Toyota Owners Club Posted April 23, 2018 Share Posted April 23, 2018 Sounds like the Coolant Temperature Sensor/ThermoSwitch is faulty or the wiring leading to one of the fans. I would bridge the connectors on the plug going into the sensor and if the fans run with the ignition on then it has to be the sensor at fault Quote Link to comment Share on other sites More sharing options...
