Oxygen Sensor for 2004-2006 Nissan Altima & More - Walker 250-24448

Walker Products 250-24448 oxygen sensor for the 2004-2006 Nissan Altima 4-cylinder 2.5L or V6 3.5L and other vehicles measures the oxygen in the exhaust gas to show combustion efficiency. This Walker Products oxygen sensor is made for its specific application and fitting position, and it gives the ECU the diagnostic feedback it requires.

• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas
• Electrodes carry a gas-permeable platinum layer
• Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
• Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
• Narrow-band sensor with a 4-wire design

Quick facts

A rough-running engine, higher fuel use or a lit malfunction indicator light can mean the oxygen sensor is worn, though a damaged wiring harness or connector can be behind them too, so inspect both for physical damage first. This listing is one sensor; the 2004-2006 Nissan Altima 4-cylinder 2.5L or V6 3.5L takes one.

Fits

This oxygen sensor is listed for a wide range of Nissan and Infiniti models, including the 2004-2008 Nissan Maxima V6 3.5L and the 2004-2006 Nissan Sentra 4-cylinder 2.5L. For a 2006 Nissan Altima 4-cylinder 2.5L or V6 3.5L oxygen sensor, the same part number applies. Open the "Vehicles it fits" section to check your exact model and engine.
