Yale Error codes 522637.3 and 522633.2

The forklift is showing both codes but still running and functional. Just wondering what these indicate and whether serious or livable. Thanks.

First code is pre-cat bank2 short term fuel rail lean. second code is pre-cat bank2 fails to switch rich. Sounds like a pre-cat O2 sensor problem.
