Water Temperature Sensor

About this product

The Water Temperature Sensor (#89422-0R010), a crucial component of Toyota's Electrical EV Cooling and Engine-Fuel Radiator & Water Outlet systems, continuously monitors the engine's coolant temperature. As the engine operates, coolant circulates and the sensor registers its temperature to inform the car’s computer whether to increase or decrease engine cooling functions. This sensor is instrumental and, over time, may require replacement. An old or dysfunctional sensor may provide inaccurate readings, leading to engine overheating or inefficiency. Authentic Toyota parts are recommended for optimal compatibility, and they come with Toyota's genuine parts warranty. Ultimately, a well-functioning Water Temperature Sensor (#89422-0R010) contributes significantly to engine efficiency and safety, maintaining optimal engine temperature and preventing unforeseen engine damage.
