Q: What does code P232B mean?

Cylinder 11 Fuel Injector A Offset Learning At Min Limit. P232B indicates that the powertrain control module (PCM) has learned a fuel injector offset correction for cylinder 11 that has reached its minimum allowable limit, meaning the injector is flowing more fuel than expected or the circuit is behaving outside the normal adaptive range. The PCM monitors injector performance during closed-loop operation and stores this code when the learned offset cannot be adjusted any further downward to maintain proper air-fuel ratio.
