The two codes I had were:
2d0d - oxygen sensor before cat heating
2cff - oxygen sensor before cat
I have not had any 2d0d codes after the replacment o2 sensor, but I don't know if it's because they replaced the sensor or because I fixed the chargepipe leak at roughly the same time.
I HAVE had 2cff come back though, which is very frustrating and also related to o2 sensors.
I am suspecting that misfiring caused by e85 mixture problems is killing the o2 sensors due to heat, especially because the 2d0d code is specifically for heating.
