It's just came on today after the jeep spent the night in mud and got it pulled out this morning. Only buried to the axles was not wet mud more like muck. But it drove fine then started hesitating a bit then the code came up

From what I've read (Google, of course) it's an O2 sensor code. Probably from sittin' in the mud all night. A good cleaning of the underside (maybe even a pressure washer?) might clear the code. My search mentioned something about the MAP sensor, too. But, basically, when you sink them in the mud (especially if you leave them sit), some major clean-up is in order (don't ask me how I know :shock. Good luck!
