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 a 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 a chamber of a butterfly valve), the car should be handed over in service of car service, or in a specialized workshop.


Check

Connection of a tachometer to IG conclusion (–) the diagnostic socket


PERFORMANCE ORDER
1. Put the car on the emergency brake, establish a control lever of a check point in neutral provision (manual transmission) or in the 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 nakorotko conclusions of TE1 and E1 of the diagnostic socket.
3. Turns of idling have to 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 stated 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.

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

7. Connect the disconnected socket to the valve.

Replacement

PERFORMANCE ORDER
1. Remove a chamber 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 a chamber of a butterfly valve.


2. Unscrew screws and remove the valve with laying.
3. The valve is installed upside-down. Before assembly replace laying of the valve.

DISTRIBUTOR OF FUEL AND NOZZLE

2. Disconnect the battery from weight.
3. Disconnect a hose of system of ventilation of a case from a head of cylinders and the soaking-up collector.
4. On engines 1,6 and 1,8 of l uncover the soaking-up collector (see below items 1-10).
5. Apply accurately distinguishable tags on each socket of a nozzle. Disconnect sockets from nozzles and take conducting aside. On engines of 1,3 l turn off a bolt and disconnect conducting from a mixer rack. Turn off a nut and a bolt and remove a rack.
6. Disconnect a probe vacuum hose from the fuel distributor.
7. Disconnect fuel hoses from the regulator of pressure and the distributor.
8. Turn off bolts of fastening of the distributor of fuel (are specified by shooters).

12. Nozzles are established upside-down.
13. Tighten bolts of fastening of the distributor of fuel with the moment specified in subsection 5.1.

THE VALVE OF COMPENSATION OF TURNS OF IDLING AT TURNING ON OF THE CONDITIONER

Check
PERFORMANCE ORDER
1. Put the car on the emergency brake, establish a control lever of a check point in neutral provision (manual transmission) or in the 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 before establishment of normal working temperature and turns of idling. Turn on the conditioner.
2. A crossing point close nakorotko conclusions of TE1 and E1 of the diagnostic socket.
3. Turns of idling have to increase from 1000 rpm to 1200 rpm within 3 seconds after a peremykaniye of conclusions, and then decrease to the initial. 15 seconds later again check idling turns, the number of turns has to exceed approximately on 100 rpm normal value. If turns of idling change as is described above, the valve is serviceable. If turns increase more than by 100 rpm, adjust the range of turns of idling, rotating the adjusting screw. If turns of the engine do not change or decrease, 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 in norm, the valve is serviceable and it is necessary to check conducting or the control unit. If resistance differs from standard, replace the valve (see below).
7. Give on conclusions tension from the battery and be convinced that air passes from the channel E in the channel F.

Prevention
