Walker Products 350-34428 oxygen sensor for the 2008-2009 Chevrolet Equinox V6 3.6L and other vehicles measures exhaust oxygen to gauge combustion efficiency. This Walker Products oxygen sensor is made for its specific application and fitment position, and it sends the ECU the feedback it needs.
- Narrow-band, 4-wire direct-fit design
- Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gases
- Electrodes made of a gas-permeable platinum layer
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-34428 oxygen sensor
- Fits: 2008-2009 Chevrolet Equinox V6 3.6L and other vehicles
- Position: Upstream left, upstream right, upstream rear, upstream front
- Condition: New
A failing oxygen sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a check-engine light. A vacuum leak, for example, can also make an engine run poorly, so these signs alone don't prove the sensor is at fault. The sensor, wiring harness and connector should also be checked for physical damage.
Fits
This direct-fit oxygen sensor also suits the 2008-2011 Cadillac CTS V6 3.6L and the 2008-2011 Cadillac STS V6 3.6L. The listing is one sensor, and the application takes one. If your car isn't named here, look up its year, model and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right Chevy Equinox oxygen sensor replacement for a 2008-2009 Chevrolet Equinox V6 3.6L?
Yes. Walker Products 350-34428 is listed for the 2008-2009 Chevrolet Equinox V6 3.6L. For other vehicles, check the "Vehicles it fits" section.
Is the 350-34428 oxygen sensor right for the 2008-2011 Cadillac CTS V6 3.6L?
Yes. Walker Products 350-34428 is listed for the 2008-2011 Cadillac CTS V6 3.6L, and the 2008-2011 Cadillac STS V6 3.6L is listed too.
Is the Walker 350-34428 oxygen sensor narrow-band or wideband?
It is narrow-band. This sensor has four wires and an M18 - 1.5 thread.
Is the Walker 350-34428 an upstream or downstream oxygen sensor?
It is upstream. The positions are upstream left, upstream right, upstream rear and upstream front.
What does the coating on this oxygen sensor do?
The coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases. The electrodes are a gas-permeable platinum layer.
