I picked up my new JL sport a few months ago and been loving it. Im at 2k miles now. However this morning I noticed the fans running loud on acceleration . 15 minutes later check engine light appeared. The code is p0118 ECT Sens voltage too high. There is no reading of the coolant temp on the dash. I also noticed a clicking noise coming from the fuse box. Not sure what caused this. The day before it was driving fine. Does anyone have any experience with this ? I would rather try to a fix it than waste time at the dealer.

The jeep is lifted on 2 1/2" lift on 37" tires not sure if this can cause any issues

You may have a defective coolant sensor or a loose connection in the ECT circuit. Make sure your fuses and relays in the EDC are all fully seated.

Thanks for the input. I double checked the fuses and relays. I made an appointment for service but i hope they dont give me a hard time because of my after market headlights and DRLs.
