Walker Products 350-34273 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 in the exhaust gas. It is a direct-fit sensor made for its specific application and fitment position.
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors exhaust gases to help reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Oxygen readings let the air-fuel mixture be fine-tuned for fuel economy
Quick facts
- Part: Walker Products 350-34273 oxygen sensor
- Fits: the 2007-2012 Nissan Altima V6 3.5L, the 2007-2013 Altima 4-cylinder 2.5L and other vehicles
- Condition: New
A failing sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or switch on the malfunction indicator light. A damaged wiring harness or connector, or another engine management sensor, can be behind the same signs, so find the cause before you buy a sensor. With the engine off and cool, look the sensor, harness and connector over for physical damage.
Fits
This oxygen sensor is listed for a wide range of Nissan and Infiniti models, including a 2008 Nissan Altima with the V6 3.5L or the 4-cylinder 2.5L, the 2009-2014 Nissan Maxima V6 3.5L and the 2009-2011 Nissan Murano V6 3.5L. The quantity is one sensor per vehicle, and this listing is one sensor. Open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Is this the right oxygen sensor for a 2009-2014 Nissan Maxima V6 3.5L?
Yes. Walker Products 350-34273 is listed for the 2009-2014 Nissan Maxima V6 3.5L, and that car takes one sensor.
Does this oxygen sensor fit a 2009-2011 Nissan Murano V6 3.5L?
Yes. Walker Products 350-34273 is listed for the 2009-2011 Nissan Murano V6 3.5L, and the quantity is one.
What does this Walker Products oxygen sensor monitor?
This oxygen sensor reads the oxygen content of the exhaust gas and uses it to track the air-fuel ratio and combustion efficiency.
What thread size and wire count does this narrow-band oxygen sensor have?
Walker Products 350-34273 has an M18 - 1.5 thread and is a 4-wire narrow-band sensor.
Will a failing oxygen sensor store a fault code on a newer car?
Yes, it can. Newer vehicles store fault codes in the ECU, and some of them relate to the affected sensor and its associated systems.
