Walker Products 350-64072 oxygen sensor for the 2007-2011 Nissan Altima 4-cylinder 2.5L, the 2008-2010 Altima V6 3.5L and other vehicles measures the oxygen in the exhaust gas to show how efficiently combustion is running. This Walker Products oxygen sensor is made for its specific application and fitment position, and it sends the diagnostic feedback the ECU needs.
- Wide-band, 4-wire air-fuel ratio sensor that tracks combustion efficiency from exhaust oxygen content
- Measures oxygen levels in the exhaust to fine-tune the air-fuel mixture
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Monitors exhaust gases and helps reduce pollutants
- Gas-permeable platinum layer on the coated electrodes
Quick facts
- Part: Walker Products 350-64072 oxygen sensor
- Fits: the 2007-2011 Nissan Altima 4-cylinder 2.5L, the 2008-2010 Altima V6 3.5L and other vehicles
- Position: Upstream, upstream left, upstream right, upstream front
- Condition: New
A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light, though the wiring harness and the connector can be behind the same signs, so look both over for physical damage before replacing the sensor.
Fits
The 2007-2011 Nissan Altima 4-cylinder 2.5L and the 2008-2010 Altima V6 3.5L take this sensor, so a 2008 Nissan Altima oxygen sensor in either engine is covered, along with the 2011-2012 Nissan Sentra 4-cylinder 2.5L, the 2007-2010 Nissan Pathfinder V6 4.0L and the 2008-2012 Pathfinder V8 5.6L. It fits other vehicles too. Each takes one, and this listing is one sensor.
