Fault Code P0430
So a while back I post a thread about a P1155 which is now fixed. But after 3,000 miles of driving, I now have a fault Code P0430 "Catalyst System Efficiency Below Threshold Bank 2. Also the VSC and TRAF OFF light is on again. I search and only found 4 threads about this code and which they didn't do any follow up.
So it's a 02 Camry V6 XLE with now 138,000 miles. I had replace 3 oxygen/AF sensor so far with all Denso parts. With the earlier code P1155 I end up replacing Bank 1 sensor 2 and Bank 2 sensor 1. Now with this new code P0430, I had replaced Bank 2 sensor 2. Which only leave me with one sensor left to replace. After changing the Bank 2 sensor 2, I used my OBDII scanner to turn off the check engine light. The light stayed off but my VSC and TRAC OFF light is still on. Which indicate that there is still a problem. I checked again but it's showing that MIF light is off.
Could the cat in front be bad??
Do these car have 2 cats that are bolted on to the exhaust manifold or is there more than 2?
Help Please!!! I have to go out of town for a funeral in 2 weeks. Will this cause any damages to the car? It's about 6 hour trip.
