| 1. Fill in a full tank of fuel. | 
 
 | 2. Remove back sitting and a protective cover of a fuel tank. | 
 
 | 3. Disconnect the electric socket from a fuel tank. | 
 
 |  | 4. Using an ohmmeter, check resistance between contact ми 1 and 2 electric sockets. At a full tank resistance between contacts 1 and 2 should make 2–3 Ohms.
 | 
 
 | 5. Connect into place the electric socket and spend fuel almost to an empty tank. | 
 
 | 6. Measure resistance between contacts 1 and 2 electric sockets which should make 110–115 Ohm on an empty fuel tank. | 
 
 |  | 7. If resistance of the fuel level sensor does not correspond to demanded values, replace the sensor. It is possible to measure resistance of the sensor also, having removed the sensor from a fuel tank and moving it a hand. |
