What Causes Your Active Grille Shutter Check Engine Light to Come On?

The active grille shutter check engine light indicates a malfunction with the active grille shutter system which should be checked and serviced as soon as possible.

Active Grille Shutter Check Engine Light

The Active Grille Shutter (AGS) on modern vehicles is an important part of the vehicles overall aerodynamic profile. It is designed to reduce drag by actively controlling the front grille opening to allow for maximum airflow when needed and to close the grille for improved aerodynamics. But if the AGS fails, this could trigger a check engine light on your dashboard, and mean your vehicle needs either repair or replacement.

This overview provides an explanation of how AGS works, what the check engine light means, and the potential solutions available if you encounter a failure of this system.

AGS typically uses an electric motor that operates a series of shutters which open and close depending on engine demand or driver inputs such as road speed. This allows air flow through the grille when required whilst still helping maintain efficient fuel economy.

It is important to note that a check engine light in regards to AGS is not necessarily indicative of a serious issue. Commonly it may indicate that one or more shutter blades are stuck, preventing them from operating correctly, or in some cases can indicate low-level electrical issues with the motor itself.

In order to diagnose what are causing any issues with AGS, fault information will be relayed through a data transfer protocol in order to access deeper details about its operation. In some cases diagnosis will be as simple as removing debris from shutter blades and lubricating components where appropriate but in more complex cases repair parts may need replacing entirely as part of a full system overhaul.

If you experience an active grille shutter warning light at any time it is important to take it seriously in order minimize any further damage that might be caused by allowing it continue operating unpredictably. Regular checks also should also be undertaken using applicable factory diagnostics tools in order to ensure continued proper operation of this system – especially when surveying pre-owned vehicles before purchase.
