Walker Products Oxygen Sensor P/N:350-34340
Walker Products 350-34187 oxygen sensor for the 2022-2024 Chevrolet Groove and other vehicles measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor is a 4-wire, narrow-band, direct-fit unit.
A rough-running engine, higher fuel consumption or a lit malfunction indicator light can mean the sensor is worn, though damage to the wiring harness or connector can be behind those signs too, so look both over for damage before you replace the sensor.
The vehicles it fits include the 2022-2024 Chevrolet Groove, the 2019-2023 Chevrolet Aveo and the 2022-2023 Chevrolet Tornado Van, as a direct-fit replacement. If yours is a different car, look up its year and model in the "Vehicles it fits" section. This listing is one sensor, and one is called for per vehicle.

Is this Aveo oxygen sensor the right one for the 2019-2023 Chevrolet Aveo?
Yes. Walker Products 350-34187 is listed for the 2019-2023 Chevrolet Aveo, and the fitment calls for one sensor per vehicle.
How many wires does the Walker Products 350-34187 oxygen sensor have?
Walker Products 350-34187 has four wires and is a narrow-band design. It has an M18 - 1.5 thread.
Is the 350-34187 oxygen sensor an upstream or downstream sensor?
350-34187 is listed for both upstream and downstream positions. Which one it takes depends on the vehicle it goes on.
What does the platinum layer on this oxygen sensor do?
The electrodes are made of a gas-permeable platinum layer. The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas.
Can a failing oxygen sensor store a fault code?
Yes. Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems.
