What does P2B02 mean?
The ECM detects that the injection pulse on cylinder 3 does not produce the expected combustion result. Pulse width, timing, or quantity drift compared to the bank average.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Injector aged - flow characteristic drifted
- Medium Fuel quality affecting injection result
