FUEL GAUGE UNIT CHECK
To 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
G
Point E: 110

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 CHECK
Connect fuel gauge unit to battery via test light (12 V-3.4
W). Immerse in water. Condition good if light goes off when
unit thermistor is in water and lights when unit is removed
from water.
Caution
w
After completing this test, wipe the unit dry and install
it in the fuel tank.
