Q: Have a Kohler 5kw marine generator with only 135 hours, its in a 2006 Searay, assuming it is a 2006 as well, I have a code of CO6, which i research to be a bad CO sensor, is that correct and is this the proper replacement sensor for that issue / model? Single Phase 25C 5kw, serial number #######, SPEC; GM39685-GA1
That is a 5ECD and GM46362 is correct.
CO6: Fault code is displayed if the CO sensor is inoperative.
This is normally just a sensor replacement. The sensor should be replaces every 2 years per the maintenance schedule.
