Fuel Gauge Unit Check

To check, remove fuel gauge unit from fuel tank.

Float Height Of Fuel Gauge Unit:

Float Height of Fuel Gauge Unit
1. Move float and measure the height at point F (highest) and point E (lowest) with float arm touching stopper.
Point F 21.3 - 24.3 mm (.84 - .96 in.)
Point E 199.2 - 202.2 mm (7.84 - 7.96 in.)

Fuel Sensor Inspection:

Standard Resistance of Fuel Gauge Unit
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:
Point F 3 ± 2 Ohm
Point E 110 ± 7 Ohm
2. Check that resistance value changes smoothly when float moves slowly between point F (highest) and point E (lowest)
