DTC P107A-11: Fuel Rail Pressure Sensor (Low) / Fuel Rail Pressure Sensor "B" Circuit Short to Ground [12/2023 - ]: Description

WARNING: This page is about a different car, the 2024 Lexus TX 550h+. However, it is still accessible from the selected car via links, so may be relevant.

The fuel pressure sensor (low pressure side) replaces the fuel pressure with electrical signals and outputs them to the ECM. The ECM controls the optimal fuel pressure for the operation conditions to reduce the fuel pump power consumption and improve fuel economy.

HINT:

When a DTC is output, check the Data List item "Fuel Pressure (Low) / Fuel Pressure 2" using the GTS.

Refer to DATA LIST / ACTIVE TEST [12/2023 - ]

DTC No.	Fuel Pressure (Low) / Fuel Pressure 2	Malfunction
P107A-11	Approximately 0 kPag	Short in PFL circuit to ground Short in PFL circuit to EPFL circuit Open in VCPF circuit

If the Data List displays a normal value, the normal value may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.
