Fuel Rail / System Pressure - Too Low (P008700)

DESCRIPTION The high-pressure direct injection fuel system consists of a spill control valve, check valve, fuel relief valve, fuel pressure sensor (for high pressure side), fuel pump assembly (for high pressure side) and direct fuel injector assemblies...

Low Pressure Fuel System Pressure - Too Low (P008A00)

DESCRIPTION In order to supply the optimal fuel pressure according to the driving conditions and usage environment, the variable fuel system sends a drive signal from the ECM to the fuel pump control ECU, steplessly performing variable control of the fuel pump (for low pressure side) and receiving feedback about the fuel pressure (for low pressure side) from the No...
