Fuel Gauge Unit Check

To check, remove fuel gauge unit from fuel tank.

Fuel Gauge Unit Float Height
Move float and measure the height A at point F (highest) and B point E (lowest) with float arm touching stopper.
Standard value:

Fuel Gauge Unit Inspection:

Main
A: 10.4 mm (0.41 ± 0.12 in.)
B: 119.5 mm (4.7 ± 0.12 in.)

Fuel Gauge Unit Inspection:

Sub
A: 3.0 ± 3 mm (0.12 ± 0.12 in.)
B: 126.7± 3 mm (5.0 ± 0.12 in.)

Fuel Gauge Unit Resistance
1. Check that resistance value between the fuel gauge terminal and ground terminal is at standard value when fuel gauge unit float is at point F (highest) and point E (lowest).
Standard value:

Fuel Gauge Unit Resistance:

Main
Point F: 2 ± 1 Ohm
Point E: 56.9 ± 1 Ohm

Sub
Point F: 2 ± 1 Ohm
Point E: 50.1 ± 1 Ohm
2. Check that resistance value changes smoothly when float moves slowly between point F (highest) and point E (lowest).
