think its underneath by the fuel tank ,but you shouldnt need to change it i have a 94 XJ6 4lt and i have never had to touch anything ,just changed the oil and filter ,evan the plugs havent needed changing in 2 yrs ,but you must polish it every week and clean the leather once a month with that stuff that keeps it supple .and dont forget to polish the chrome exhaust cover on the exhaust manifold

oil sending sensor could be bad. I know a few different type of cars have trouble with the oil sending unit. They all pretty much do the same thing, "oil light comes on at idle and goes off as you drive". But on the other hand it could be a little more serious.

Too fast an idle speed. If an engine without
computerized idle speed control is idling too fast and refuses to
come down to a normal idle speed despite your best efforts to back off the
carburetor idle speed screw or air bypass adjustment screw (fuel injection),
air is getting past the throttle somewhere. Common leak paths include the
carburetor and throttle body gaskets, carburetor insulator spacers, intake
manifold gaskets, and of course, any of the engine's vacuum fittings, hoses and
accessories. It is even possible that leaky O-rings around the fuel injectors
are allowing air to leak past the seals. Another overlooked item can be a worn
throttle shaft and a defective idle speed speed control motor/valve stuck in
the extended (high idle speed) position/throttle position sensor. Also the
throttle plate could be binding in its bore and kinked accelerator cable,
coolant temperature sensor might not be operating properly misleading the computer
that the engine is still cold and computer throwing fuel at it raising the idle
Getting this possibilities checked will help.Thanks.Helpmech.
