Generally speaking engine sensors are the electro mechanical devices which monitor various engine parameters.
Car engine heat sensor.
The tip of the cts is probably located right next to the engine coolant.
The recorded temperature is then sent to the ecu which then adjusts the engine functions accordingly.
The coolant absorbs the heat produced by the combustion in the cylinders and then releases that heat to the atmosphere as it travels through the radiator.
The hottest component of your car is the engine because it s where combustion takes place.
Ironically an engine can t and won t function properly if it becomes too hot.
An engine uses different types of sensors that include are thermo couples resistance temperature detectors rtds and hall effect sensors.
The coolant temperature sensor s function.
This sensor monitors the temperature of the coolant circulating through your engine.
The ect sensor is usually located somewhere near the engine thermostat.
The sensor measures the temperature provided by the thermostat as well as the coolant itself.
