Fuel Pressure Sensor Stuck Monitor
If the No. 2 fuel pressure sensor (for low pressure side) value does not follow the change in the target low 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 DTC P107A-2A.
Fuel Pressure Sensor Correlation Monitor (Fuel Cut)
If the No. 2 fuel pressure sensor (for low pressure side) value is less than or higher than the threshold value when the fuel pump on the low pressure side is operated at the maximum during a fuel cut, 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 DTC P107A-64.
