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 camera of a butterfly valve was made or there are suspicions on the fact that adjustment of turns of idling was broken (for example, the screw of idling was turned out from the camera of a butterfly valve), then the car should be handed over in service of car service, or in a specialized workshop.
Check

| PERFORMANCE ORDER |
| 1. Put the car on the emergency brake, establish a control lever of the check point in neutral situation (manual transmission) or in situation Park (automatic transmission), block driving wheels. Connect a tachometer to IG conclusion (–) of the diagnostic socket (see rice. Connection of a tachometer to IG conclusion (–) the diagnostic socket). Start the engine and warm up up to the 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 E1 of the diagnostic socket. |
| 3. Turns of idling have to increase from 1000 rpm up to 1200 rpm within 5 seconds, and then decrease to initial. If turns of idling raise and decrease as it is stated above, the valve is serviceable. If the engine behaves differently, then check resistance of the air valve. |
| 4. Remove a crossing point. |
| 5. Disconnect the valve socket.
|
|
6. Measure resistance between an average conclusion and each of two other conclusions. Compare valve resistance to the value specified in subsection 5.1. If resistance is normal, then the valve is serviceable and it is necessary to check conducting or the control unit. If resistance differs from standard, then replace the valve. |
7. Connect the disconnected socket to the valve. |
|
Replacement
| PERFORMANCE ORDER |
| 1. Remove the camera of a butterfly valve. |
Prevention
Access to the control air valve is complicated therefore for the correct installation of the new valve it is recommended to remove the camera of a butterfly valve.
|
|

Start the engine and warm up before establishment of normal working temperature and turns of idling. Turn on the conditioner. |
| 2. A crossing point close накоротко conclusions of TE1 and E1 of the diagnostic socket. |
| 3. Turns of idling have to increase from 1000 rpm up to 1200 rpm within 3 seconds after a peremykaniye of conclusions, and then decrease to initial. 15 seconds later check idling turns again, speed has to exceed approximately on 100 rpm normal value. If turns of idling change as it is described above, then the valve is serviceable. If turns increase more than by 100 rpm, then adjust the range of turns of idling, rotating the adjusting screw. If turns of the engine do not change or decrease, then check compensation valve resistance. |
| 4. Remove a crossing point. |
| 5. Disconnect the socket from the valve.
|
|
6. Measure resistance between conclusions. Resistance has to be within 30–34 Ohms. If resistance is normal, then the valve is serviceable and it is necessary to check conducting or the control unit. If resistance differs from standard, then replace the valve (see below). |
