Q: What does code P2B02 mean?

Cylinder 3 Injection Pulse Performance. P2B02 indicates that the powertrain control module (PCM) has detected an abnormal injector pulse performance for cylinder 3, meaning the electrical signal sent to the fuel injector did not produce the expected current or voltage response. The PCM monitors the injector circuit for opens, shorts, or excessive resistance and sets this code when the pulse width or current draw falls outside the expected range for the commanded injection event.
