4. Squeeze clamps and disconnect from a nozzle of a block of a plait of wires.

Blocks with a plait of wires are removed in a special cover.

5. Measure by an automobile tester nozzle winding resistance in the mode of an ohmmeter. At 20 °C it has to make 14 Ohms. If resistance of a winding of a nozzle does not meet standard, replace a nozzle as it is not maintainable.

In a form of the sprayed torch of fuel and on tightness you carry out check of a nozzle at specialized service stations as such check directly on the car is very fire-dangerous.
