Is there any diagram or image showing the location of the O2 sensor? I couldn't find anything in the owner's manual, and I haven't been able to find any videos for my exact ATV model.
And another question: since the ATV still runs with the EFI light on, is it safe to keep using it? I'm asking because it's my only means of transportation where I live.
Thanks again, I really appreciate your help.

Hi everyone,
We live on an island, and at this time of the year we have a lot of mud. After I washed the wheels with water, the EFI light remained on.
Could anyone share a link to a video showing how to test the O2 sensor myself?
Thanks in advance!

Hi, I have a CForce 400 AU-L model, and yesterday the display showed the error code P013000 with the EFI warning light on. After a while, the error code disappeared, but the EFI light stayed on. Today, the EFI light is still on, although I can ride the ATV without any problems. Does it need any maintenance, or does anyone know what could be causing this? Any help would be appreciated.
