330i pre-cat o2 sensor problem
Hi Everyone!
Recently I replaced my 2 pre-cat o2 sensors, due to some codes on bank 1. After replace everything seemed to be fine, shaking at idle dissapeared, car runs fine. But during the test drive with INPA connected, I received new error on bank 2 - see picture below: https://zapodaj.net/457a3757c0b40.jpg.html I have noticed that error occurs when I release acc. pedal for few seconds. The bank 2 sensor goes to over 4V and hangs up on 2,8V and doesn't move anymore. After error erase, sensor operating normal, until next gas pedal release for few sec., and so on. It is visible at 1:12 of my movie: If You have any suggestions, I will appreciate. Thx! |
