Walker Products 250-24453 oxygen sensor for the 2008-2012 Nissan Pathfinder V8 5.6L and other vehicles measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor is a 4-wire, narrow-band unit made for its specific application and fitment position.
- Monitors the air-fuel ratio by reading oxygen in the exhaust, for combustion efficiency
- Oxygen readings are used to fine-tune the air-fuel mixture and support fuel economy
- Monitors exhaust gases to help reduce pollutants
- Electrodes with a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and exhaust particulates
Quick facts
- Part: Walker Products 250-24453 oxygen sensor
- Fits: 2008-2012 Nissan Pathfinder V8 5.6L and other vehicles
- Position: Upstream, downstream, downstream left, downstream right
- Condition: New
A failing oxygen sensor can show up as the engine running poorly, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Before you replace it, rule out a damaged wiring harness or connector and read any stored fault codes, since newer vehicles log codes tied to the sensor and its related systems.
Fits
Beyond the 2008-2012 Nissan Pathfinder V8 5.6L, it is an oxygen sensor for the 2004-2015 Nissan Titan V8 5.6L and the 2003-2006 Nissan Sentra 4-cylinder 1.8L, among others. If your car is not named here, look up its year and engine under the "Vehicles it fits" section. This listing is one sensor, and the fitment calls for one per application.

Frequently Asked Questions
Is this a Nissan Sentra oxygen sensor for a 2003-2006 Sentra with the 4-cylinder 1.8L engine?
Yes. Walker Products 250-24453 is listed for the 2003-2006 Nissan Sentra 4-cylinder 1.8L, with one sensor per application.
What type of oxygen sensor is the Walker Products 250-24453?
Walker Products 250-24453 is a narrow-band, 4-wire oxygen sensor with an M18 - 1.5 thread, sold as one sensor per listing.
Is this an upstream or downstream oxygen sensor?
This part number is listed for upstream, downstream, downstream left and downstream right positions.
What does the platinum layer on this oxygen sensor do?
The electrodes carry a gas-permeable platinum layer. The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases.
Does the Walker Products 250-24453 fit the 2004-2015 Nissan Titan V8 5.6L?
Yes. Walker Products 250-24453 is listed for the 2004-2015 Nissan Titan V8 5.6L, with one sensor per application.
