1. Check that resistance value between the fuel gauge terminal and ground terminal is at standard value when the fuel gauge unit float is at point F (highest) and point E (lowest).
Standard value:
POINT F: 2 ± 1 Ohm
POINT E: 50.1 ± 1 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, proceed to fuel gauge unit float height check. It any check is not correct, replace the fuel gauge unit
