What does an exhaust temperature sensor do?

2026-07-16

An exhaust temperature sensor (EGTS) is a critical component in modern engine exhaust systems, with core functions as follows:

  1. ‌Real-time temperature monitoring‌
    It accurately measures the exhaust gas temperature and converts the data into an electrical signal, which is transmitted to the Engine Control Unit (ECU).
  2. ‌Engine performance optimization‌
    The ECU adjusts fuel injection, ignition timing and other parameters based on the temperature data, optimizing combustion efficiency, improving fuel economy and reducing pollutant emissions.
  3. ‌Key component protection‌
    It safeguards critical parts such as turbochargers, catalytic converters, and Diesel Particulate Filters (DPF) from overheating. When the temperature exceeds the set threshold, it triggers an alarm to prevent component damage.
  4. ‌Aftertreatment system management‌
    It supports DPF regeneration, Selective Catalytic Reduction (SCR) dosing calculation and other processes, ensuring the vehicle complies with regional emission regulations.
