Fault Code: Cat 1 Bank Failure

[miller]

I was out on the lake tonight putting around for about 45 minutes and I received a fault code message on my screen saying a stored fault "Cat 1 Bank Failure" with a a beeping coming from behind my clear screen. After turning the boat and battery switch off, it went away. Any thoughts on what could have caused this? 2017 RZX3.
Thanks,

O2 sensor. You are likely good. If you get a STFT code or other codes in the SPN 3000 ranges you have an o2 on the port side that is likely the issue.

I've honestly started calling this the EPA/California light. Engine ECM doesn't think you are meeting emissions. Id say keep boating and se eif it stays away..
