General Description
GDI(Gasoline Direct Injection) ECM calculates controlled variable with the signal from fuel rail pressure sensor to control optimized RPM and rail pressure. ECM sends it to IDB(Injector Drive Box). IDB operates fuel pressure valve according to controlled variable from ECM.
Two high pressure pumps pressurize fuel supplied from low pressure pump. Two fuel rail pressure regulator control fuel rail pressure at 35 - 150bar according to engine RPM.
DTC Description
If there is open or short in control circuit(B2-ON) between ECM and IDB, ECM sets DTC P2632.
