Hi..

I have a 1998 honda accord V6. I got the Check engine light today,
using an OBD scanner i found out the code was "P0420 - Catalytic
emission low on Bank #1". The local repair shop tell me that i need to
get the Catalytic convertor and the 02 sensors replaced.

I have the following questions for the group.
1. Does the code P0420 mean that the catalytic convertor is bad?
2. He quoted the cost for a replacement Catalytic convertor for $550
and O2 sensor for $138.. do these seem high?

Just a few days back i had replaced the alternator in this car .. FYI..

Thanks,
Ritesh
