - resistance for 2003 tdi jetta

Most guys do not actually test the sender, as it is somewhat hard to do, as you must know the pressure to evaluate what reading you get.

IF you suspect you have incorrect oil pressure, test the pressure by using an external pressure gauge. If pressure is okay, just change the sender.

If the pressure is NOT okay, shed tears and commence surgery to find cause.

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.

Replace your oil pressure sender and see if the dash warning lights turn off. If after changing the oil pressure sender you still have oil pressure warning lights on, you may have to replace your oil pump in your oil pan.

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.
