Monitor Description

Fuel Pressure Sensor (for High Pressure Side) Stuck Monitor 

If the fuel pressure sensor (for high pressure side) 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 assembly will illuminate the MIL and store this DTC.

Fuel Pressure Sensor (for High Pressure Side) Correlation Monitor with Barometric Pressure 

If the fuel pressure sensor (for high pressure side) 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 assembly will illuminate the MIL and store this DTC.
