Coolant Temperature Spike. What gives?
So I'm living this nightmare. 2015 Renegade Trailhawk, 55k miles. Coolant temp suddenly went in the red at 250
F in stop and go traffic on a 90 degree day. CEL came on. Checked the code and it was p0117, low voltage to the Engine Coolant Temperature Sensor. Open the hood and I noticed the radiator fan was not running. It only kicked in when I tapped it, and after that it doesn't stay on more than 10 seconds. Let it cool off and drove home. CEL is now gone, but the problem still happening. No leaks, coolant full, before I go to the stealership and get raped, I want to see if anyone else has this issue and how they handled it.
I'm pretty good fixing issues on my Jeep in the 3 years I've had it. Second major problem, first being the transmission locked due to the computer needing a reset. That was done last summer.
Talk to me, fellow Rene owners.
