Check engine light

[oommenthomas92]

Hey there so I did an upgrade on my filter and upgrade my exhaust too and after doing that all I have a check engine light pop up and all other codes are coming up. Do y’all know how can I fix this on a vitpilen 701

Your going to have to read the codes to get a direction, I would double check you plugged all the sensors and connectors back in.

I can see your missing the cable for the o2 sensor in the exhaust header pipe. Have you removed it and not plugged anything into the cable that remains?
