An engine coolant temperature sensor, or ECT sensor, is a small but crucial component in modern vehicles. Its role is to monitor the temperature of the engine coolant, which is essential in ensuring the vehicle’s optimal performance and preventing overheating.
A properly functioning ECT sensor provides accurate data to the engine’s computer, allowing it to adjust fuel injection, ignition timing, and other parameters to maintain the desired engine temperature range. This not only enhances engine efficiency and performance but also helps reduce emissions and extend the lifespan of the engine.
