    Walker Products 350-34520 oxygen sensor for the 2009-2013 Mazda 6 4-cylinder 2.5L measures oxygen in the exhaust gas to report combustion efficiency. It is made for its specific application and fitment position, so the ECU gets the diagnostic feedback it expects.

    • 4-wire narrow-band sensor for the downstream position
    • Electrodes made of a gas-permeable platinum layer
    • Oxygen readings help the ECU fine-tune the air-fuel mixture for fuel economy and lower emissions
    • Electrode coating guards against contamination and erosion from combustion residue and exhaust particulates

    Quick facts

    • Part: Walker Products 350-34520 oxygen sensor
    • Fits: 2009-2013 Mazda 6 4-cylinder 2.5L
    • Position: Downstream
    • Condition: New

    A failing oxygen sensor can show up as rough running, higher fuel consumption or a check engine light. A worn spark plug can also make an engine run rough, so these signs alone do not prove the sensor is at fault.

    Fits

    This Walker Products oxygen sensor is a direct-fit replacement for the 2009-2013 Mazda 6 4-cylinder 2.5L. This listing is one downstream sensor, and that engine takes one.

    Frequently Asked Questions

    Is this an oxygen sensor replacement for the 2009-2013 Mazda 6 4-cylinder 2.5L?

    Yes. Walker Products 350-34520 is a direct-fit downstream oxygen sensor for the 2009-2013 Mazda 6 4-cylinder 2.5L, and that engine takes one.

    Is this Walker Products oxygen sensor upstream or downstream?

    It is a downstream sensor. Walker Products 350-34520 is a narrow-band type.

    How many wires and what thread does this narrow-band oxygen sensor have?

    This sensor has four wires and an M18 - 1.5 thread.

    Can a failing oxygen sensor turn on the check engine light?

    Yes, a failed sensor can light the malfunction indicator lamp, along with rough running or higher fuel use. A shop can read the stored codes.

    What is the platinum layer on this oxygen sensor for?

    The electrodes are made of a gas-permeable platinum layer. A coating on the electrode surfaces protects them from contamination and erosion by combustion residue and particulates.
