At just over 295,000 miles and today my Check Emission Light appears.Both o2 sensors are fairly new. Pull the code and P0420. So I go to Honda and there is a rattling sound. So I am getting myself a new converter for Xmas. The price is high but considering the mileage I am not too hurt. To add insult to injury the A1245 all appeared too so I have 80 percent oil life and will be back for all these services too. Will also have the cvt fluid swapped out also. I kinda wish I had bought all the performance parts instead but I think I would have had to buy a Hondata and a laptop,I own neither and too to keep CEL from coming on. I've convinced myself to only modify before a sensor going up and after going down just yo be safe.
