Coolant Temperature Sensor Fan Always On at Abbey Battye blog

Coolant Temperature Sensor Fan Always On. Your check engine light is on: The engine coolant temperature (ect) sensor measures the coolant temperature in the cooling system. The engine coolant temperature sensor is especially vulnerable. A radiator fan that’s always on likely has a serious issue preventing it from stopping, which is best diagnosed by a mechanic. You can usually find the ect sensor near the thermostat in the cylinder head or thermostat housing, while a second sensor sits on a different part of the engine or radiator. But when just one sensor fails, an array of concerning symptoms can emerge. Its failure can lead to severe issues. A radiator fan running when the engine is cold means there are one or more wiring issues somewhere in the vehicle. If a radiator fan continually runs long after the engine is off, it’s commonly due to a faulty cooling fan relay or electronic control unit, or the radiator needs cleaning. If the cooling fan constantly runs, it indicates one of these reasons: Failure of the coolant temperature sensor or its wiring, fan start relay failure, damage to the drive motor wires, failure of the. However, other issues like a stuck open thermostat, malfunctioning ecm/ecu, lousy fan relay, and faulty coolant temperature sensor can be the leading cause. If the engine’s computer detects a problem with the coolant temperature sensor, or its circuit, it will turn on the check engine light. The coolant temperature sensor is a thermistor and its resistance changes when the coolant temperature changes.
