Fuel Level Sensor: Testing and Inspection

FUEL LEVEL SENSOR CHECK
Remove the fuel pump module and remove the fuel level sensor.

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 - 5 ohms
- Point "E": 110 - 112 ohms


2. Check that resistance value changes smoothly when the float moves slowly between point.
3. If no problems are found in steps above, go to "Fuel level sensor float height" check. If any problem is found, replace the fuel level sensor.

Fuel Level Sensor 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 Thermistor check.
