DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Memory	Note
P107A2A	Fuel Rail Pressure Sensor (Low) / Fuel Rail Pressure Sensor "B" Signal Stuck in Range	When the target fuel pressure for the low pressure side changes, the change in the fuel pressure sensor (for low pressure side) value is abnormal (2 trip detection logic).	· Leak of fuel · Fuel pump control ECU · Fuel pressure sensor (for low pressure side) · Fuel pump (for low pressure side) · Fuel main valve assembly · ECM	Comes on	DTC stored	SAE: P107B
P107A64	Fuel Rail Pressure Sensor (Low) / Fuel Rail Pressure Sensor "B" Signal Plausibility Failure	When the fuel pump on the low pressure side is operated at the maximum during a fuel cut, the low pressure side fuel pressure is higher or lower than threshold (2 trip detection logic).	· Leak of fuel · Fuel pump control ECU · Fuel pressure sensor (for low pressure side) · Fuel pump (for low pressure side) · Fuel main valve assembly · ECM	Comes on	DTC stored	SAE: P107B

MONITOR DESCRIPTION

Fuel Pressure Sensor Stuck Monitor: If the 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 P107A2A.

Fuel Pressure Sensor Correlation Monitor (Fuel Cut): If the 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 P107A64.

MONITOR STRATEGY

Required Sensors/Components (Main)	Fuel pressure sensor (for low pressure side)
Required Sensors/Components (Related)	ECM (atmospheric pressure sensor)
Frequency of Operation	Continuous: Stuck monitor Once per driving cycle: Correlation monitor
