Check Engine Light-O2 Sensors not bad…?
I have a 2012 XLT. Yesterday the Check Engine light came on. Codes were O2 sensors. Bank 1 Sensors 1 & 2. Went and bought new ones, replaced them…easy. Well, not so easy. Seems other have had similar issues. The forum said look for Plug C146-It's the green wire that is corroded. No such plug...- Brucell
