Fuel Level Sensor: Testing and Inspection
FUEL LEVEL SENSOR CHECKRemove the fuel level sensor from fuel tank. (Refer to Fuel Tank.)
FUEL LEVEL SENSOR RESISTANCE
1. Check that resistance value between the fuel gauge terminal and ground terminal is at the standard value when the fuel level sensor float is between point
Standard Value:
- Point "F": 3 - 10.1
- Point "E": 90 - 110
2. Check that resistance value changes smoothly when the float moves slowly between point
3. If all checks are correct, go to fuel level sensor float height check. If any check is not correct, replace the fuel level sensor.
FUEL LEVEL SENSOR FLOAT HEIGHT
1. Move the float and measure height A at point "F" (highest) and B at point "E" (lowest).
Standard Value:
- A: 11.9 mm (0.47 inch)
- B: 195.2 mm (7.69 inches)
2. Adjust the float arm to the standard value, then go to the thermistor check.
