Walker Products 250-24771 oxygen sensor for the 2007-2012 Nissan Altima V6 3.5L, the 2007-2013 Altima 4-cylinder 2.5L and other vehicles measures the oxygen content of the exhaust gas to show how efficiently combustion is running.
- Measures exhaust oxygen levels to fine-tune the air-fuel mixture and support fuel economy
- Monitors exhaust gases to help reduce pollutants
- Electrodes with a gas-permeable platinum layer
- Electrode coating resists contamination and erosion from combustion residue and particulates in the exhaust
- Narrow-band, 4-wire sensor made for its specific application and position on the vehicle, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 250-24771 oxygen sensor
- Fits: 2007-2012 Nissan Altima V6 3.5L, the 2007-2013 Altima 4-cylinder 2.5L and other vehicles
- Position: Center, upstream, downstream, downstream left, downstream right, downstream front, downstream rear
- Condition: New
A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. A vacuum leak can also make an engine run poorly, so these signs alone don't prove the sensor is at fault. With the engine off and cool, look the sensor, harness and connector over for damage.
Fits
As an oxygen sensor for the 2009-2011 Nissan Murano V6 3.5L and the 2009-2014 Nissan Maxima V6 3.5L, it is a direct-fit part, and it fits many other vehicles as well. If your car isn't named here, look up its year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the oxygen sensor for the 2009-2014 Nissan Maxima V6 3.5L?
Yes. Walker Products 250-24771 fits the 2009-2014 Nissan Maxima V6 3.5L, and that car takes one sensor. If your car isn't the one named, use the "Vehicles it fits" section.
Is this the right oxygen sensor for a 2013 Nissan Altima 4-cylinder 2.5L?
Yes. The 2007-2013 Nissan Altima 4-cylinder 2.5L is in the fitment for Walker Products 250-24771, and that range includes the 2013 model year.
Is this Walker Products oxygen sensor narrow-band or wideband?
It is narrow-band. Walker Products 250-24771 is a 4-wire narrow-band sensor with a threaded body.
Can a failing oxygen sensor turn on the check engine light?
Yes, it can. A failed sensor can light the malfunction indicator light, and newer vehicles store fault codes in the ECU, some tied to the sensor and its related systems.
What protects the electrodes on this oxygen sensor?
A coating on the electrode surfaces guards against contamination and erosion from combustion residue and particulates in the exhaust gas. The electrodes carry a gas-permeable platinum layer.
