Check and replacement of elements
THROTTLE BODY
Check
| PERFORMANCE ORDER | |
| 1. Check the operation of the connecting mechanism throttle. Check that the throttle is fully opened. | | 2. Inspect the throttle body for wear or deposits. |
|
Replacement
| PERFORMANCE ORDER | | 1. Remove the air supply pipe. Disconnect the accelerator cable. | | 2. Mark and disconnect all vacuum hoses. |  | 3. Disconnect connecting the throttle position sensor. |  | 4. Remove the four mounting screws and remove the throttle body and gasket. | | 5. Clean the throttle body, and blow all channels. | | 6. Installation is spent upside-down removals. Tighten the mounting bolts to the required torque. |

IRIS AIR VALVE adjusting the air supply (only models with an engine capacity of 1.8 L)
Check
| PERFORMANCE ORDER |  | 1. Check the stroke of the diaphragm. It should gradually rise and opusktsya. |  | 2. Check the flow of vacuum on the diaphragm and the diaphragm work. |
|
THROTTLE POSITION SENSOR
Terminal locations throttle position sensor on the models after 1995 of release
| On models 1990-1994 of release between the lower terminal of the sensor should not be conductivity. |
Check
| PERFORMANCE ORDER |  | 1. Insert the probe thickness:
a) On models 1990-1994 of release with an automatic transmission - 0.6 mm;
b) On models 1990-1994 of release with a manual gearbox - 1.0 mm;
c) On models after 1995 of release - 1.3 mm
between the locking screw and locking the throttle lever (arrow). | | 2. Check that the sensor between terminals had no conductivity. |
|
Adjustment
| PERFORMANCE ORDER | | 1. Connect ohmmeter to terminals lower the throttle position sensor. |  | 2. Unscrew the two screws of the sensor (indicated by arrows). | 3. Insert the probe to a specified thickness between the locking screw and locking lever:
a) On models 1990-1994 of release with an automatic transmission - 0.25 mm;
b) On models 1990-1994 of release with a manual gearbox - 0.4 mm;
c) On models after 1995 of release - 0.15 mm. | | 4. Turn the sensor clockwise by 30 ?�, and then turn it back so that the conductivity appeared. | 5. Insert the dipstick and check the specified thickness to the conductivity was not:
a) On models 1990-1994 of release with an automatic transmission - 0.4 mm;
b) On models 1990-1994 of release with a manual gearbox - 0.7 mm;
c) On models since 1995 year - 0.5 mm. | | 6. If the conductivity is present, re-adjust the sensor. | | 7. Tighten the two mounting screws. | | 8. If the sensor can not be adjusted, replace it. |
|
Replacement
| PERFORMANCE ORDER | | 1. Disconnect a connection socket, turn off fixing screws and replace the sensor. | | 2. Adjust the new sensor. |
|
Fuel Pressure Regulator
Check
See subsection 5.2.4.
Replacement
| PERFORMANCE ORDER | | 1. Disconnect the hose from the regulator. |  | 2. Turn off fixing bolts and remove the regulator from the fuel reservoir. | | 3. At installation use a new sealing ring. |  | 4. Install the fuel pressure regulator:
and - control dvleniya
b - fuel tube
1. Properly
2. Wrong
3. Wrong |
|
Control valve supplying air to the idling mode
A warning  To adjust the idle speed is necessary to address to experts.
Check
| PERFORMANCE ORDER | | 1. Check that the engine speed has increased to about 1200 rev / min when disconnecting the valve. If the speed does not increase, replace the valve. |  | 2. Disconnect the connection of the valve and measure the resistance between the terminals of the valve. |
|
Replacement
| PERFORMANCE ORDER | | 1. Remove the throttle body. |  | 2. Turn off fixing screws and remove the valve and gasket. | | 3. Installation is spent upside-down removals. Use a new gasket. |
|
Fuel manifold and injectors
Check
See subsection 5.2.11.
Replacement
| PERFORMANCE ORDER | | 1. Disconnect hoses from the crankcase ventilation system of the cylinder head and intake manifold. |  | 2. Loosen the hose clamps and disconnect the hoses. |  | 3. Unscrew the fixing screws of the air valve (indicated by arrows). |  | 4. Remove the air valve. |  | 5. Mark injectors and connection sockets. Release clips harness injectors. |  | 6. Disconnect the connection injectors. | | 7. Disconnect the hose from the pressure regulator and the fuel manifold. |  | 8. Turn off fixing bolts (are specified by arrows), fastening the fuel manifold to the intake manifold. |  | 9. Remove the fuel manifold with aavtomobilya. |  | 10. Number the injectors. |  | 11. Remove the injectors. |  | 12. Remove the O-ring. |  | 13. Remove the plug on top of the injector. |  | 14. Remove the insulators from the hole in the intake manifold. | | 15. Installation is spent upside-down removals. |
|
COVER AIR SUPPLY
Withdrawal
| PERFORMANCE ORDER | | 1. Mark and disconnect all vacuum hoses. | | 2. Remove the throttle body. |  | 3. Turn off the top fixing bolts / nuts (indicated by arrows). |  | 4. Turn off the bottom fixing bolt (arrow). | | 5. Remove the cover. |
|
Setting
Installation is spent upside-down removals.
