P232FO2 Sensor Out of Range During Deceleration Bank 1 Sensor 2

P232F means the powertrain control module (PCM) has detected that the downstream oxygen sensor on bank 1 is reporting a voltage outside its expected range specifically during deceleration. The PCM monitors this sensor's signal when the engine is in closed-loop fuel control and the throttle closes, and it sets the code when the voltage does not behave as the calibration expects for that condition.
