Walker Products 250-24131 oxygen sensor for the 2004-2011 Mazda RX-8 1.3L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. The part is made for its specific application and fitment position, and it gives the ECU the diagnostic feedback it needs.
- Narrow-band oxygen sensor with 4 wires
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust
- Monitors exhaust gases and helps reduce pollutants
Quick facts
- Part: Walker Products 250-24131 oxygen sensor
- Fits: 2004-2011 Mazda RX-8 1.3L and other vehicles
- Position: Downstream
- Condition: New
Rough running, higher fuel consumption and a lit malfunction indicator light can mean this sensor has failed, though a damaged wiring harness or connector may be behind them too, so inspect both for physical damage on a cool engine. If the sensor is the cause, this one replaces it.
Fits
It is a downstream oxygen sensor for the 2004-2011 Mazda RX-8 1.3L and the 1996-1998 Mazda MPV V6 3.0L.

Frequently Asked Questions
Is this the right oxygen sensor for a 1996-1998 Mazda MPV V6 3.0L?
Yes. Walker Products 250-24131 is listed for the 1996-1998 Mazda MPV V6 3.0L as a downstream sensor, and that engine takes one.
Is this Walker Products oxygen sensor narrow-band or wideband?
Narrow-band. Walker Products 250-24131 is a narrow-band sensor with 4 wires.
What protects the electrodes in this oxygen sensor?
The electrodes are made of a gas-permeable platinum layer. A coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces.
Will a failed 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 the codes to see whether this sensor is involved.
How does this oxygen sensor help fuel economy?
Walker Products 250-24131 measures the oxygen level in the exhaust so the air-fuel mixture can be fine-tuned, which supports fuel economy.
