Fuel Gauge Sender: Testing and Inspection
FUEL GAUGE UNIT CHECK
Remove the fuel gauge unit from fuel tank.
Fuel Gauge Unit Resistance
1. Check that resistance value between the fuel gauge terminal and ground terminal is at the standard value when the fuel gauge unit float is between
point F (highest) and point E (lowest).
Standard value:
-
Point "F": 1 - 5 ohms
-
Point "E": 103 - 117 ohms
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 and B at point. Standard value:
-
A: 214 mm (8.42 inches)
-
B: 251 mm (9.88 inches)
2. Adjust the float arm to the standard value, then go to the thermistor check.
