So, took the slow mobile out today. After leaving a drive thru, I got a warning of high coolant temps. I look down at my jb4 app and indeed, water temp shows 233°F. Then it drops to 206. So I drive off and it literally jumps from 186, to 206, to 23x then back down to 209 and settles there. Then on my way home, same thing. Jumps to 230s then in 1 second down to 186, then the next second 199.
I am thinking coolant sensor as the wp and thermostat were replaced about 12k miles ago.
Also the fan never kicked on full blast like a wp failure.
No codes, not even shadow.
Thoughts ?
Also on the N54, where is the sensor located ?
