Walker Products 350-34076 oxygen sensor for the 2000-2003 Chevrolet Impala V6 3.8L, the 2000-2004 Impala V6 3.4L and other vehicles measures the oxygen in the exhaust gas so the ECU can track combustion efficiency. Each part number is made for a specific application and fitment position, and it returns the diagnostic feedback the ECU needs.
- Determines the oxygen content of the exhaust gas and monitors the air fuel ratio for combustion efficiency
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Oxygen readings let the air-fuel mixture be fine-tuned to support fuel economy
- Monitors exhaust gases to help reduce pollutants
- Electrodes made of a gas-permeable platinum layer
Quick facts
- Part: Walker Products 350-34076 oxygen sensor
- Fits: 2000-2003 Chevrolet Impala V6 3.8L, the 2000-2004 Impala V6 3.4L and other vehicles
- Position: center, upstream, downstream, upstream left, upstream right, downstream right, downstream front or downstream rear, depending on the application
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, though a different fault could produce the same symptoms. Before you replace it, look over the sensor, its wiring harness and the connector for physical damage with the engine off and cool.
Fits
It is an oxygen sensor for the 1996-2002 Chevrolet Camaro V6 3.8L or V8 5.7L, the 2010-2012 Chevrolet Chevy 4-cylinder 1.6L and a wide range of Chevrolet, Buick, Oldsmobile, Pontiac, GMC and Isuzu models. This listing is one sensor, and the 2000-2004 Chevrolet Impala V6 3.4L takes one.

Frequently Asked Questions
Is this a Chevy oxygen sensor for the 2010-2012 Chevrolet Chevy 4-cylinder 1.6L?
Yes. Walker Products 350-34076 is listed for the 2010-2012 Chevrolet Chevy 4-cylinder 1.6L and for many other models. Use the "Vehicles it fits" section to check your own car.
Does the Walker Products oxygen sensor have platinum electrodes?
Yes. The electrodes of the 350-34076 are made of a gas-permeable platinum layer, and a coating protects the electrode surfaces from combustion residue and particulates.
How many wires does this narrow-band oxygen sensor have?
This sensor has four wires and is a narrow-band design.
What does this oxygen sensor report to the engine computer?
It determines the oxygen content of the exhaust gas and monitors the air fuel ratio, which gives the ECU feedback on combustion efficiency.
Does Walker Products 350-34076 interchange with CTK-OSGM4004?
Yes. CTK-OSGM4004 is listed as an interchange number for Walker Products 350-34076.
