Walker Products 250-54035 oxygen sensor for the 2007-2013 Nissan Altima 4-cylinder 2.5L, the 2011-2012 Altima V6 3.5L and other vehicles measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor is a 4-W air fuel ratio wide-band unit that reads combustion efficiency from the amount of oxygen in that gas.
- Wide-band air fuel ratio sensing of the oxygen in the exhaust gas
- Electrodes made of a gas-permeable platinum layer
- Coating that prevents contamination and erosion of the electrode surfaces by combustion residue and particulates
- Oxygen readings that let the air-fuel mixture be fine-tuned, which helps fuel economy
- Built for a specific application and fitment position, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 250-54035 oxygen sensor
- Fits: 2007-2013 Nissan Altima 4-cylinder 2.5L, the 2011-2012 Altima V6 3.5L and other vehicles
- Position: Upstream
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption or a malfunction indicator light, though a damaged wiring harness or connector can be behind the same signs, so look those over for physical damage before you replace the sensor.
Fits
This direct-fit replacement is listed for a wide range of Nissan, Infiniti and Suzuki models, led by the 2007-2013 Nissan Altima 4-cylinder 2.5L, the 2011-2012 Altima V6 3.5L, the 2010-2012 Nissan Sentra 4-cylinder 2.0L and the 2011-2012 Nissan Frontier V6 4.0L.

Frequently Asked Questions
Is this the right Nissan Sentra oxygen sensor for a 2010-2012 model with the 4-cylinder 2.0L?
Yes. Walker Products 250-54035 is listed for the 2010-2012 Nissan Sentra 4-cylinder 2.0L, and that Sentra takes one sensor.
Is this a 2013 Nissan Altima oxygen sensor for the 4-cylinder 2.5L?
Yes. It is listed for the 2007-2013 Nissan Altima 4-cylinder 2.5L and the 2011-2012 Altima V6 3.5L. For other models, open the "Vehicles it fits" section.
Is this oxygen sensor a wide-band air fuel ratio type?
Yes. Walker Products 250-54035 is a 4-W air fuel ratio wide-band sensor with electrodes made of a gas-permeable platinum layer.
Can a bad wide-band oxygen sensor turn on the malfunction indicator light?
Yes, it can. A failed sensor may also lead to rough running or higher fuel consumption, and newer vehicles can store fault codes in the ECU. A shop can read the codes and test the sensor.
What does the coating on this oxygen sensor's electrodes do?
The coating keeps combustion residue and particulates in the exhaust gases from contaminating or eroding the electrode surfaces.
