Toyota Corolla Cross (2022-2024) Service Manual / Engine & Hybrid System / M20a-fks (fuel) / Fuel Pressure Sensor (for High Pressure) / Inspection

INSPECTION

PROCEDURE

1. INSPECT FUEL PRESSURE SENSOR

(a) Check the fuel pressure sensor output voltage.

(1) Apply 5 V between terminals 1 (VC) and 2 (E2).

NOTICE:

Be careful when connecting the leads as the 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 2 (E2).

HINT:

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

Voltage Applied between Terminals

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

Standard Voltage:

Tester Connection	Condition	Specified Condition
3 (PR) - 2 (E2)	Pressure not applied to fuel pressure sensor	Approximately 0.4 to 0.6 V*

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

If the result is not as specified, replace the fuel pressure sensor.
