P2EAAActive Radiator Air Flow Control Module A Control Circuit Performance

P2EAA indicates that the powertrain control module has detected a performance fault in the control circuit for the active radiator air flow control module, which is the actuator that opens and closes grille shutters or an air dam to manage cooling airflow. The computer monitors the circuit for expected electrical behavior and sets this code when the circuit does not respond as commanded, often due to an open, short, or mechanical binding.
