In most vehicles, the coolant temperature sensor can be found near the engine thermostat. Where is the Engine Coolant Temperature Sensor Located?
COOLANT TEMPERATURE SWITCH VS SENSOR DRIVER
This data is also displayed to the driver via a temperature gauge in the dashboard.įor a more technical explanation of how the sensor works, check out this video: These functions include fuel metering, EGR operation, and fan engagement. This information is then relayed to the vehicle’s ECM (Engine Control Module), where it is used as an input when determining how best to regulate various engine functions. As its name would suggest, a vehicle’s coolant temperature sensor monitors the temperature of the coolant flowing throughout an engine. Coolant cycles through an engine’s cylinder heads and block, where it picks up heat that is produced as a byproduct of the combustion process.Ĭoolant is then directed to the radiator, where incoming airflow dissipates heat stored within the coolant. Internal combustion engines rely upon the use of a type of coolant to regulate operational engine temperatures.
