Checking the technical condition
1. Turn off the ignition.
2. Disconnect the air control valve connector.
3. Check if the air supply control valve is clogged with foreign materials.
4. Measure the resistance between the (+) and (-) motor control terminals.
5. Check that the resistance matches the specification.
6. Measure the resistance between the power and ground terminals of the sensor.
7. Check that the resistance matches the specification.
Removal
1. Turn the ignition key to the "OFF" position and disconnect the negative (-) cable from the battery.
2. Disconnect the air supply control valve connector (A).
3. Remove the clamp from the air supply control valve, then disconnect the air intake hose (B).

Installation
Attention.
- Tighten the component mounting bolts to the specified torque.
- Be careful not to drop the component. If dropped, the component must be carefully checked before installation.
Installation is performed in the reverse order of removal.
Note: Tightening torque: Air supply control valve mounting bolt: 8.8 - 10.8 Nm.
Replacement
After replacing the air supply control valve, perform the "Component Change Routine" procedure. Otherwise, a malfunction related to engine performance or exhaust control may occur and persist until data about the new component is registered in the engine control unit.
1. Turn off the ignition.
2. Connect the GDS scanner to the data link connector (DLC).
3. Turn on the ignition.
4. Select "Vehicle, Model year, Engine, System".
5. Select Vehicle S/W Management (Vehicle Software Management).
6. Select Component Change Routine.
7. Select "Air Control Valve (ACV) Change".
8. Follow the procedure according to the instructions on the screen.
