Walker Products 250-24355 oxygen sensor for the 2006 Chevrolet Silverado 1500 V8 4.8L, the 2007 Silverado 1500 V6 4.3L and other vehicles measures the oxygen left in the exhaust gas. Its readings tell the engine computer how the combustion is going.
- Monitors exhaust gases and reduces pollutants
- Monitors the air-fuel ratio for combustion efficiency and fine-tunes the mixture to help fuel economy
- Electrodes with a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Narrow-band, 4-wire design made for its specific application and position on the vehicle
Quick facts
- Part: Walker Products 250-24355 oxygen sensor
- Fits: the 2006 Chevrolet Silverado 1500 V8 4.8L, the 2007 Silverado 1500 V6 4.3L and other vehicles
- Position: Upstream, downstream, upstream right, downstream left, downstream right
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. A damaged wiring harness or connector can be behind the same signs, so find the cause before buying. With the engine off and cool, look the sensor, harness and connector over for physical damage.
Fits
The 2006-2007 Chevrolet Tahoe V8 4.8L, the 2007 Tahoe V8 5.3L, the 2006-2007 GMC Yukon V8 4.8L and the 2007 Yukon V8 5.3L or 6.2L all take this sensor as a direct-fit replacement. It also works as a Chevy Silverado 1500 oxygen sensor for the 2006 V8 4.8L and the 2007 V6 4.3L. This listing is one sensor, and the fitment calls for one per vehicle. If your car isn't named here, look it up by year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this a Chevy Tahoe oxygen sensor for the 2006-2007 Tahoe V8 4.8L?
Yes. Walker Products 250-24355 fits the 2006-2007 Chevrolet Tahoe V8 4.8L and the 2007 Tahoe V8 5.3L. Other vehicles and engines can be looked up in the "Vehicles it fits" section.
Is this a GMC Yukon oxygen sensor for the 2007 Yukon V8 6.2L?
Yes. Walker Products 250-24355 fits the 2006-2007 GMC Yukon V8 4.8L and the 2007 Yukon V8 5.3L or 6.2L, one sensor per vehicle.
Is the Walker Products 250-24355 an upstream or downstream sensor?
Both kinds are covered: this number is catalogued for upstream, downstream, upstream right, downstream left and downstream right positions.
Can a failing narrow-band oxygen sensor turn on the check engine light?
Yes. A failed sensor can light the malfunction indicator light, and it can also come with rough running or higher fuel consumption. Newer vehicles store fault codes that a shop can read.
What does the coating on this oxygen sensor protect?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas. The electrodes carry a gas-permeable platinum layer.
