Walker Products 250-24286 oxygen sensor for the 2001 Nissan Pathfinder V6 3.5L and other vehicles reads the oxygen level in the exhaust gas for the engine computer. Each Walker part number is made for its specific application and fitment position, and gives the diagnostic feedback the ECU expects.
- Monitors the air-fuel ratio from the exhaust oxygen content to track combustion efficiency
- Narrow-band sensor with 4 wires
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 250-24286 oxygen sensor
- Fits: 2001 Nissan Pathfinder V6 3.5L and other vehicles
- Position: Downstream right, downstream rear
- Condition: New
A failing sensor can show up as the engine running poorly, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. These signs alone don't prove the sensor is at fault; a damaged wiring harness or connector can give similar trouble, so inspect those for physical damage too.
Fits
This direct-fit oxygen sensor is listed for a wide range of Nissan and Infiniti models, including the 2001 Nissan Pathfinder V6 3.5L, the 1998-2001 Nissan Maxima V6 3.0L and the 1999-2001 Infiniti I30 V6 3.0L. It is made for the downstream right and downstream rear position, and the listing is one sensor, matching the quantity of one given for each application. A sensor for another position is a separate part. Driving something else? Look up your year, make and engine in the "Vehicles it fits" section to see if this sensor is listed for it.

Frequently Asked Questions
Does this work as the oxygen sensor for a 1998-2001 Nissan Maxima V6 3.0L?
Yes, Walker Products 250-24286 is listed for the 1998-2001 Nissan Maxima V6 3.0L in the downstream right, downstream rear position. If your car is not named here, use the "Vehicles it fits" section.
Is this the right oxygen sensor for the 2001 Nissan Pathfinder V6 3.5L?
Yes, the 2001 Nissan Pathfinder V6 3.5L is listed for this sensor, which takes one in the downstream right, downstream rear position.
How many wires does the Walker Products 250-24286 oxygen sensor have?
Walker Products 250-24286 is a narrow-band oxygen sensor with 4 wires.
What signs can show that a downstream oxygen sensor is wearing out?
The engine may run poorly, fuel consumption and exhaust emissions may rise, or the malfunction indicator light may come on. A shop can read the stored fault codes to see which sensor they relate to.
What protects the electrodes in this Walker Products oxygen sensor?
The electrodes are made of a gas-permeable platinum layer, and a coating on the electrode surfaces guards them against contamination and erosion from combustion residue and particulates in the exhaust gas.
