PGM-FI light flashing

I have a 2014 Honda 420 that has an engine light flashing. 2 long flashes and 3 short flashes. Any ideas

I would have to look at the manual but I think that is the O2 sensor code.

How can i research those codes in the manual? Is there a service manual? Or should I just start with the O2 sensor and go from there?

You need a service manual to get the code list. 23 is for the O2 sensor heater malfunction. Check the connector for moisture or loose connection.
