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 of a butterfly valve changed, or there are suspicions that adjustment of turns of idling was broken (for example, the screw of idling was turned out from a chamber of a butterfly valve), the car should be handed over in service of car service.
Check
| PERFORMANCE ORDER |
| 1. Check operation of the regulator. For this purpose on the diagnostic socket connect a crossing point conclusions of TE1 and E1. Bring turns to 1300 rpm, later 10 sec. release the gate and check idling turns, – turns have to fall to normal (see subsection 2.1). |
| 2. Disconnect a vacuum hose and reliably muffle. Start the engine, – now turns have to be 500 rpm, and the engine can decay. If turns are higher, in the regulator there is an air suction. |
| 3. Establish a hose and remove a crossing point. |
| 4. Disconnect the socket from the regulator. |
| 5. Check resistance between couples of conclusions + B and RSC, + B and RSO. |
|
6. At food of conclusions + B and RSO the valve of the regulator has to open. |
| 7. If resistance differ from normal, replace the regulator. |
| 8. Check operation of the valve according to the scheme, observing polarity of connection. |
|
9. At food of these conclusions the valve of the regulator has to be closed. |
|
Replacement
| PERFORMANCE ORDER |
|
|
1. Unscrew screws (are specified by shooters) and remove the regulator and laying. If necessary remove the gate case. |
| 2. If the regulator changes, remove and rearrange the thermal vacuum valve on the new regulator (if it is provided). |
|
Installation
Installation is carried out upside-down.
