Faulty "Check engine"

Had a little scare this morning. The wife had to move the Liberty so I could get my Honda out of the driveway to go to work. At first I thought she was dimming to parking lights not to blind me, only then did I realize she was flashing the lights at me. Not exactly being awake at 5:30 a.m., I wandered back to her and asked, "What's up?" She promptly pointed to the dash and the check engine idiot light. "Great", I'm thinking.

So all day at work I pondered what was going on with the Jeep. Could it have been my Ernesto water fording that had caused a problem?

Got home disconnected the negative on the battery for about five minutes to flash the computer and then hooked it back up. To my relief the light was gone. I figure some sensor must have been wet sending a faulty code.

Now I've got to go out and reinstall my front swaybar and new JKS quick disconnects. Getting it aligned again on Thursday. Still got to mount my HiLift jack and install some 1/2" spacers in the rear.

Getting stoked for Crozet, Virginia this weekend. Wish me luck!

I get that check engine light everytime I power wash the engine itself - It's gone in a day...
Weird

Why didnt you pull the codes?

I washed my engine one time and it said I had a bad water temp sensor. I unplugged it and checked everything, then plunged it back in and unhooked the battery. Everything was good to go.

I didn't pull the codes due to not having an OBD, that and working in Virginia and living in North Carolina, everything is closed when I get home.

Isn't there a way to pull the code up where the odometer is? I thought i read on here somewhere about doing a trick with turning the key on and off like three times or something? You better take some pics of this coming weekend Mutt and share with us!!!!
