DTC P107A-11: Fuel Rail Pressure Sensor (Low) Circuit Short to Ground [11/2016 - ]: Description

Fig 1: Fuel Pressure / Voltage Graph

Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

The fuel pressure sensor (for 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.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Memory	Note
P107A-11	Fuel Rail Pressure Sensor (Low) Circuit Short to Ground	The fuel pressure sensor (for low pressure side) output voltage is less than 0.43 V for 3 seconds or more (1 trip detection logic).	Open or short in fuel pressure sensor (for low pressure side) circuit Fuel delivery pipe RH (fuel pressure sensor (for low pressure side)) ECM	Comes on	DTC stored	SAE Code: P107C DTC for Mexico Models: - Applies

HINT:

When this DTC is output, check the fuel pressure (for low pressure side) in the Data List. Enter the following menus: Powertrain / Engine / Data List / Fuel Pressure (Low).

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

If the Data List values is normal it may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.
