    Walker Products 250-24859 oxygen sensor for the 2009-2013 Mazda 6 4-cylinder 2.5L measures exhaust oxygen to help fine-tune the air-fuel mixture. This downstream sensor gives the ECU the diagnostic feedback this application calls for.

    • Monitors exhaust gases to help reduce pollutants
    • Electrodes made with a gas-permeable platinum layer
    • Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
    • Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
    • Narrow-band design with 4 wires

    Quick facts

    • Part: Walker Products 250-24859 oxygen sensor
    • Fits: 2009-2013 Mazda 6 4-cylinder 2.5L

    Frequently Asked Questions

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

    Yes. Walker Products 250-24859 is a downstream oxygen sensor for the 2009-2013 Mazda 6 4-cylinder 2.5L (L4-2.5L), and that engine takes one.

    Is this Walker Products oxygen sensor narrow-band or wideband?

    It is narrow-band. Walker Products 250-24859 has 4 wires and an M18 - 1.5 thread.

    What protects the electrodes on this oxygen sensor?

    The electrodes have a gas-permeable platinum layer, and a coating guards their surfaces against contamination and erosion from combustion residue and particulates.

    Will a failing oxygen sensor set a fault code?

    It can. Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems.

    Is this downstream oxygen sensor made for a specific position on the car?

    Yes. Every Walker Products part number is made for its specific application and fitment position, and 250-24859 is a downstream sensor.
