EC-22 < SYSTEM DESCRIPTION > [VQ35DE] COMPONENT PARTS In the driving range, ECM turns ON the electronically-controlled engine mount control solenoid valve and cuts manifold pressure applied on the electronically-controlled engine mount. This increases damping force of the electronically-controlled engine mount and reduces vibrations generated during driving. Engine Coolant Temperature Sensor INFOID:0000000009178013 The engine coolant temperature sensor is used to detect the engine coolant temperature. The sensor modifies a voltage signal from the ECM. The modified signal returns to the ECM as the engine coolant temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the ther- mistor decreases as temperature increases. <Reference data> *: These data are reference values and are measured between ECM terminals. Engine Oil Pressure Sensor INFOID:0000000009178014 The engine oil pressure (EOP) sensor is detects engine oil pressure and transmits a voltage signal to the ECM. Engine Oil Temperature Sensor INFOID:0000000009178015 The engine oil temperature sensor is used to detect the engine oil temperature. The sensor modifies a voltage signal from the ECM. The modified signal returns to the ECM as the engine oil tempera- ture input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.
