故障现象一辆解放J6型牵引车(车型为CA4250P66K2T3A3E,装配锡柴CA6DL2-350E3电控高压共轨柴油发动机,发动机采用博世电控系统),出现发动机动力不足,最高转速只能达到1500 r/min,而且发动机故障灯常亮的现象。故障诊断因为发动机故障灯点亮,于是就首先连接故障检测仪读取故障代码,结果调得的故障代码有:P0192——轨压传感器信号电压超下限;P1022——油门踏板传感器信号1低于最低限值。根据故障代码及其含义分析,认为故障出在油门踏板和轨压传感器上,于是就更换了油门踏板和轨压传感器,然后清
Symptoms A Jiefang J6 tractor (model CA4250P66K2T3A3E, equipped with Xichai CA6DL2-350E3 electric high-pressure common rail diesel engine, the engine adopts Bosch electric control system), the engine power shortage, the maximum speed can only reach 1500 r / min , And the engine fault light is always on phenomenon. Fault diagnosis Because the engine fault light is on, the fault detector is first connected to read the fault code. The result is the fault code: P0192 - rail voltage sensor signal over the lower limit; P1022 - throttle pedal sensor signal 1 is below Lowest limit. According to the analysis of the fault code and its meaning, that the fault lies in the accelerator pedal and rail pressure sensor, so replace the accelerator pedal and rail pressure sensor, and then clear
