So I bought a 2006 4runner about a month ago. Seemed like every little detail of it was perfect. It was clearly taken very good care of. I took it to get inspected the other day and the garage found that my CEL and vsc trac light do not work. So they pulled the codes and said I need two new cats. Can anyone tell me where to start with o2 sensors or anything before I spend 1500 replacing the cats. Also I checked all of the wiring and all of the fuses and can't figure out why my CEL isn't seemingly getting any power along with the vsc trac light.
