Hidden down the back above the trans bellhousing. The sensor feeds data to the pcm. The PCM switches the fan relay. The sensor also supplies the data for the temp gauge and pcm temp compensated parameters. Unless your seeing multiple faults unlikely it's the sensor. Faulty power /earth's to the fans or suspect fans or relay are more likely. Has the car been tuned? Link to comment Share on other sites More sharing options...
