故障现象一辆2011款沃尔沃S60轿车,行驶里程约为1.8万km,因发动机故障灯异常点亮而进厂维修。故障诊断连接沃尔沃专用检测仪VIDA读取故障代码,调得2个故障代码,分别为“ECM-P008762:油道系统压力过低,信号比较故障”和“ECM-P008753:油道系统压力过低,模块编程关闭”。查看发动机运行状态下的数据流,怠速状态下低压燃油压力传感器的数值为620 kPa左右;踩下加速踏板,低压燃油压力传感器的数值在620 kPa～650 kPa波动,基本正常。此外,发动机的各项数据基本都在正常范
Failure phenomenon A 2011 Volvo S60 sedan, mileage of about 18,000 km, due to anomalies engine fault light into the factory maintenance. Fault Diagnosis Connect Volvo-specific VIDA to read the fault codes and set them to 2 fault codes, “ECM-P008762: OIL SYSTEM PRESSURE LOW, SIGNAL COMPATIBILITY” and “ECM-P008753: Low pressure, module programming off ”. Check the data flow under the running condition of the engine. The value of the low-pressure fuel pressure sensor is about 620 kPa at idle state. When the accelerator pedal is depressed, the value of the low-pressure fuel pressure sensor fluctuates from 620 kPa to 650 kPa, which is basically normal. In addition, the engine of the basic data are in normal range
