Second lamba sensor

  1. #1
    Ive got a Mk2 VTS, i was wondering what would happen if you was to unplug the second lamba completely rather than sleeve it?

    The ECU would see a fault

    As above, your engine management light will come on, but the car won't run any different.

    The light does occasionally come on with the sensor sleeved too. 3 plugs are hit and miss.

    Best to get it sleeved though as u may encounter other problems and wont be able to notice with your light on anyway..
