Monitor Description

Fuel Pressure Sensor Stuck Monitor 

• If the fuel pressure sensor value does not follow the change in the target high pressure side fuel pressure, it is judged as a malfunction. If this malfunction is detected in 2 consecutive driving cycles, the ECM will illuminate the MIL and store this DTC.

Fuel Pressure Sensor Correlation Monitor with Barometric Pressure 

• If the fuel pressure sensor value is less than or higher than the threshold value when a cold start is performed after the engine has been warmed up and then stopped, it is judged as a malfunction has occurred. If this malfunction is detected for 2 consecutive driving cycles, the ECM will illuminate the MIL and store this DTC.
