FUEL GAUGE UNIT CHECKTo check, remove fuel gauge unit from fuel tank. (Refer to
GROUP 13F
- Fuel Tank.)
Fuel Gauge Unit Resistance
(1)Check that resistance value between the fuel gauge termi-
nal 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
If: 2 GPoint E: 110
It 7 Q
(2) Check that resistance value changes smoothly when float
moves slowly between point F (highest) and point E (low-
est).Fuel Gauge Unit Float Height
Move float and measure the height at point F (highest) and
point E (lowest) with float arm touching stopper.
Standard value:Point F: 18.6-21.6 mm (.73-.85 in.)
Point E: 193.4-196.4 mm (7.61-7.73 in.)
FUEL SENSOR CHECKConnect fuel gauge unit to battery via test light (12 V-3.4
W). Immerse in water. Condition good if light goes off whenunit thermistor is in water and lights when unit is removed
from water.
CautionwAfter completing this test, wipe the unit dry and install
it in the fuel tank.
