Fuel Gauge Sender: Testing and Inspection

FUEL GAUGE UNIT CHECK
Remove the fuel pump module and the remove the fuel gauge unit. (Refer to Fuel Tank.)




Fuel Gauge Unit Resistance
1. Check that resistance value between terminals 2 and 1 is at the standard value when the fuel gauge unit float is between point "F" (highest) and point "E" (lowest).

Standard value:
- Point "F": 3 ± 0.8 Ohm
- Point "E": 110 ± 2.5 Ohm

2. Check that resistance value changes smoothly when the float moves slowly between point "F" (highest) and point "E" (lowest).
3. If all checks are correct, go to fuel gauge unit float height check. If any check is not correct, replace the fuel gauge unit.




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

Standard value:
- A: 24.1 ± 2 mm (0.95 inch)
- B: 151.6 ± 2 mm (5.97 inches)

2. Adjust the float arm to the standard value, then go to the thermistor check.
