THE CONTROL AIR VALVE OF IDLING (FOR ENGINES 1,6 AND 1,8 L)

Prevention

Turns of idling of the engine are established by the manufacturer and at operation in normal conditions their adjustment is not required. However, if replacement of the chamber of a butterfly valve was made or there are suspicions that adjustment of turns of idling was broken (for example, the screw of idling was turned out from the butterfly valve chamber), it is necessary to hand over the car in car-care center service, or in a specialized workshop.

PERFORMANCE ORDER
1. Put the car on the hand brake, a control lever of a check point establish in neutral provision (manual transmission) or in the situation Park (automatic transmission), block driving wheels. Connect a tachometer to IG conclusion (–) the diagnostic socket (see fig. Tachometer connection to IG conclusion (–) the diagnostic socket). Start the engine and warm up to normal working temperature. Consider turns of idling and compare to standard value in subsection 5.1.
2. A crossing point close накоротко conclusions of TE1 and Е1 the diagnostic socket.
3. Turns of idling should increase from 1000 rpm to 1200 rpm within 5 seconds, and then decrease to the initial. If turns of idling raise and decrease as is specified above, the valve is serviceable. If the engine behaves differently, check resistance of the air valve.
4. Remove a crossing point.
5. Disconnect the valve socket.

If resistance in norm, the valve is serviceable and it is necessary to check conducting or the control unit. If resistance differs from standard, the valve replace.

7. Connect to the valve the disconnected socket.

Replacement

PERFORMANCE ORDER
1. Remove the butterfly valve chamber.

Prevention

Access to the control air valve is complicated, therefore for the correct installation of the new valve it is recommended to remove the butterfly valve chamber.
