Walker Products 350-34128 oxygen sensor for the 1999-2002 Chevrolet Silverado 1500 V6 4.3L, V8 4.8L or 5.3L and other vehicles measures the oxygen in the exhaust gas. It is built for its specific application and sends the engine computer the diagnostic feedback it expects.
- Electrodes made of a gas-permeable platinum layer
- Reads the oxygen content of the exhaust gas to monitor the air-fuel ratio and combustion efficiency
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which helps fuel economy
- Monitors exhaust gases to help reduce pollutants

A failing oxygen sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit check engine light. A vacuum leak, a worn spark plug or damaged wiring can be behind the same signs, so inspect the sensor, harness and connector for physical damage and find the cause before you buy.

Frequently Asked Questions
Is this the right Chevy Tahoe oxygen sensor for the 1996-1999 Chevrolet Tahoe V8 5.7L?
Yes. Walker Products 350-34128 fits the 1996-1999 Chevrolet Tahoe V8 5.7L and the 2000-2002 Tahoe V8 4.8L or 5.3L. For any other car, look up its year, model and engine in the "Vehicles it fits" section.
Does this Chevy Silverado 1500 oxygen sensor fit the 1999-2002 Silverado 1500 V6 4.3L?
Yes. Walker Products 350-34128 fits the 1999-2002 Chevrolet Silverado 1500 with the V6 4.3L, and with the V8 4.8L or 5.3L. The fitment lists one sensor per vehicle.
How many wires does this Walker Products oxygen sensor have?
This oxygen sensor is a 4-wire, narrow-band design with a direct-fit build. This listing is one sensor.
What does the platinum layer on this oxygen sensor do?
The sensor's electrodes are made of a gas-permeable platinum layer. A coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces.
Does Walker Products 350-34128 interchange with CTK-OSGM4002?
Yes. CTK-OSGM4002 is listed as an interchange number for Walker Products 350-34128, so this oxygen sensor replaces it.
