Temperature Sending Unit is on the driver's side of the car. Upper cylinder. There are two heat shields covering the fuel injection system. On the driver's side just behind the Upper Radiator Hose is the bleeding valve to bleed air from cooling flow. Behind this valve under the heat shield is the temperature sending unit. My 1993 was doing the same thing. After replacing everything due to consistent overheating (radiator, water pump, both upper and lower hoses, and head gasket) dash still read hot even after letting car sit for days. Then thought perhaps a sensor somewhere cause if stays HOT according to dash gauge, PCM will eventually throw an error and cause check engine light to come on and thus shut down and won't allow restart for some time to prevent further damage to engine. I am glad to know I am not the only one having this issue since my wallet is in torturing pain after spending $2600 to fix it. However, despite the repairs, she is driving nice and I'm riding it like it's stolen again! Hope this helps -- Best of luck!

How bad is it to drive with a bad oil sending unit that is reading 80psi all the time?
If that is all that is wrong and you know 100% that the sending unit is bad, then my advice is to replace it. It is a cheap fix and if you do not replace it you have no idea what your actual oil pressure is. This could cause you to drive around with no oil pressure which would destroy your engine. Just replace it and then you can rest easy.

What does it mean when your oil pressure gauge reads?
It does NOT automatically mean you have 80# of pressure! NEVER trust your gauges as being the 'last word'. They're notoriously cranky on some older XJ's. (Usually due to gauge cluster connection issues or harness oxidation.) Chances are that you have a defective oil pressure sending unit. Rarely the gauge goes bad. Remove the wire on the sending unit and see if that changes the reading. If it does, replace the sending unit. If not, I'd still replace the sending unit. After you confirm the oil pressure sending unit is good, check the oil pressure relief valve. It may be stuck closed resulting in high pressure reading.
