2.4 节气门位置(TP)传感器及其检修节气门位置(TP)传感器是三导线型可变电阻式传感器,如图21所示,安装于节气门体上,由节气门轴操纵。节气门位置(TP)传感器用来向PCM提供与节气门开度相对应的电信号,PCM利用该信号计算燃油喷射量和点火正时,并用于液力变矩器、换档指示灯、EVAP燃油蒸发系统、废气再循环和空调等的控制。TP传感器的信号电压在节气门关闭时为1.0V,在节气门全开
2.4 THROTTLE POSITION (TP) SENSOR AND ITS SERVICE The Throttle Position (TP) sensor is a three-wire, variable-resistance sensor mounted on a throttle body as shown in Figure 21 and operated by a throttle shaft. The throttle position (TP) sensor is used to provide the PCM with an electrical signal corresponding to the throttle opening. The PCM uses this signal to calculate the fuel injection amount and ignition timing and is used in the torque converter, shift indicator, EVAP Fuel evaporation system, exhaust gas recirculation and air conditioning control. The TP sensor’s signal voltage is 1.0V when the throttle is closed and fully open at the throttle
