Description

000 905 61 02 – Mercedes-Benz Engine Coolant Temperature Sensor
The Engine Coolant Temperature (ECT) sensor is a critical thermistor that monitors the internal operating temperature of the engine by measuring the thermal state of the coolant. This sensor sends real-time resistance-based data to the Engine Control Unit (ECU), which then adjusts the air-fuel mixture, ignition timing, and cooling fan activation to ensure optimal engine efficiency and prevent overheating. It also provides the data signal for the temperature gauge on the vehicle’s dashboard.
