    O2 sensor fault.... even with new sensor

    Any one any ideas on this

    Engine check light comes on , generally provocted by wide throttle on lower revs

    Car seems to run fine,

    Did a decat , problem same

    Has new exhaust made and fitted a new Honda 02 sensor

    Problem still the same

    Capacitors in ECU also replaced

    OK, I think that several issues might cause the engine check light to come on.

    First things first, what makes you think it is the O2 sensor?

    Secondly, does it seem to have any noticeable impact upon performance?
