What does code P02CE mean?

Q: What does code P02CE mean?

Cylinder 2 Fuel Injector A Offset Learning At Min Limit. P02CE indicates that the engine control module has learned a fuel injector offset correction for cylinder 2 that has reached its minimum allowable limit, meaning the injector is flowing more fuel than expected and the computer can no longer lean it out. The code is set when the adaptive learning value for that injector bottoms out during closed-loop fuel control.
