Walker Products 350-35009 oxygen sensor for the 2004 Nissan Altima V6 3.5L, the 2004-2006 Altima 4-cylinder 2.5L and other vehicles measures the oxygen in the exhaust gas to monitor the air-fuel ratio. Each part number is made for its own application and fitment position and returns the diagnostic feedback the ECU needs.
- Measures oxygen content in the exhaust gas to track combustion efficiency
- Oxygen readings help fine-tune the air-fuel mixture, which supports fuel economy
- Monitors exhaust gases to help reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
Quick facts
- Part: Walker Products 350-35009 oxygen sensor
- Fits: the 2004 Nissan Altima V6 3.5L, the 2004-2006 Altima 4-cylinder 2.5L and other vehicles
- Position: Upstream
- Condition: New
A failing sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the malfunction indicator light. A vacuum leak can upset the air-fuel ratio too, so these signs alone do not prove the sensor is at fault. Check its wiring harness and connector for physical damage.
Fits
This upstream oxygen sensor also fits the 2004-2007 Infiniti G35 V6 3.5L, the 2003-2006 Nissan Sentra 4-cylinder 1.8L and the 2004-2006 Sentra 4-cylinder 2.5L, with one sensor per vehicle. If your car is not named here, look up its year and engine in the "Vehicles it fits" section.
