Walker Products 350-34262 oxygen sensor for the 2009-2011 Chevrolet Aveo 4-cylinder 1.6L and other vehicles measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor is a direct-fit, 4-wire, narrow-band unit for the upstream position.
- Air-fuel ratio monitoring for combustion efficiency
- Electrodes made of a gas-permeable platinum layer
- Oxygen readings used to fine-tune the air-fuel mixture, which helps fuel economy
- Coating that protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Exhaust gas monitoring that helps reduce pollutants
Quick facts
- Part: Walker Products 350-34262 oxygen sensor
- Fits: 2009-2011 Chevrolet Aveo 4-cylinder 1.6L and other vehicles
- Position: Upstream
- Condition: New
Rough running, higher fuel use, more exhaust emissions or a check engine light can mean the sensor has failed, but other faults can produce the same signs. Before replacing it, look over the sensor, wiring harness and connector for physical damage with the engine off and cool, and leave any running tests to a shop.
Fits
The 2009-2011 Chevrolet Aveo5 4-cylinder 1.6L and the 2009-2010 Pontiac G3 4-cylinder 1.6L take this sensor, along with more vehicles. The 2009-2011 Chevrolet Aveo 4-cylinder 1.6L takes one, and this listing is one sensor. If your car is not named here, look up its year and engine under the "Vehicles it fits" section.

Frequently Asked Questions
Is this Aveo oxygen sensor right for a 2009-2011 Chevrolet Aveo 4-cylinder 1.6L?
Yes. Walker Products 350-34262 is listed for the 2009-2011 Chevrolet Aveo 4-cylinder 1.6L, and that engine takes one sensor.
Is the Walker Products 350-34262 an upstream or downstream sensor?
Upstream. Walker Products 350-34262 is a 4-wire, narrow-band oxygen sensor made for the upstream position.
Will a failed oxygen sensor set a fault code?
Newer vehicles store fault codes in the ECU, and some of them relate to the affected sensor and its associated systems. A shop can read the stored codes.
What does the platinum layer on this oxygen sensor do?
The electrodes are made of a gas-permeable platinum layer. A coating protects their surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases.
Does this oxygen sensor help with exhaust emissions?
Yes. Walker Products 350-34262 monitors exhaust gases to help reduce pollutants, and its oxygen readings let the air-fuel mixture be fine-tuned.
