Walker Products 250-24267 oxygen sensor for the 2007 Chevrolet Silverado 1500 V8 4.8L, 5.3L or 6.0L and other vehicles measures the oxygen in the exhaust gas to show combustion efficiency. This Walker Products oxygen sensor is a 4-W direct fit narrow-band unit, made for its specific application and fitment position to give the ECU the diagnostic feedback it expects.
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and exhaust particulates
- Monitors the air-fuel ratio to help fine-tune combustion efficiency and fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 250-24267 oxygen sensor
- Fits: 2007 Chevrolet Silverado 1500 V8 4.8L, 5.3L or 6.0L and other vehicles
- Position: upstream, downstream, upstream left, downstream left, downstream right, downstream front, downstream rear
- Condition: New
A failing sensor can show up as poor running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, and other faults can cause those signs too. Before replacing it, look over the sensor, its wiring harness and the connector for physical damage with the engine off and cool; damage there can shorten the sensor's life, and a shop can read any stored fault code.
Fits
The 2007 Chevrolet Silverado 1500 V8 4.8L, 5.3L or 6.0L, the 2004-2007 Chevrolet Malibu V6 3.5L and the 2006-2007 Malibu V6 3.9L, and the 2003-2005 GMC Sierra 1500 V8 6.0L all take this sensor, as do many other vehicles. This listing is one sensor, and each of these vehicles is listed with a quantity of one.

Frequently Asked Questions
Does this Malibu oxygen sensor fit the 2006-2007 Chevrolet Malibu V6 3.9L?
Yes. Walker Products 250-24267 is listed for the 2006-2007 Chevrolet Malibu V6 3.9L and the 2004-2007 Malibu V6 3.5L. If your car is not named here, run its year and engine through the "Vehicles it fits" section.
What thread size does the Walker Products 250-24267 oxygen sensor have?
The Walker Products 250-24267 has a threaded M18 - 1.5 body.
Is this oxygen sensor narrow-band or wideband?
It is narrow-band. This oxygen sensor is a 4-W direct fit narrow-band type that reports the oxygen content of the exhaust gas.
Can a worn oxygen sensor raise fuel consumption or light the malfunction indicator?
Yes, it can. A failed sensor may make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the malfunction indicator light, and newer vehicles may store a related fault code.
Which position is the Walker Products 250-24267 oxygen sensor made for?
The catalog lists upstream, downstream, upstream left, downstream left, downstream right, downstream front and downstream rear. Walker Products 250-24267 is made for its specific application and fitment position.
