The prevention Turns of idling of the engine are established
The manufacturer and at operation in normal conditions of their adjustment does not require. However, if the chamber throttle заслонки varied, or there are suspicions that adjustment of turns of idling was broken (for example, the idling screw was turned out from the chamber throttle заслонки) it is necessary to hand over the car in car-care centre service.
Check
| PERFORMANCE ORDER |
| 1. Check up regulator work. For this purpose on a diagnostic socket connect a crosspiece conclusions ТЕ1 and Е1. Finish turns to 1300 rpm, later 10 сек release заслонку and check up idling turns, – turns should fall to normal (subsection 2.1 see). |
| 2. Disconnect a vacuum hose and reliably muffle. Start the engine, – now turns should be 500 rpm, and the engine can decay. If turns above in a regulator is available подсос air. |
| 3. Establish a hose and remove a crosspiece. |
| 4. Disconnect from a regulator a socket. |
| 5. Check up resistance between steams of conclusions +B and RSC, +B and RSO. |
|
6. At a food of conclusions +В and RSO the regulator valve should open. |
| 7. If resistance differ from normal a regulator replace. |
| 8. Check up valve operation under the scheme, observing polarity of connection. |
|
9. At a food of these conclusions the regulator valve should be closed. |
|
Replacement
| PERFORMANCE ORDER |
|
|
1. Turn away screws (are specified by arrows) and remove a regulator and a lining. If necessary remove the case заслонки. |
| 2. If the regulator varies, remove and rearrange the thermovacuum valve on a new regulator (if it is provided). |
