[QUOTE="ionbeam, post: 489099, member: 277"] A few Gen I's set an O2 code. A number of '03 Gen I's will set an O2 code even when the sensor is plugged in, the trigger seemed to be moisture. Some Gen I's will set an O2 code when a PCIII is used and the O2 sensor is disconnected. In all cases the 'cure' is to just reset the code in the ECU and get on with life. A very few are plagued with the error code and just live with the light, I believe one of Skoot's FJRs has this issue which got worse as the bike aged. Just an observation with no facts to back it up -- it seems that an open O2 sensor does not set a code but when moisture gets into the sensor wires and alters voltages out of a range which the ECU expects it will set a code. The moisture could be wash, rain or even condensation as temps rapidly change, such as when I pull my cold FJR out of my garage into 70 degree air or climb Mt. Washington where it can be 80 degrees at the bottom and 6 miles later it is 20 degrees. Reset & forget. [/QUOTE]
