A couple of weeks ago my check engine light came on. I checked the code and it was P0155 02 sensor bank 2 sensor 1. I did a google search and noticed a ton of threads on TS. So I joined TS and found tons of info. I was able to take the info from TS and get 2 02 sensors replaced for free at my dealership. Thank you all for the 02 sensor info and recommendations. You all rock!
