    Walker Products 250-23028 oxygen sensor for the 1994-1998 Audi Cabriolet V6 2.8L and other vehicles measures the oxygen in the exhaust gas. The Walker Products oxygen sensor tracks combustion efficiency, is made for its specific application and fitment position, and gives the ECU the diagnostic feedback it needs.

    • 3-wire, narrow-band design
    • Electrodes made of a gas-permeable platinum layer
    • Coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates
    • Monitors exhaust gases to help reduce pollutants

    Quick facts

    • Part: Walker Products 250-23028 oxygen sensor
    • Fits: 1994-1998 Audi Cabriolet V6 2.8L and other vehicles
    • Position: upstream, downstream, upstream left, upstream right
    • Condition: New

    Rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light can mean the sensor is worn, though its wiring harness or connector can be behind them too, so look both over for physical damage.

    Fits

    The vehicles it fits include the 1994-1998 Audi Cabriolet V6 2.8L, the 1995-1997 Audi A6 V6 2.8L and the 1995-1997 Audi A6 Quattro V6 2.8L. This listing is one sensor, and the fitment calls for one per position.

    Frequently Asked Questions

    Is this Audi A6 oxygen sensor right for the 1995-1997 V6 2.8L?

    Yes. Walker Products 250-23028 is listed for the 1995-1997 Audi A6 V6 2.8L. If your car is a different one, enter it in the "Vehicles it fits" section to see whether this sensor is listed for it.

    Is the Walker Products 250-23028 a narrow-band or wideband sensor?

    It is a narrow-band sensor with 3 wires and a direct-fit design. Its electrodes are made of a gas-permeable platinum layer.

    What does the coating on this oxygen sensor protect?

    The coating keeps combustion residue and particulates in the exhaust gases from contaminating or eroding the electrode surfaces.

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

    Yes. A lit malfunction indicator light, poor running, or higher fuel use and emissions can go with a failed oxygen sensor, and newer vehicles may store a related fault code in the ECU.

    What does this oxygen sensor report to the ECU?

    Walker Products 250-23028 determines the oxygen content of the exhaust gas and tracks the air-fuel ratio, so the ECU can follow combustion efficiency.
