What Sensor Turns On Cooling Fans at Mike Fahey blog

What Sensor Turns On Cooling Fans. Here are some common reasons for this issue: When the air conditioning compressor is turned on, it is normal for the radiator fan to turn on due to the activation. A signal from the coolant temperature sensor is what triggers the ecu to turn on the radiator fan, and if it’s faulty, it can prevent the fan from working at all. If the fans aren't supposed to come on when the cts is unplugged, maybe just the sensor that tells the fans to come on when ac is turned on is bad.whatever sensor that is. What sensor controls the radiator fan? In some cases, the radiator fan will require the radiator fan when the temperature sensor in the bottom tank of cooling fluid exceeds roughly 212f. Check the coolant temperature sensor. On other car models, the cooling fan control module controls the radiator fan. However, other issues like a stuck open thermostat, malfunctioning ecm/ecu, lousy fan relay, and faulty coolant temperature sensor can be the leading cause. The most common cause of a radiator fan. A radiator fan running when the engine is cold means there are one or more wiring issues somewhere in the vehicle. In most cars, the powertrain control module controls the radiator fan, which collects data from the engine temperature sensor.
