P05B0 indicates that the active grille air shutter (AGAS) control module has detected that the shutter for bank B has failed to reach or correctly report its minimum or maximum mechanical stop position. The computer compares the shutter position sensor signal against expected values at the fully open and fully closed limits, and sets this code when the sensor reading is out of range or inconsistent with the commanded stop.
