p0420 dtc 2006 matrix
Hello. My ex had a check engine light illuminate. I read the code and it came up p0420, catalytic converter efficiency, bank 1. Is this an o2 sensor? If so, which one? Her car has just over 50k miles on it. Is this still under warranty (80k) for emissions? are there any TSB's out for this problem?
This car has been a lot of trouble since new. I replaced a computer at just over 40k miles, and it had alignment issues after 10k miles. It certainly has tainted my opinion on toyota's.
Anybody with any advice or info, I would much appreciate it. Thanks, Jay
