Inspection [10/2022 - ]: Procedure

WARNING: This page is about a different car, the 2025 Toyota Highlander, 2024 Toyota Highlander, and 2023 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.

INSPECT NO. 2 FUEL PRESSURE SENSOR

Check the No. 2 fuel pressure sensor output voltage.

Apply 5 V between terminals 1 (VC) and 3 (E2).

*a	Component without harness connected (No. 2 Fuel Pressure Sensor)
*b	Voltage Applied between Terminals

NOTE:

Be careful when connecting the leads, as the No. 2 fuel pressure sensor may be damaged if the leads are connected to the wrong terminals.
Do not apply more than 6 V to terminals 1 (VC) or 3 (E2).

HINT:

If a stable power supply is not available, connect 4 nickel-metal hydride batteries (1.2 V each) or equivalent in series.

Measure the voltage according to the value(s) in the table below.

Standard Voltage

Tester Connection	Condition	Specified Condition
2 (PFL) - 3 (E2)	Pressure not applied to No. 2 fuel pressure sensor	Approximately 0.57 to 0.95 V*

*: The output voltage changes depending on the voltage applied to the terminals.

If the result is not as specified, replace the No. 2 fuel pressure sensor.
