Fault Code P0430

[toyotatoyota]

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.

To help determine if the catalytic converter is bad, this past thread may offer some help. You'll want to use the forum's search feature to locate other threads that may help with your issue.

TrailDust, I did search. I found 4 thread which one of them was my thread about code P1155. The thread that you pointed in my direction ended up with tightening the gas cap and selling the car. Also I don't have an expensive OBDII reader to do all those testing. I have a cheapo harbor freight reader.

Thanks for the link. So i guess from my understanding, my car has 3 cats. 2 on the manifold and one under the car. I haven't check yet but will check it out to see if there's a sensor.
