Hi, My 1995 sl1 was running and idling poorly and over heated and boiled over. The fan never came on. I cleaned the throttle body and replaced the plugs, and also changed the lowertemperature sensor, the two wired one, it was cracked inside.Nowthe car runs great but the fan stays on and thecheck engine light stays on and gives a code 14high temperature sensor voltage. The fan starts when the car is cranked up even if it is cold. I''ve checked the connections . Could this be another bad sensor it is the preferred brass type?

well they are probably going on because of the sensor giving an incorrect temp. Are you sure you wired the sensor correctly and also have the right one.
