Walker Products 250-24018 oxygen sensor for the 1996-1999 Chevrolet Silverado V8 5.7L and other vehicles measures the oxygen in the exhaust gas and gives the ECU the diagnostic feedback it needs. This Walker Products oxygen sensor is a four-wire, narrow-band, direct-fit design made for its specific application and fitment position.
- Exhaust gas monitoring that reduces pollutants for a cleaner environment
- Oxygen content readings that track the air-fuel ratio for combustion efficiency and let the mixture be fine-tuned to improve fuel economy
- Coating that protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Electrodes made of a gas-permeable platinum layer
Quick facts
- Part: Walker Products 250-24018 oxygen sensor
- Fits: the 1996-1999 Chevrolet Silverado V8 5.7L and other vehicles
- Position: Upstream, downstream, upstream left, upstream right, downstream left, downstream right, upstream rear, upstream front
- Condition: New
A failing sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or light the malfunction indicator light. Several other problems can look just like these, so find the cause first: with the engine off and cool, look over the sensor, wiring harness and connector for physical damage, which can also shorten sensor life.
Fits
Listed for a wide range of Chevrolet, GMC, Cadillac, Buick, Oldsmobile and Pontiac models, it works as a Chevy Tahoe oxygen sensor for the 1996-2000 Chevrolet Tahoe V8 5.7L and the 2000-2002 Tahoe V8 4.8L or 5.3L. It is also an O2 sensor Silverado owners can fit to the 1999-2002 Chevrolet Silverado 1500 with the V6 4.3L, V8 4.8L or V8 5.3L. This listing is one sensor, and the fitment calls for one per application.

Frequently Asked Questions
Is this the right Chevy Silverado oxygen sensor for a 1996-1999 Silverado V8 5.7L?
Yes, Walker Products 250-24018 is listed for the 1996-1999 Chevrolet Silverado V8 5.7L. If your truck is a different model, look up its year and engine in the "Vehicles it fits" section.
Does this O2 sensor for Chevy Silverado 1500 trucks fit the 1999-2002 model with the V8 5.3L?
Yes. Walker Products 250-24018 is listed for the 1999-2002 Chevrolet Silverado 1500 with the V6 4.3L, V8 4.8L or V8 5.3L.
What is the coating on this oxygen sensor for?
The coating keeps combustion residue and particulates in the exhaust gases from contaminating and eroding the electrode surfaces. The electrodes themselves are made of a gas-permeable platinum layer.
What thread size and wire count does this narrow-band oxygen sensor have?
This narrow-band oxygen sensor has an M18 - 1.5 thread and four wires.
Will a failing oxygen sensor set a fault code on a newer vehicle?
Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems. A shop can read those codes and test the sensor with the engine running.
