Is it possible that a faulty temperature sensor would cause a car to overheat?

Yes, a faulty temperature sensor can contribute to a car overheating. If the sensor inaccurately reads the engine temperature, it may fail to trigger the cooling system, leading to inadequate cooling. Additionally, if the sensor sends false readings to the engine control unit, it could cause improper fuel mixture and timing adjustments, further exacerbating the overheating issue. Regular maintenance and monitoring of temperature sensors are essential to prevent such problems.
