    Walker Products 250-25063 oxygen sensor for the 2010-2013 Mazda 3 4-cylinder 2.5L measures the oxygen in the exhaust gas. This heated wide-band upstream sensor is made for its specific application and fitment position, and it provides the diagnostic feedback the ECU requires.

    • Measures oxygen levels in the exhaust to help fine-tune the air-fuel mixture for fuel economy
    • Monitors exhaust gases and the air-fuel ratio for combustion efficiency and reduces pollutants
    • Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas
    • Electrodes made of a gas-permeable platinum layer

    Quick facts

    • Part: Walker Products 250-25063 oxygen sensor
    • Fits: 2010-2013 Mazda 3 4-cylinder 2.5L

    Frequently Asked Questions

    Is Walker Products 250-25063 an oxygen sensor replacement for the 2010-2013 Mazda 3 4-cylinder 2.5L?

    Yes. Walker Products 250-25063 fits the 2010-2013 Mazda 3 4-cylinder 2.5L as its upstream oxygen sensor, and each car takes one.

    Is this 2010 Mazda 3 oxygen sensor for the 4-cylinder 2.5L an upstream or downstream sensor?

    Upstream. Walker Products 250-25063 is an upstream sensor, and the 2010-2013 Mazda 3 4-cylinder 2.5L takes one.

    Is this oxygen sensor wide-band and heated, and how long is its wiring harness?

    Yes, it is a heated wide-band sensor with a threaded mount and a 325 mm wiring harness. It has five wires and five spade terminals.

    Will a failing upstream oxygen sensor store a fault code?

    Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems. A shop can read them to help find the cause.

    What does the coating on this platinum-electrode oxygen sensor protect?

    The coating keeps combustion residue and particulates in the exhaust gas from contaminating or eroding the electrode surfaces. The electrodes are made of a gas-permeable platinum layer.
