Title: A25A-FXS (FUEL): FUEL SENDER GAUGE ASSEMBLY (w/o Canister Pump Module): INSPECTION; 2019 - 2020 MY RAV4 HV [11/2018 - 08/2020]

INSPECTION

PROCEDURE

1. INSPECT FUEL SENDER GAUGE ASSEMBLY

CAUTION:

Perform the inspection in a well-ventilated area.

Do not perform the inspection near an open flame.

(a) Check that the float moves smoothly between F and E.

(b) Check the fuel sender gauge assembly voltage.

(1) Apply 5 V between terminals 2 and 3.

NOTICE:

  • Be careful when connecting the leads, as the fuel sender gauge assembly may be damaged if the leads are connected to the wrong terminals.
  • Do not apply more than 6 V to terminals 2 or 3.

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

Float Level

Specified Condition

1 - 2

F

4.255 to 4.605 V*

Between F and E

0.345 to 4.605 V* (Gradually changes)

E

0.345 to 0.695 V*

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

Output voltage (F) = (0.851 x Voltage applied to terminals) to (0.921 x Voltage applied to terminals)

Output voltage (E) = (0.069 x Voltage applied to terminals) to (0.139 x Voltage applied to terminals)

If the result is not as specified, replace the fuel sender gauge assembly.
