Fuel Level Sensor: Testing and Inspection

FUEL LEVEL SENSOR CHECK
Remove the fuel pump module and the 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 "F" (highest) and point "E" (lowest).

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 "F" (highest) and point "E" (lowest).
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) with the float arm touching stopper.

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.
