Fuel Gauge Sender: Testing and Inspection
Fuel Gauge Unit RemovalRemove the fuel pump module and then remove the fuel gauge unit. (Refer to 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
Standard value:
- Point "F": 3-5 Ohm
- Point "E": 110 - 112 Ohm
2. Check that resistance value changes smoothly when the float moves slowly between point
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
Standard value:
- A: 180.3 mm (7.10 inches)
- B: 18.8 mm (0.74 inch)
2. Adjust the float arm to the standard value, then go to the thermistor check.
