    Walker Products 350-34573 front oxygen sensor for the 2003-2008 Mazda 6 V6 3.0L measures the oxygen content of the exhaust gas. This 4-wire narrow-band sensor is made for its specific position and gives the ECU diagnostic feedback.

    • Monitors the air-fuel ratio in the exhaust gas for combustion efficiency
    • Oxygen readings help fine-tune the air-fuel mixture for fuel economy
    • Monitors exhaust gases to help reduce pollutants
    • Electrodes with a gas-permeable platinum layer
    • Electrode coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates

    Quick facts

    • Part: Walker Products 350-34573 oxygen sensor
    • Fits: 2003-2008 Mazda 6 V6 3.0L
    • Position: Upstream front
    • Condition: New

    A failing sensor can show up as rough running, higher fuel consumption, more emissions or a lit malfunction indicator light. These signs alone do not prove the sensor is at fault; a vacuum leak, for example, can cause rough running too. Also look over the sensor, wiring harness and connector for physical damage with the engine off and cool.
