p0420

  1. 3G (2006-2014) Vitara & Grand Vitara
    Newbie here, only had the 07 V6, auto, 5 dr prestige 4 month's and according to the scanner it shows that code P0420 is the cause of it. Now I have read nearly everything about it on this forum and was wondering if there was anything new to rectify and or properly diagnose the the exact cause...
