    I am in the process of freshening up my 2003 Tacoma PreRunner 2.7L.

    My next task is replacing the O2 sensor(s) and I need to know what parts I need...

    So far I have ordered a Denso #
    $61 234-4189 Oxygen Sensor
    234-4189 and I need to know if I have to order one more of the same part. Or do I need the A/F Ratio sensor (Denso #
    $137 234-9001 Upstream Air Fuel Ratio Oxygen Sensor with 10.6” 4-Wire Harness, for Auto Trans Equipped Vehicles
    234-9001)?

    Forgive me, I am new. I searched every thread before posting though.

    I do believe that's what you need, but don't quote me on that.

    I had to buy the gasket separately but the parts store had it.
