    Walker Products 350-34640 oxygen sensor for the 2002-2009 Mini Cooper 4-cylinder 1.6L measures the oxygen in the exhaust gas to gauge combustion efficiency. It is made for its specific application and fitment position, and it sends the diagnostic feedback the ECU requires.

    • Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
    • Monitors exhaust gases to help reduce pollutants
    • Electrodes made of a gas-permeable platinum layer
    • Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
    • Narrow-band sensor with four wires

    Quick facts

    • Part: Walker Products 350-34640 oxygen sensor
    • Fits: 2002-2009 Mini Cooper 4-cylinder 1.6L
    • Position: Upstream, downstream

    A worn sensor can show up as rough running, higher fuel use or a lit malfunction indicator light. None of that alone proves the sensor is the problem; a damaged wiring harness is another common cause.

    Fits

    Frequently Asked Questions

    Is this the right O2 sensor for the 2002-2009 Mini Cooper 4-cylinder 1.6L?

    Yes. Walker Products 350-34640 is a direct-fit oxygen sensor for the 2002-2009 Mini Cooper 4-cylinder 1.6L, and that car takes one.

    How many wires does this Walker Products oxygen sensor have?

    Walker Products 350-34640 is a 4-wire, narrow-band oxygen sensor.

    Does this oxygen sensor have a platinum electrode layer?

    Yes. The electrodes are made of a gas-permeable platinum layer, and a coating protects them from combustion residue and particulates in the exhaust gases.

    Will a failing oxygen sensor set 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.

    Does Walker Products 350-34640 interchange with CTK-OSMN4002?

    Yes. CTK-OSMN4002 is listed as an interchange number for Walker Products 350-34640.
