This code means there's a problem with the part of the car that opens and closes vents in the front to help control the engine's temperature. It's saying that the temperature signal for this part isn't working right.
The P3064 code indicates that the Powertrain Control Module (PCM) has detected an issue with the temperature signal from the Active Grille Air Shutter Module 'A'.
The Active Grille Air Shutter system is designed to improve aerodynamics and engine efficiency by opening and closing shutters in front of the radiator. The 'A' temperature signal is used by the PCM to determine when to open or close these shutters. An error in this signal can cause the shutters to malfunction, potentially affecting engine cooling and fuel efficiency.

Sensor Issue
• Avoid driving in extreme temperatures until fixed.
• Monitor engine temperature closely.
Check with the vehicle manufacturer for warranty coverage on emissions-related components.
This code has become more common with the increased use of active grille shutters in modern vehicles to improve fuel efficiency.
Moderate – Should be addressed soon to prevent potential engine overheating and ensure optimal fuel efficiency.
Ignoring this issue may lead to engine overheating, which can cause engine damage. Always address engine-related codes promptly.
• Engine running
• Vehicle at operating temperature
The Active Grille Air Shutter is located at the front of the vehicle, near the radiator.
Q: Can I drive with a P3064 code?
A: It's possible to drive, but it's not recommended as it can lead to engine overheating.
Q: How do I reset the P3064 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
