Khảo sát kiểm tra cảm biến nhiệt độ nước ô tô Engine CoolantTemperature (ECT) Sensor ‪@kythuatxe9571‬

#hocdienchancoban #hocdienoto #technical #diagnosis he ECT responds to change in engine coolant temperature. By measuring engine coolant temperature, the ECM knows the average temperature of the engine. The ECT is usually located in a coolant passage just before the thermostat. The ECT is connected to the THW terminal on the ECM. The ECT sensor is critical to many ECM functions such as fuel injection, ignition timing, variable valve timing, transmission shifting, etc. Always check to see if the engine is at operating temperature and that the ECT is accurately reporting the temperature to the ECM Cám ơn các bạn đã theo dõi.
