Toyota Yaris: Fuel Pressure Sensor / Inspection

Toyota Yaris XP210 (2020-2025) Reapir and Service Manual / Engine & Hybrid System / G16e-gts (fuel) / Fuel Pressure Sensor / Inspection

INSPECTION

PROCEDURE

1. INSPECT NO. 2 FUEL PRESSURE SENSOR

(a) Check the No. 2 fuel pressure sensor output voltage.

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

NOTICE:

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.

Component without harness connected

(No. 2 Fuel Pressure Sensor)

Voltage Applied between Terminals

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

Standard Voltage:

Tester Connection	Condition	Specified Condition
D27-2 (PFL) - D27-3 (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.

*a	Component without harness connected (No. 2 Fuel Pressure Sensor)
