Automotive Temperature Sensor

The water temperature sensor is the core component of the car cooling system. Its core component is the NTC thermistor, which is installed on the engine cylinder head or water channel. This component looks simple, but it is actually very critical to engine control. It will directly affect the ECU’s adjustment of the injection amount and ignition timing.

The EGT sensor is responsible for reading the temperatures of the aftertreatment system components such as inlet DOC, inlet DPF, outlet DPF, inlet SCR, outlet SCR, stb., and sending this information back to the ECM to maintain proper temperatures that control the aftertreatment system to reduce the harmful emissions.
