Walker Products 350-34321 oxygen sensor for the 2018-2021 Chevrolet Beat 4-cylinder 1.2L and other vehicles reads the oxygen content of the exhaust gas. This narrow-band sensor works in the downstream position and gives the ECU the diagnostic feedback it needs.
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Monitors exhaust gases to help reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Electrode coating guards the electrode surfaces against contamination and erosion from combustion residue and exhaust particulates
- Narrow-band sensor with 4 wires
Quick facts
- Part: Walker Products 350-34321 oxygen sensor
- Fits: 2018-2021 Chevrolet Beat 4-cylinder 1.2L and other vehicles
- Position: Downstream
- Condition: New
A failing sensor can show up as a poorly running engine, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. The wiring harness and connector can be behind those signs too, so look both over for damage once the engine is cool, and find the cause before you buy a sensor.
Fits
This sensor is listed for a wide range of Chevrolet and Pontiac models, among them the 2018-2021 Chevrolet Beat 4-cylinder 1.2L and the 2009-2011 Chevrolet Aveo 4-cylinder 1.6L. The 2018-2021 Chevrolet Beat 4-cylinder 1.2L takes one downstream sensor, and this listing is a single sensor. If your car is not named here, run its year and engine through 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 350-34321 is listed for the 2009-2011 Chevrolet Aveo 4-cylinder 1.6L as a downstream sensor, and that engine takes one.
Can I use this oxygen sensor on a 2018-2021 Chevrolet Beat 4-cylinder 1.2L?
Yes. The 2018-2021 Chevrolet Beat 4-cylinder 1.2L is in the fitment for this downstream sensor and takes one.
What does this narrow-band oxygen sensor measure?
Walker Products 350-34321 measures the oxygen content of the exhaust gas and watches the air-fuel ratio for combustion efficiency. It has 4 wires and an M18 - 1.5 thread.
Can a failing oxygen sensor like this one light the malfunction indicator?
Yes, it can. A failing sensor can also show up as a poorly running engine or higher fuel consumption and exhaust emissions, and newer vehicles store fault codes in the ECU.
Does this sensor replace CTK-OSGM4025?
Yes. Walker Products 350-34321 is listed as a replacement for CTK-OSGM4025.
