2002 D2. I just changed bank 1 sensor 1 O2 sensor. That code did not resurface. I also changed plugs during this cycle of maintenance. Getting to that O2 sensor and getting enough force on it to break it out was tough but I did get it with a big 22 mm box end and a 4 pound mallet after two days of soaking. I didn't run the car hot or use a torch just because I would have fried my forearms working around that pipe. Many rust flakes in all head orifices.
The SES light went out immediately on fixing the O2 sensor. 3 days later I got the P1171 and P1174 but the bank 1 sensor 1 did not come back.
Is this an adaptive thing. Did the engine learn to compensate for the discontinuous O2 sensor and so now to I have to somehow reset and start over?
The truck is running PERFECT right now. The plugs were bad and the O2 sensor that I took out was definitely bad.
Should I run a tank through it and drive a bunch of different conditions and then clear codes again?
