Walker Products 250-24334 oxygen sensor for the 2002-2005 Chevrolet Cavalier 4-cylinder 2.2L and other vehicles measures the oxygen content of the exhaust gas. This downstream oxygen sensor is a direct-fit, narrow-band unit with four wires.
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Coating 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
- Monitors exhaust gases to help reduce pollutants
- Measures oxygen levels to help fine-tune the air-fuel mixture and fuel economy
Quick facts

A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is the problem, since a vacuum leak is another common source of them. Newer vehicles also store fault codes in the ECU, and some relate to the sensor.

Frequently Asked Questions
Is this the right oxygen sensor for the 2002-2005 Chevrolet Cavalier 4-cylinder 2.2L?
Yes. Walker Products 250-24334 is a direct-fit downstream oxygen sensor for the 2002-2005 Chevrolet Cavalier 4-cylinder 2.2L.
Will this oxygen sensor fit the 2002-2005 Pontiac Sunfire 4-cylinder 2.2L?
Yes. This sensor goes in the downstream position on the 2002-2005 Pontiac Sunfire 4-cylinder 2.2L, and that engine takes one.
Is this Walker Products oxygen sensor narrow-band or wideband?
Narrow-band. Walker Products 250-24334 is a 4-wire sensor that measures the oxygen content of the exhaust gas to track combustion efficiency.
What is the platinum layer on this oxygen sensor's electrodes?
The electrodes are made of a gas-permeable platinum layer, and a coating guards their surfaces against combustion residue and particulates that would contaminate or erode them.
Should I check the wiring when this downstream oxygen sensor seems to be failing?
Yes. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage, because damage can shorten the sensor's operating life.
