Monitor Description

To monitor fuel pressure drops in the direct fuel injection, the ECM measures the fuel pressure using the fuel pressure sensor.

If the sensor value is lower than the target fuel pressure value, the ECM interprets this as a malfunction. The ECM illuminates the malfunction indicator lamp (MIL) and sets the diagnosis trouble code (DTC) immediately.
