Withdrawal
Remove the air filter.
Disconnect the air damper servo connector.
Remove the air damper servo by unscrewing the four screws securing its flange.
Checking the technical condition
Make sure the choke lever rotates 360°.
Check the mobility of the air damper.
Connect tester (in ohmmeter mode) to the terminals of the air damper servo and check the resistance of the armature winding of the executive motor, which should be in the range of 0.87-1.63 ohms.
Connect a tester between one of the servo pins and the servo case and check the insulation resistance, which should be R=∞.
Note. Checking the resistance of the armature winding of the servo actuator and the insulation resistance can be carried out directly on the vehicle. In this case, the resistance of the armature winding should be in the range of 0.9-1.7 ohms.
Installation
Make sure the tie rod and choke lever are in the correct position.
Install the air damper servo (it can only take one position) and tighten the screws securing the servo flange.
Connect the air damper servo connector.
Install the air filter.
