5.14.12. Check and replacement of the regulator of idling

The regulator consists of the bipolar step electric motor and the conical valve connected to it. On a signal of an electronic control unit the electric motor moves with the engine the valve, changing thereby the section of the air channel through passage.
It will be required to you: the screw-driver with a crosswise edge, a tester.
1. At the switched-off ignition wring out a clamp of a block of a motor plait of wires...
2... also disconnect a block from the regulator.
3. Include ignition and measure by a tester in the voltmeter mode tension between a conclusion And blocks and "mass" of the car.
4. Repeat measurement serially for other conclusions of a block (B, C and D). Indications of a tester for these four measurements have to be within 0,4–12 Century.
5. Switch a tester to the mode of an ohmmeter and measure resistance between conclusions of A and the D regulator, and then between conclusions of B and C. Resistance has to be within (53±5,3) Ohms.
6. For replacement of the regulator turn out two screws of its fastening to throttle knot...
7.... also take the regulator from an opening of throttle knot.

Pay attention that connection is condensed with a rubber ring 1. Do not try to extend or press the valve 2 regulators — it can put the regulator out of action.

8. Clear a saddle, the air channel in throttle knot and a surface under a sealing ring of the regulator of pollution.
9. Oil a sealing ring engine and install the regulator as it should be, the return to removal. Screws of fastening of the regulator tighten the moment of 3-4 N · m.
