The Engine Coolant Temperature Sensor, often called ECT sensor or CTS (Coolant Temperature Sensor), is a crucial component in a vehicle's engine management system. It measures the temperature of the engine coolant and sends this information to the engine control unit (ECU) or the powertrain control module (PCM). This data helps the ECU adjust fuel injection, ignition timing, and other engine parameters to ensure optimal performance, fuel efficiency, and emission control.

If the coolant temperature sensor malfunctions or fails, it can lead to issues such as incorrect fuel mixture, poor engine performance, increased emissions, or problems with starting the engine. A failing sensor might cause the engine to run too rich or too lean, impacting fuel efficiency and potentially causing damage to the engine over time.
