    Q:
    Why is the oxygen sensor important for the PCM for the 2007 Mercury Mariner? Posted by Customer
    A:
    Without the oxygen sensor, the PCM would be unable to correct the injector on-time, which determines the air/fuel ratio needed to maintain the "perfect" (stoichiometric) air/fuel ratio of 14.7:1 that the catalyst requires for optimal operation.
