5.2.9.2.4. The valve of a regulator of turns of idling
THE GENERAL DATA

The valve of a regulator of turns of idling (the ISC-valve, on cars 1988-92) or the control air valve of idling (the IAC-valve, on cars with 1993г.).
The prevention

Turns of idling of the engine are established by the manufacturer and at operation in normal conditions of their adjustment it is not required. However, if replacement of the chamber throttle заслонки was made 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.


Check

PERFORMANCE ORDER
1. At deenergizing of ignition the valve of a regulator of turns of idling (ISC-valve) should publish click.
2. Disconnect an ISC-valve socket.
3. A crosspiece submit pressure on conclusions В1 and В2. Connect to weight conclusions S1 and S2, then S3 and S4. Плунжер the valve it should be put forward, i.e. the valve should be closed.
4. A crosspiece submit pressure on conclusions В1 and В2. Connect to weight conclusions S3 and S4, then S1 and S2. Плунжер the valve it should be involved, i.e. the valve should open.
5. If the valve does not work, replace it.
6. Check up resistance between conclusions B1 and S1, B1 and S3, then between conclusions B2 and S2, B2 and S4. Results compare with specified in specifications (subsection 5.2.1 see).
7. If resistance in norm the valve is serviceable (in this case it is necessary to search for malfunction in conducting from block ECM).
8. If resistance differs from standard the valve replace.
9. Attach a socket.

Replacement

PERFORMANCE ORDER
1. If access to screws is complicated, remove the case заслонки.
2. Turn away fastening screws (are specified by arrows) the ISC-valve (or the IAC-valve) to the case заслонки and remove the valve.
3. At valve replacement establish the thermovacuum TVV-valve which has been removed from the replaced ISC-valve, and replace a lining.
4. Installation is carried out upside-down.
