Oxygen Sensor for 2015-2018 Nissan Altima & More - Walker 250-54105

Walker Products 250-54105 oxygen sensor for the 2015-2018 Nissan Altima V6 3.5L and other vehicles measures the oxygen content of the exhaust gas. It is a 4-wire wide-band air-fuel ratio sensor that gives the ECU the diagnostic feedback it requires.

• Monitors the air-fuel ratio for combustion efficiency
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
• Electrodes made of a gas-permeable platinum layer
• Measures oxygen levels to fine-tune the air-fuel mixture, which supports fuel economy
• Monitors exhaust gases to help reduce pollutants

Quick facts

• Part: Walker Products 250-54105 oxygen sensor
• Fits: 2015-2018 Nissan Altima V6 3.5L and other vehicles
• Position: Upstream (also listed as upstream left, upstream right, upstream front and upstream rear)
• Condition: New

A failing sensor might make the engine run poorly, raise fuel consumption or exhaust emissions, or light the malfunction indicator lamp, and newer vehicles may store a related fault code in the ECU. Those signs can mean the sensor is worn, though a damaged wiring harness or connector can be behind them too, so look both over for damage.

Fits

This oxygen sensor is listed for a wide range of Nissan and Infiniti models, among them the 2013-2017 Nissan Sentra 4-cylinder 1.8L and the 2015-2019 Nissan Frontier V6 4.0L. This listing is one sensor; the 2015-2018 Nissan Altima V6 3.5L takes one.
