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 FUEL SENDER GAUGE ASSEMBLY WARNING:
Perform the inspection in a well-ventilated area.
Do not perform the inspection near an open flame.
- Check that the float moves smoothly between F and E.
- Check the fuel sender gauge assembly voltage.
- Apply 5 V between terminals 2 and 3.NOTE:
- 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.
*a Component without harness connected
(Fuel Sender Gauge Assembly)*b Voltage Applied between Terminals - Measure the voltage according to the value(s) in the table below.
*a Component without harness connected
(Fuel Sender Gauge Assembly)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.
- Apply 5 V between terminals 2 and 3.
