DTC codes / P23xx · Ignition system and misfire / P232F
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.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
