What is a shutter grille on a Honda?
Modern vehicles are equipped with a variety of advanced technologies designed to improve performance, fuel efficiency, and aerodynamics. One such feature found in many Honda models is the shutter grille. This article will explain what a shutter grille is, how it works, and why it is beneficial for your vehicle.
Understanding the Shutter Grille
A shutter grille, also known as an active grille shutter, is a system integrated into the front grille of a vehicle. It consists of a series of adjustable slats or shutters that can open and close automatically based on driving conditions. This feature is commonly found in newer Honda models as part of their commitment to improving fuel efficiency and reducing emissions.
How Does a Shutter Grille Work?
The shutter grille operates using sensors and an electronic control system. Here’s how it functions:
- At Low Speeds or Idle: The shutters remain open to allow maximum airflow to the engine and radiator, ensuring proper cooling.
- At Higher Speeds: The shutters close to reduce aerodynamic drag, which improves fuel efficiency and enhances vehicle performance.
- During Engine Warm-Up: The shutters may stay closed to help the engine reach its optimal operating temperature more quickly, reducing emissions and improving efficiency.
The system is designed to balance the need for cooling with the benefits of improved aerodynamics, making it a smart and efficient feature for modern vehicles.
Benefits of a Shutter Grille
The shutter grille offers several advantages for Honda owners:
- Improved Fuel Efficiency: By reducing aerodynamic drag, the shutter grille helps the vehicle consume less fuel, especially during highway driving.
- Enhanced Engine Performance: Proper airflow management ensures the engine operates at its best, whether it’s cooling during heavy use or warming up quickly in cold weather.
- Lower Emissions: Faster engine warm-up times and optimized performance contribute to reduced greenhouse gas emissions.
- Quieter Ride: With the shutters closed, there is less wind noise, leading to a quieter cabin experience.
Maintenance and Troubleshooting
While the shutter grille is a durable and low-maintenance component, it’s important to keep it clean and free of debris to ensure proper operation. If you notice warning lights on your dashboard or experience overheating, it could indicate an issue with the shutter grille system. In such cases, it’s best to have it inspected by a professional mechanic.
Conclusion
The shutter grille is a prime example of how modern automotive technology is enhancing vehicle efficiency and performance. If you own a Honda equipped with this feature, you can enjoy the benefits of improved fuel economy, reduced emissions, and a smoother driving experience.

Frequently Asked Questions
What does a grille shutter do?
Active Grille Shutters are key components for the aerodynamics in the front part of the vehicle, designed to improve fuel efficiency by reducing air drag. At high speeds, the shutters automatically close, redirecting air away from the engine compartment and thus enhancing the vehicle's aerodynamic performance.
Can I drive with an active grille shutter malfunction?
Yes, you can drive with the shutters open. It is a failsafe design so that they won't block airflow through the radiator and cause the engine to overheat.
How to fix grille shutter malfunction?
Clear Blockages: Remove any debris or dirt around the grill shutters that might obstruct them; this should often resolve minor issues. Reset the Code: Once the shutters have been cleaned or inspected, use an OBD-II scanner such as Foxwell GT60 to clear and reset any error codes and the check engine light.
Can I drive with a broken grille?
Driving a car with a cracked grille is very likely to result in further damage to your car. It may also be unsafe and potentially illegal.
How to tell if active grill shutters are working?
Use an OBD-II Scanner: Plugging an OBD2 scanner into your vehicle's diagnostic port can allow you to retrieve error codes. Look for specific codes, such as P05A0 or P059F, indicating active grill shutter issues. Foxwell GT60 OBD-II Diagnostic Tool is an ideal choice for this task.
Can an active grill shutter cause a check engine light?
Yes, malfunctioning active grill shutters can activate the check engine light on any vehicle.
Where is the grill shutter located?
The active grille shutter is located at the front bumper lower opening. This system controls the amount of airflow into the engine compartment via a flap which is operated by an actuator that receives signals from the ECM.
What does the shutter grille problem mean?
The most common issue involves the active grille shutters becoming stuck – either open or closed. This may be due to a failed motor or the mechanical linkage between the motor and shutters has failed. Or, the electrical signal at the motor may be faulty.
What is the Honda Active shutter grille?
Active grille shutters open to allow more air to hit the radiator, otherwise they stay closed to help warm the engine up quicker and allow for better aerodynamics when driving at speed. I also learned when they malfunction it triggers a check engine light because it's considered an emissions-related item.
