| 1. Disconnect from the valve колодку with wires. |
| 2. Connect an ohmmeter to contacts of the valve and measure its resistance, it should be equal 22–30 Ohm. If resistance differs from specified, replace the valve. |

3. Check up a valve food. For this purpose connect the indicator of pressure with a light-emitting diode to contact 1 колодки, disconnected from the valve and "weight" of the engine. Include a starter, the light-emitting diode should burn; if does not burn, eliminate breakage in conducting. |
