The system EVAP



Elements of system EVAP
Fig. 2.354. Elements of system EVAP




Purge solenoid valve
Fig. 2.355. Purge solenoid valve



Check purge solenoid valve
Disconnect the vacuum hose (black with a red stripe) from the solenoid valve.
Disconnect the solenoid valve connector.

NOTE
Canister purge solenoid valve is controlled by an electronic engine control unit; a low coolant temperature and when the engine is idling, the valve is closed, and evaporating the fuel is not fed into the receiver inlet manifold. However, the engine is warm and in the normal driving mode, the valve opens and fuel vapor received into the receiver inlet manifold.

NOTE
When disconnecting the vacuum hose is always pre-coated with the timing marks to when connecting hoses were installed in its original position.


Connect hand vacuum pump
Fig. 2.356. Connect hand vacuum pump


Connect a hand vacuum pump to solenoid valve nipple from which the vacuum hose was disconnected with a red stripe (Fig. 2.356).

Check purge solenoid valve
Fig. 2.357. Check purge solenoid valve


Create a vacuum with a vacuum pump and check valve operation when connecting / disconnecting the power from the battery to the conclusions of the valve (Fig. 2.357).

Current measurement on the findings of the valve
Fig. 2.358. Current measurement on the findings of the valve


Measure the current at the terminals of the solenoid valve (Fig. 2.358).


Test Data
Winding (at 20 ?� C): 0.45 A or less (at 12).
Winding resistance: 26 ohm (at 20 ?� C).

Check the vacuum hose

Vacuum hose
Fig. 2.359. Vacuum hose



The engine coolant temperature: 80-95 ?� C.
Disconnect the vacuum hose from the nozzle of the fuel vapor recovery system on the intake manifold and connect a hand vacuum pump fitting.
Start the engine and check that with the increase in speed of the crankshaft of the engine, the vacuum remains fairly constant.

NOTE
If a vacuum is created, it is likely that there are deposits in the channel nozzle of a vacuum hose (throttle body) and must be cleaned.

Check adsorber
Check the condition of the safety valve of an adsorber (CCV) and the filter as shown in the figure.
Visually check for loose connections, damaged or kinking the hose system EVAP.
Visually check for deformations, cracks or leaks of fuel in the joints.

Adsorber
Fig. 2.360. Adsorber


Remove the adsorber and check for cracks or damage (Fig. 2.360).

Check two-way valve

Check two-way valve
Fig. 2.361. Check two-way valve


Make sure that the air flows through the valve in the direction shown in Figure 2.361.
When installing the valve, make sure it is correctly oriented according to the arrow marked on the valve body.

Check the filler cap of the fuel tank

Cover Gasket
Fig. 2.362. Cover Gasket


Check the condition of the O-ring cover and the fuel filler cap for damage or deformation. If necessary, replace the filler cap (Fig. 2.362).
