What happens when the O2 sensor is too lean?

The ECM/PCM and the O2 sensor are all about keeping things balanced in the combustion chamber. If the mixture drifts too far out of balance, a rich or lean code is stored and ECM/PCM’s fuel trim strategy alters injector pulse width, moving the mix in the opposite direction of the condition to bring the air/fuel mix back into balance.
