Engine coolant temperature sensor What it is A sensor that measures the temperature of the engine coolant and provides real time data to the engine control system. Why you need it Accurate coolant temperature readings help the engine control module adjust fuel delivery, ignition timing, and cooling fan operation for proper engine performance and efficiency. A failing or erratic sensor can lead to incorrect readings, affecting driveability and fuel economy. Direct fit and compatibility Designed as a direct replacement that matches factory specifications and installs like the original unit. Compatible with vehicles that use the OEM engine coolant temperature sensor with the same specifications. Quality and materials Designed and manufactured with modern tooling to ensure high quality and reliability. Replacement parts are produced to the same specifications as the OEM and use better, more durable materials than those provided by the OEM. Installation Direct fit replacement that installs seamlessly, requiring no modifications or special tools beyond standard hand tools. Use scenarios - Replacing a failing ECT sensor during routine maintenance or diagnostic service on a typical passenger vehicle. - Restoring accurate coolant temperature readings after diagnostic trouble codes indicate abnormal data. - Replacing in high mileage or aging engines to maintain proper engine management and prevent related performance issues.
