Active Grille Shutter Position Sensor Circuit

Diagnostic & Technical Explanation
Code P059A (Active Grille Air Shutter A Position Sensor Circuit) sets when the ECM sees an open, shorted, or implausible signal from the position feedback sensor on an active grille air shutter (AGS) panel, which closes at speed for aerodynamics/warm-up and opens for cooling airflow. Causes are a failed potentiometer/Hall sensor in the shutter actuator, ice or debris jamming the shutter and straining the sensor linkage, or a corroded connector at the front-of-vehicle mounting location.

These 12 diagnostic trouble codes share one detection mechanism and one repair path, which is why MechanicDB groups them into a single authored fault family rather than repeating the same explanation 12 times.
