EVAP system check
- Examine lines and EVAP system connections, together with a jellied tube and a cover (with laying) a jellied mouth of a fuel tank on existence of damages and weakening of fixture; faulty components replace.
- Warm up the engine to working temperature and muffle it.
- Establish the vacuum gage on the service union of the line of a purge of EVAP system.
- Separate the socket of electroconducting of VSV of EVAP system and submit on the sensor tension of the battery. Start the engine.
- Consider vacuum gage indications – they should keep in a range of 9.35 ÷ 501 mm of mercury. during not less than 5 pages.
- If the vacuum does not change, it is possible to assume existence of leaks in a hose connecting VSV to the service union, or malfunction of VSV.
- Join the VSV socket.
- Give 4 nuts and remove protection of an adsorber.
Press a hose of dumping of air in the specified place and submit to the line pressure of 25.2 ÷29 of mm of mercury. via the service union. In two minutes after pressure giving the vacuum gage should show 14.39 ÷ 16.45 mm of mercury. At unsatisfactory results of checks it is possible to assume existence of leaks through a hose of connection of VSV with an adsorber and with a fuel tank, or zalipany VSV in open situation.
- Make sure of that pressure falls at removal of a cover of a fuel tank. If pressure does not fall, it is possible to assume that the hose connecting the service union to a fuel tank is hammered. Disconnect the vacuum gage from the union.
- Check tightness of a fuel tank and its jellied tube. For this purpose disconnect an EVAP line hose from an adsorber and create in a tank pressure of 0.04 atm. Pressure should not fall within not less than 1 minute. Connect the removed hose.
- Disconnect a hose of the EVAP line and a hose of the line of a purge from an adsorber. Disconnect from an adsorber a hose of descent of air and закупорьте a hose and the union on an adsorber.
- Submit pressure of 0.04 atm to the union of the line of a purge on an adsorber and make sure of that, the EVAP union leaves air. Connect to an adsorber a hose of the EVAP line and a hose of the line of a purge.
- роверьте passableness of a hose of supply of air.
- Remove adsorber assembly. For this purpose:
- Separate the socket of electroconducting of the VSV valve of a purge;
- Disconnect from an adsorber a hose of the line of a purge, a hose of the EVAP line and a hose of the line of supply of air;
- Disconnect from an adsorber a hose of the line of ventilation. For this purpose press it inside, wring out clamps and extend a hose;
- Turn out 3 bolts and remove assembly of a coal adsorber.
- Examine an adsorber on existence of cracks and other damages.
- To Zakuporta the union of ventilation and, having left corked the purge union, submit to the EVAP union air under the pressure of 0.02 atm. Make sure that air leaves the union of dumping of air.
- Having corked unions of a purge and air dumping, submit to the EVAP union air under the pressure of 0.02 atm. Make sure that air leaves the union of supply of air.
- Create vacuum of 25.7 mm of mercury. of the purge union also make sure that the vacuum does not fall down when closing the union of supply of air. At the same time when opening the union of supply of air the vacuum should accrue.
- To Zakuporta the union of supply of air, create in the EVAP union vacuum of 25.7 mm of mercury. also make sure that air arrives in the purge union.
- Check VSV of system EVAP, VSV of the valve of a purge, the VSV valve CCV and the sensor of pressure fuel паров (see. Section of Check of system of injection).
