Checking the purge valve
1. Prepare the vehicle for operations (see "Preparing a car for maintenance and repair").
2. Having released the retainer, we disconnect the wiring harness block from the adsorber purge valve.
3. Connect the "negative" probe of the voltmeter to the "mass" (car body).
4. Turn on the ignition and use a voltmeter to measure the supply voltage at terminal "A" of the wiring harness connector (terminal designations are made on the block).
The voltage at the terminal must be at least 12 V. If the voltage does not reach the connector or is less than 12 V, the battery is discharged, the power supply circuit is faulty, or the ECU is faulty.
5. To check the valve itself, use a Phillips screwdriver to loosen the clamp securing the hose to the purge valve of the adsorber and remove the hose.
If the hose is tightly seated on the branch pipe and it is not possible to disconnect it, you can remove the valve from the adsorber and, by rotating the valve, remove the hose from it.
6. Using a screwdriver, remove the valve from the adsorber (for clarity, shown on a removed adsorber).
7. Apply 12 V voltage from the battery to the valve terminals ("+" to terminal "A", "-" to terminal "B").
When voltage is applied to the terminals, the valve should open with a characteristic click. Otherwise, the valve is faulty and must be replaced.
Removal the adsorber
1. Disconnect the wiring harness connector from the purge valve of the adsorber and remove the hose from the branch pipe (see above).
2. Using a Phillips screwdriver, loosen the clamp securing the fuel vapor supply hose to the adsorber and remove the hose.
3. With a socket wrench by 10 mm we unscrew the clamp bolt of the adsorber mounting clamp.
4. Remove the adsorber.

Installation
The installation of the adsorber is carried out in the reverse order.
