So I have a P0135 O2 Sensor question. I got this code and it's saying that the heater for the o2 sensor is bad. The CEL comes on and off randomly. It is for Sensor 1 Bank 1. Which one is that and how important is that for me to get changed right away? Thanks!

Anyone???

I did some searching for this code and there are no posts on it. Someone has to know.

I just had it with my S. I didn't have the time to do it nor did I want to do it, it is in a PITA location. I just payed to have a shop do it and it was all good.
