Fig. 19.7. Checking the resistance of the fuel level sensor: 1 – contact of the fuel level sensor in the tank; 2 – ground contact
2. Check that the resistance between the fuel level sensor contact and the ground contact matches the nominal value (Fig. 19.7) when the sensor float is at the highest point (F) and the lowest point (E).
Nominal resistance, Ohm:
- point F - 7.9-14.6;
- point E - 107.9–118.9.
3. Check the smoothness of the resistance change when slowly moving the float between the highest point F and the lowest point E.
Fig. 19.8. Checking the smoothness of the resistance change when slowly moving the float between the highest point F and the lowest point E: 1 – point F (full tank); 2 – point E (empty tank)
4. By moving the float, measure the height B (Fig. 19.8) at point E (lowest) and the height A at point F (highest).
Nominal value, mm:
- A = 142.4;
- B = 28.
