I’ve recently had my MIL / CEL come on like many others. Checking on some of the instruments and gauges I found something that was rather alarming. Vehicle has been sitting overnight so all fluids should be ambient temperature (93f outside temp) The oil temp gauge in my instrument cluster showed 82f. Went into the off-road pages and it shows 419f for oil temp!!
Have others experienced this?

If that doesn't reset with a key cycle then I would suspect a fault with the sensor or wiring.

I haven’t taken it out long enough or fast enough to have the engine kick in yet. But checked the vehicle several hours later and it still shows the same temperature reading for oil. Wondering if it may be related to the CEL light I have? Going to try and get it to a dealership soon for a diagnostic.

I would force the engine to start and then see if the CEL goes away. If the engine hasn't started yet then it might just be a programming thing with the engine calibrations.

Had a chance to do a quick run the in the Jeep- as it turns out once the engine kicks in the oil temp drops and matches the gauge cluster oil temperature. Running in normal ranges.
So just another strange quirk with the Jeep / Uconnect.
Appreciate the insights from those above.

I might be late to this one, however the 419 is an Easter Egg..... It is the area code for the Jeep Factory in Ohio. Only comes on for a couple minutes when you start up.
Easter egg, lol.

I've put plenty of easter eggs in my software over the years. One I do is make all my error codes a 1202. But I don't think anyone has ever gotten it yet.
