Check Engine Alarm

[Melch66]

Need some help with my 2014 212x check engine light. Starboard engine fault code...."202 52 1103". All I can find is maybe O2 sensor. Maybe. Any suggestions? Can't find any info on it. Boat runs fine, just alarm keeps going off every few minutes.

Can't give any specifics but in the car world the o2 sensor is the oxygen sensor. Not too uncommon to need to be changed. Have you been using any unusual fuel additives? I use Yamaha Ring Free to help reduce carbon build up. Initially you might try a can of Sea Foam. It may help. If not changing the sensor may be your only option.

Thank you. Hope that works. Bought it a few months ago and fuel was from last year. Put 20 gal of fresh in with the 30 gal of old. Been running good. Thanks for the tip.
