Do carburetor cars need oxygen sensor ?

  1. Jun 27, 2015 #1
    Hi all,

    I just hear from a friend that in carburetored cars there are still O2 sensors (not all cars). I not sure the purpose of O2 sensor in this case. Could anyone help ?

    Some carbureted cars had electronically adjustable jets and used an O2 sensor to maintain a stoichiometric fuel/air ratio for the catalytic convertor.

    Thanks insightful.
    I have searched myself and find that some Honda car during the 1980s used programmable carburetor.
