1999 Deville base
95 Eldorado, 99 Deville, 05 CTS
I finally got the windshield replaced and the car tagged, after sitting almost a year, but it has a p0118 coolant temperature sensor circuit high voltage. Engine light on constantly. Wont stay cleared. Temp on dash saz 194 after warmups and never varies. Scan tool Freezeframe saz 40° cold, and 35° after warmup. If I jump the sensor connector, I get 304°. (All F°) Its a new sensor. ?? Any ideas, anyone? Like, maybe, someone that's had this very same problem, and will tell me how easy it is to fix! Thanks all!
