Walker Products 350-34374 oxygen sensor for the 1998-2002 Chevrolet Camaro V8 5.7L and other vehicles measures the oxygen in the exhaust gas. This Walker Products oxygen sensor is a four-wire, direct-fit narrow-band unit, and its reading shows the engine computer how efficiently the fuel is burning.
- Measures exhaust oxygen to help fine-tune the air-fuel mixture and support fuel economy
- Electrodes coated with a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors exhaust gases to help reduce pollutants
- Narrow-band sensor with four wires
Quick facts
- Part: Walker Products 350-34374 oxygen sensor
- Fits: the 1998-2002 Chevrolet Camaro V8 5.7L and other vehicles
- Position: Center, upstream left, downstream left, downstream right, downstream front
- Condition: New
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 an exhaust leak or a misfire can produce them too, so look over the wiring harness and connector for physical damage as well.
Fits
This oxygen sensor is listed for a wide range of Chevrolet, Pontiac and Cadillac models, including the 1998-2002 Pontiac Firebird V8 5.7L and the 1996-1999 Cadillac DeVille V8 4.6L. For a 2002 Camaro O2 sensor, the 1998-2002 Chevrolet Camaro V8 5.7L listing covers that model year. This listing is one sensor, and each listed application takes one. If your car is not named here, check your own car and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Does this Camaro oxygen sensor fit a 1998-2002 Chevrolet Camaro V8 5.7L?
Yes. Walker Products 350-34374 is listed for the 1998-2002 Chevrolet Camaro V8 5.7L, and that application takes one sensor.
Is this oxygen sensor right for the 1996-1999 Cadillac DeVille V8 4.6L?
Yes. Walker Products 350-34374 is listed for the 1996-1999 Cadillac DeVille V8 4.6L, as well as for V8 5.7L applications.
What thread size does the Walker Products 350-34374 oxygen sensor use?
It has an M18 - 1.5 thread and four wires. Walker Products 350-34374 is a narrow-band design.
Could a lit check engine light mean this oxygen sensor has failed?
It can, and a failed sensor may also bring rough running, higher fuel use or more emissions. A shop can read the stored fault codes to see whether the sensor is involved.
What does the coating on the electrodes of this oxygen sensor protect against?
The coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates in the exhaust gases. Walker Products 350-34374 has gas-permeable platinum electrodes.
