Walker Products 250-24703 oxygen sensor for the 2006 Chevrolet Silverado 1500 V8 4.8L or 5.3L, the 2007-2013 Silverado 1500 V6 4.3L and other vehicles measures the oxygen in the exhaust gas to show how completely the engine burns its fuel. Each Walker part number is built for its specific application and fitment position, and gives the diagnostic feedback the ECU needs.
- Narrow-band sensor with four wires
- Gas-permeable platinum layer on the electrodes
- Coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
Quick facts
- Part: Walker Products 250-24703 oxygen sensor
- Fits: 2006 Chevrolet Silverado 1500 V8 4.8L or 5.3L, the 2007-2013 Silverado 1500 V6 4.3L and other vehicles
- Position: Upstream, downstream, upstream left, upstream right, downstream left, downstream front
- Condition: New
A rough-running engine, higher fuel use, more exhaust emissions or a lit malfunction indicator light can be signs of a failing sensor. They do not prove it, though, because a damaged wiring harness or connector is another common cause, and both are worth a look with the engine off.

Frequently Asked Questions
Is this the right Chevy Tahoe oxygen sensor for a 2006-2007 Tahoe V8 4.8L or 5.3L?
Yes. Walker Products 250-24703 fits the 2006-2007 Chevrolet Tahoe with the V8 4.8L or V8 5.3L engine. The listing is one sensor, and each application takes one.
Does this GMC Yukon oxygen sensor fit the 2006-2007 Yukon V8 4.8L or 5.3L and the 2007 Yukon V8 6.2L?
Yes. Walker Products 250-24703 fits the 2006-2007 GMC Yukon V8 4.8L or 5.3L and the 2007 GMC Yukon V8 6.2L.
Is the Walker Products 250-24703 a narrow-band or wideband sensor?
It is a narrow-band sensor with four wires. Walker Products 250-24703 is sold as a direct-fit oxygen sensor.
Can a failing Walker Products 250-24703 oxygen sensor turn on the check engine light?
Yes. A failed sensor can light the malfunction indicator light, make the engine run poorly or raise fuel consumption, and newer vehicles may store a fault code in the ECU for a shop to read.
What does the coating on this oxygen sensor protect?
A coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes use a gas-permeable platinum layer.
