DIAPHRAGM OF THE AIR VALVE OF SYSTEM OF ADJUSTMENT OF SUPPLY OF AIR (ONLY MODELS WITH THE ENGINE IN VOLUME OF 1,8 L)
Check
PERFORMANCE ORDER |
|
1. Check a course of a rod of a diaphragm. It should rise smoothly and опускться. |
|
2. Check receipt of depression on a diaphragm and diaphragm work. |

SENSOR OF PROVISION OF THE BUTTERFLY VALVE
Arrangement of plugs of the sensor of provision of a butterfly valve on models after 1995 of release
|
On models of 1990-1994 of release between the bottom plugs of the sensor there should not be a conductivity. |
Check
PERFORMANCE ORDER |
|
1. Insert щуп in the thickness: а) On models of 1990-1994 of release with an automatic transmission – 0,6 mm; б) On models of 1990-1994 of release with a mechanical transmission – 1,0 mm; в) On models after 1995 of release – 1,3 mm between the lock screw and the lock lever of a butterfly valve (it is specified by an arrow). |
2. Check, that between plugs of the sensor there was no conductivity. |
|
Adjustment
PERFORMANCE ORDER |
1. Connect an ohmmeter to the bottom plugs of the sensor of provision of a butterfly valve. |
|
2. Turn off two fixing screws of the sensor (are specified by shooters). |
3. Insert щуп the specified thickness between the lock screw and the lock lever: а) On models of 1990-1994 of release with an automatic transmission – 0,25 mm; б) On models of 1990-1994 of release with a mechanical transmission – 0,4 mm; в) On models after 1995 of release – 0,15 mm. |
4. Turn the sensor clockwise on 30 °, then turn it back so that there was a conductivity. |
5. Insert щуп the specified thickness and check, that conductivity was not: а) On models of 1990-1994 of release with an automatic transmission – 0,4 mm; б) On models of 1990-1994 of release with a mechanical transmission – 0,7 mm; в) On models after 1995 of release – 0,5 mm. |
6. If conductivity is present, repeatedly adjust the sensor. |
7. Tighten two fixing screws. |
8. If the sensor does not give in to adjustment, replace it. |
|
Replacement
PERFORMANCE ORDER |
1. Disconnect the connection socket, turn off fixing screws and replace the sensor. |
2. Adjust the new sensor. |
|
REGULATOR OF PRESSURE OF FUEL
