- remove the top part of the air filter 1 (see fig. 202 );
- disconnect a shtekerny block of the 5th sensor of a mass consumption of air and a shtekerny block 7 heating elements;
- remove from a head of the block of cylinders the valve 10 of system of ventilation of a case and the ventilating hose 11 going to the electromagnetic valve 13 of system of cleaning with application of absorbent carbon from the top part of an inlet collector;
- disconnect wires of a high voltage (VN) from spark plugs (the special tool of 3 277 A for this purpose is required);

Fig. 201. The top and bottom parts of an inlet collector and the details located nearby: 1 — the top part of an inlet collector; 2 — VN directing wires; 3 — a sealing ring; 4 — a hose of supply of fuel; 5 — a hose of return of fuel; 6 — the fuel distributive highway; 7 — a bolt, 10 N · m; 8 — the lower part of an inlet collector; 9 — laying, replace; 10 — a nozzle; 11 — an O-shaped sealing ring; 12 — a bolt, 25 N · m; 13 — an elevating eye; 14 — an arm of the valve of supply of secondary air; 15 — the valve of supply of secondary air; 16 — a vacuum hose; 17 — a shtekerny block, dark blue color; 18 — collars; 19 — a regulator of pressure of supply of fuel; 20 — a shtekerny block, black color; 21 — the directing plug; 22 — a shtekerny block, black color; 23 — the temperature sensor; 24 — T-shaped;;;;;;; 25 — a vacuum hose, to the amplifier of a brake drive





- remove VN 2 directing wires (see fig. 201 ) from a lobby and the opposite side of an inlet collector 1;

Fig. 200. The details established near the case of a butterfly valve: 1 — the top part of an inlet collector; 2 — directing a cable; 3 — a bolt, 10 N · m; 4 — a back right support between the top part of the inlet pipeline and a head of the block of cylinders; 5 — a bolt, 25 N · m; 6 — a vacuum hose, from the valve of system of ventilation of a case; 7 — a ventilating hose, from cleaning system by means of absorbent carbon; 8 — T-shaped;;;;;;; 9 — the butterfly valve case; 10 — a shtekerny block, black color, 8 sockets; 11 — laying, it is necessary to replace; 12 — a support of a cable of a drive of a butterfly valve; 13 — a connecting element, 35 N · m (for the EGR valve); 14 — a "mass" cable; 15 — the left back support between the top part of an inlet collector and a head of the block of cylinders





- remove a cable of a drive of a butterfly valve together with a support 12 (see fig. 200 ) a butterfly valve drive, but make it so that not to delete a collar of fastening of a cable;
- mark and remove hoses of cooling liquid from the butterfly valve case. Thus the system of cooling should not be under pressure;
- disconnect топливопроводы from a head of the block of cylinders;
- for some time open a cover of a fuel tank (to lower excessive pressure) then impose places of accession of hoses with a thick rag and slowly disconnect hoses. If fuel after all scatters, he will be detained by a rag;

Fig. 203. Detachment of a vacuum hose of the inlet valve of secondary air





- disconnect a vacuum hose ( fig. 203 , it is shown by an arrow) inlet valve of secondary air between a regulator of pressure of supply of fuel and the top part of an inlet collector;
- disconnect the vacuum hose going to the amplifier of a brake drive;
- unscrew both back arms between the top part of an inlet collector and a head of the block of cylinders;
- unscrew an EGR valve hose on the top part of an inlet collector;
- unscrew directing tube maslomerny щупа from the lower part of an inlet collector;
- remove the top part of an inlet collector together with the butterfly valve case (at installation pay attention to an arrangement of directing plugs) and at once закупорьте open inlet channels;
- disconnect electric wires from nozzles, from the switch of pressure of oil and from the sensor of temperature of oil;
- remove nozzles together with the distributive fuel highway;
- remove clamps of nozzles and nozzles. If the nozzle sits very strong on the place, under its case it is possible to substitute a rozhkovy wrench on 16 mm and with its help to squeeze out a nozzle
- remove About-shaped rings from both ends of a nozzle and at once them throw out.

Cause of defect
Elimination method

The cold engine is not started or started with great difficulty
1. The fused safety locks No. 15 and No. 18
1. To replace

2. The relay which is responsible for tension is faulty
2. To check on HUNDRED

3. The fuel pump (in the engine the insufficient amount of fuel arrives) is faulty
3. The pump repair or replace on new (repair will need a special key)

4. The regulator of pressure of fuel is faulty
4. Inspect a regulator of pressure upon HUNDRED

5. The sensor of temperature of cooling liquid is faulty
5. Check, by means of an ohmmeter, the temperature sensor

6. The butterfly valve drive is faulty
6. Inspect on HUNDRED

7. EBU is faulty
7. Carry out its check on HUNDRED

8. Wires between the Hall and EBU sensor are interrupted
8. Check and repair

9. The engine soaks up air through not tight places of connections or the damaged hoses
9. Check all connections of hoses located on the case of the air filter or leaders to it

The heated-up engine is not started or started with great difficulty
1. The vacuum pipeline conducting to a regulator of pressure of supply of fuel is not tight
1. Check. Carry out all specified checks

2. Nozzles are not tight
2. Check them on HUNDRED

The engine is started, and then again глохнет
1. The butterfly valve drive is faulty
1. Inspect on HUNDRED

2. The vacuum pipeline conducting to a regulator of pressure of supply of fuel is not tight
2. Check

3. It is faulty a lambda probe
3. Inspect on HUNDRED

The engine strongly vibrates idling
1. The relay of supply by tension or the sensor of temperature of cooling liquid is faulty
1. Check independently or on HUNDRED

Engine глохнет
1. The fuel filter is hammered
1. Establish the new filter

2. The fuel pump (in the engine the insufficient amount of fuel arrives) is faulty
2. The pump repair or replace on new (repair will need a special key)

3. Nozzles are not tight
3. Check them on HUNDRED

4. The butterfly valve drive is faulty
4. Inspect on HUNDRED


Prevention
At removal of nozzles be careful not to damage tips of the socket and sprays. Nozzles do not understand.

Prevention
Hit of engine oil in a nozzle is not allowed.

Installation of nozzles carry out as it should be, the return to removal. Grease new About-shaped rings with pure engine oil.
