2. Disconnect the air control valve connector.
3. Check if the air control valve is clogged with foreign material.
4. Measure the resistance between (+) And (-) motor control outputs.
5. Check that the resistance is within specification.
6. Measure the resistance between the power and «masses» sensor.
7. Check that the resistance is within specification.
Withdrawal
1. Turn the ignition key to position «OFF» and disconnect the negative (-) battery wire.
2. Disconnect the connector (A) air control valve.
3. Remove the clamp from the air control valve, then disconnect the hose (IN) air intake.

- Be careful not to drop the component. In the event of a drop, the component must be carefully checked before installation.
Installation is carried out in the reverse order of removal.
Note: Tightening torque: Air control valve bolt: 8.8 - 10.8 Nm.
Replacement
After replacing the air control valve, follow the procedure «Component Change Routine» (Component replacement program). Otherwise, a malfunction related to engine performance or exhaust control may occur and remain until the data on the new component is registered in the engine control unit.
1. Turn off the ignition.
2. Connect the diagnostic system scanner (GDS) to the diagnostic socket (DLC).
3. Turn on the ignition.
4. Select «Vehicle, Model year, Engine, System» (car, model year, engine, system).
5. Select «Vehicle S/W Management» (Vehicle software control).
6. Select «Component Change Routine» (Component replacement program).
7. Select «Air Control Valve (ACV) Change» (Air control valve replacement).
8. Follow the procedure as instructed on the screen.
