检查PCM输入电压: ①起动发动机,在无负荷(变速器换档杆置N或P位)条件下使发动机转速保持在3000r/min,直至散热器风扇转动。然后使发动机怠速运转至少1min,再进行路试。 ②测量PCM插接器端子B20与C16之间的电压。 ③完全踏下加速踏板再迅速松开
CHECK PCM INPUT VOLTAGE: (1) Start the engine and keep the engine speed at 3000r / min without load (transmission selector lever N or P position) until the radiator fan rotates. Then let the engine idle for at least 1min, then road test. ② Measure the voltage between the PCM connector terminals B20 and C16. ③ fully depress the accelerator pedal and then quickly release
