The codes are relating to an O2 sensor issue. Here is a link to the Kohler engine manual website. You will need the section for the EFI Bosch system. It gives the diagnostics codes and troubleshooting charts.


Need to put in the CH26 in the model search field and then scroll down toward the bottom of the page for the service manual.

Check your fuel pressure with a gauge before the fuel rail. I had the same problem. Chased the codes with new O2 sensor and all. It wasnt until I detected low fuel pressure was the culprit.
