No, they are typically un-related except in the rare case of a bad ECM. As far as it working, im guessing somehow u got an air/fuel sensor from them.. im really not sure. Doesnt really make much sense imo. Im basing the car being cali spec on the code you got, per my lexus TIS information it will only throw a p1155 on a cali spec with a bad AF sensor.. ill try and post up the PDF file on the code tomorrow.

tomorrow at work ill check out your other code to see what its about, i havent personally seen it before so im curious also. theres a few parts that you should never use an aftermarket generic part on, o2 and air/fuel sensors being one of them lol.
