- Remove the fuel level sensor from the fuel tank.
- Check that the resistance between the fuel level sensor terminal and «weight» corresponds to the nominal value when the float is at the upper F and lower E points (pic. 19.70).
Pic. 19.70. Checking the resistance of the fuel level sensor
Nominal resistance of the fuel level sensor:
- in the upper position of the float F: 7.9-14.6 ohms
- in the lower position of the float E: 107.9-118.9 Ohm
- Check the smoothness of the change in resistance when moving the float from the bottom position to the top.
- Check the height of the float of the fuel level sensor, for which move the float until it touches the stops and measure the distance (A) at the top point F and the distance (IN) at the bottom E (pic. 19.71).
Pic. 19.71. Measuring the float height of the fuel level sensor
Nominal float height:
- in the top position (A): 142.4 mm
- in the down position (IN): 28 mm
