Walker Products 350-32028 oxygen sensor for the 2000-2003 Chevrolet S10 4-cylinder 2.2L and other vehicles measures the oxygen in the exhaust gas to show combustion efficiency. This upstream Walker Products oxygen sensor is a direct-fit, narrow-band design.
- Electrodes with a gas-permeable platinum layer
- Monitors exhaust gases and reduces pollutants
- Determines the oxygen content of the exhaust gas, monitoring the air fuel ratio for combustion efficiency
- Measures oxygen levels to help fine-tune the air-fuel mixture and fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas
Quick facts

Frequently Asked Questions
Is this the right Chevy S10 oxygen sensor for the 2000-2003 Chevrolet S10 4-cylinder 2.2L?
Yes. Walker Products 350-32028 is listed for the 2000-2003 Chevrolet S10 4-cylinder 2.2L in the upstream position. It also fits other vehicles; the "Vehicles it fits" section shows yours.
Is the Walker Products 350-32028 sold as a single oxygen sensor?
Yes. Walker Products 350-32028 is one upstream oxygen sensor, and the fitment lists a quantity of one.
What thread size does this upstream oxygen sensor have?
This upstream oxygen sensor has an M18 - 1.5 thread. It is a narrow-band sensor.
What can a failing oxygen sensor cause in normal driving?
Rough running, higher fuel use or a lit malfunction indicator light. A shop can read the stored ECU fault codes to see which sensor is involved.
What does the coating on this oxygen sensor protect against?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas.
