Hello,
I have a 1994 XJS 4.0 Convertible. The oil pressure gage doesn't work. Car runs great with no issues. I am looking for information on where the oil pressure sensor is located and what the part number is.


Any help is greatly appreciated!

Use that site. Check chassis number and engine numbers then go looking on the net.

The sender for the gauge is the big one. If you pull the wire off and earth it with ignition on the needle should go all the way over. If it does then wiring and gauge are all ok.

Later cars (x300 ) had a gauge that just read in the middle. If you have two small senders then your car had had this mod done. If you have one big and one small then the big one actually shows you the correct oil pressure.

might even be something simple like the wire has come off.

The sender and switch are located on the block forward of the oil filter assembly.

Hope that makes sense.
