Critical Roles in Engine Management The data provided by the ECT sensor is utilized by the ECU across a wide array of crucial functions. More importantly, it often controls the electronic cooling fan.

Controlling Cooling Systems and Fan Activation Beyond fuel management, the ECT sensor is directly linked to the vehicle's cooling system. During a cold start, the engine requires a richer mixture (more fuel) to ensure smooth combustion and prevent stalling.
How the ECT Sensor Works and Its Core Function The ECT sensor is essentially a variable resistor, typically built as a thermistor, that changes its electrical resistance based on the temperature it detects. A faulty sensor can provide misleading data, which the ECU blindly follows, resulting in a cascade of performance issues.

The ECU interprets these voltage fluctuations as precise temperature readings. As the ECT sensor indicates the engine is reaching its optimal operating temperature, the ECU gradually adjusts the mixture to a leaner, more efficient ratio.
