Any Jeep technicians out there?

You disconnected the sensor with the car off I take it? At least 5 minutes but try a half hour. Do not disconnect the negative or positive at that time. You can and probably should clean any corrosion on the terminals. Give the battery a charge. It's probably an AGM which some lesser chargers won't actually work on. I've reset a not ready for Autoshutoff light on a few KL jeeps by disconnecting the sensor. If it didn't work you probably need either the sensor or the battery or both!
