    Dear friends, I have a Vauxhall Zafira 2001 petrol, and trying to fix some problems. The engine light and service vehicle light occasionally appear on dashboard - specially when driving long distance. OBD 2 reader gives two errors : C3895(00) and U3111(7F) and there is no signal from bank 2 oxygen sensor. I have recently replaced the Oxygen sensor but still no signal appears on my OBD2 app.
    I am trying to understand if there is a relationship between dashboard lights, OBD 2 errors and no signal from lambda sensor.

    Did anybody faced with same issue and how to fix it? Thanks
