Fuel Rail Pressure Sensor "A" Circuit Short to Ground (P019011)

DESCRIPTION

The fuel pressure sensor (for high pressure side) is installed on the fuel delivery pipe (for high pressure side). The fuel pressure sensor (for high pressure side) changes the fuel pressure for high pressure side into an electrical signal and sends the signal to the ECM. Then the ECM controls the pump discharge using this feedback to maintain the fuel's target pressure between 2 and 25 MPa (20 and 255 kgf/cm2).

Cylinder 1 Injector "A" Circuit Open (P020113-P020613,P062D13)

DESCRIPTION

The D-4S system has two fuel injection systems. One is an in-cylinder direct injection system that directly injects pressurized fuel into the combustion chamber. The other is an intake port injection system. The ECM determines which fuel injection system to use in accordance with the engine conditions. The direct injection system uses an injector driver (EDU) built into the ECM to rapidly operate the fuel injector assemblies (for direct injection). It converts injection request signals from the ECM to high-voltage and high-current injector-drive signals that drive the fuel injector assemblies (for direct injection).

MONITOR DESCRIPTION

The fuel injection sequence occurs in numerical order from No. 1 to No. 6.

The ECM monitors the Injector Driver (EDU) at all times. If drivers or fuel injector assembly (for direct injection) are malfunctioning, the EDU sends fuel injector assembly (for direct injection) operation condition signals (fail signals) to the ECM. When the ECM receives the signals, the ECM stops the fuel injection control of the appropriate cylinders, cuts voltage to the appropriate D INJ relay, and illuminates the MIL.
