ENGINE CONTROL SYSTEM
CYLINDER TEMPERATURE SENSOR The cylinder temperature sensor is installed on the cylinder (top side) and used to detect the cylinder temperatureThis is thermistor type sensor (resistance of which changes depending on temperature) and inputs signal to the ECM as voltage valueThis signal is used to compensate the fuel injection time duration, ignition timing, etcThis sensor is also used to detect engine over-heat as the ECM detects both the temperature and temperature change gradient (temperature rise VS time)(k)
