Hi I'm getting a couple of intermittent P Codes.
1 P221401 - 02 sensor signal biased / stuck lean bank 2 sensor 3
2 P221401 NOx sensor circuit range / performance bank 2
I attained these codes using my icarsoft MB V1.0 scanner. I don't know if it's relevant but the codes have only appeared since using E10 fuel that is now used in the UK.
Any thoughts. And could someone direct me as to where these sensors are situated.
