Fuel Level Sensor Check

FUEL LEVEL SENSOR CHECK

FUEL LEVEL SENSOR RESISTANCE

1. Remove the fuel level sensor. Removal and Replacement.





2. Check the resistances between fuel level sensor main terminals 1 and 2 as well as sub terminals 1 and 2 of the fuel pump module, respectively.
Standard value:

3. Check that resistance value changes smoothly when the float moves slowly between points.
4. If all checks are correct, go to fuel unit height check. If any check is not correct, replace the fuel pump module or fuel level sensor (sub).

FUEL LEVEL SENSOR FLOAT HEIGHT

1. Remove the fuel level sensor. Removal and Replacement.









2. Move the float and measure height A at point "F" (highest) and B at point "E" (lowest).
Standard value:

3. If any check is not correct, replace the fuel pump module or fuel level sensor (sub).
