Hi bplboy,

JustAnswer is asking me to answer your question -- " Hi, I have 2005 Nissan Altima 2.5SE. It is CA emission enabled. I just got my check engine light and found that error code is P0420. My mechanic is saying that my car needs O2 sensor and front Catalytic Converter. It would be great if you can tell me how much it should cost and best place to get it done.

Thanks,

Raj
