| 1. Lower pressure in system. Disconnect a wire of the minus plug of the accumulator. |
| 2. Remove the block of the fuel pump. |
|
3. Disconnect a wire of the sensor and connect an ohmmeter to contacts 2 and 3. Measure resistance of the sensor when the lever of a measuring instrument is lowered completely down (a tank it is empty) about 110-115 Ohm and when the lever is completely lifted (a tank is full) about 2-3 Ohm. When moving lever resistance should change evenly. |
| 4. If necessary replace the sensor. |
