Walker Products 250-54102 oxygen sensor for the 2013-2014 Nissan Altima V6 3.5L, the 2013-2017 Altima 4-cylinder 2.5L and other vehicles measures the oxygen in the exhaust gas to report combustion efficiency. The Walker Products oxygen sensor is a 4-W wide-band air-fuel ratio unit made for its specific application and fitment position, and it gives the ECU the diagnostic feedback it requires.

• Wide-band air-fuel ratio sensor that determines the oxygen content of the exhaust gas
• Monitors exhaust gases to help reduce pollutants
• Oxygen readings let the air-fuel mixture be fine-tuned for fuel economy
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
• Electrodes made with a gas-permeable platinum layer

Quick facts

• Position: Upstream
• Condition: New

A failing sensor can show up as an engine that runs poorly, higher fuel consumption or emissions, or a lit malfunction indicator light. Before you replace the sensor, rule out physical damage to its wiring harness and connector, and have a shop read any stored fault codes to see which sensor is flagged. This listing is one sensor; where a car has upstream sensors on the left and right or front and rear, each position takes its own.

Fits

Vehicles it fits include the 2013-2019 Nissan Sentra 4-cylinder 1.8L. It is also an oxygen sensor for the 2013-2015 Nissan Frontier 4-cylinder 2.4L or V6 4.0L and the 2013-2019 Frontier 4-cylinder 2.5L.
