It is advisable to remove and clean the throttle assembly after 15,000 km of the car’s run, or when malfunctions are detected
Main malfunctions of the throttle assembly:
- - incorrect definition of the extreme positions of the damper;
- - incorrect programming of the damper initial position;
- - damper actuator malfunction (jamming);
- - discrepancy between the set and current damper positions;
- - inconsistency between the set and current damper positions after the latter rebounds from the lower limiter (causes a transition to the backup mode)
