Walker Products Oxygen Sensor P/N:350-35016
Walker Products 350-341047 oxygen sensor for the 2016-2017 Chevrolet LCF 3500 V8 6.0L and other vehicles measures the oxygen in the exhaust gas. This downstream sensor gauges combustion efficiency from that oxygen level.
A failing oxygen sensor can show up as a poorly running engine, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, though other faults can look alike. Before replacing it, look over the sensor, wiring harness and connector for physical damage with the engine off and cool.
This listing is one sensor. It fits the 2013-2016 Buick Verano 4-cylinder 2.0L and the 2011-2013 Buick Regal 4-cylinder 2.0L, which take one each, and the 2016-2017 Chevrolet LCF 3500 V8 6.0L, which takes two.
Fit and size
Build and materials
Is this the oxygen sensor for a 2011-2013 Buick Regal 4-cylinder 2.0L?
Yes. Walker Products 350-341047 is a downstream oxygen sensor for the 2011-2013 Buick Regal 4-cylinder 2.0L, and that car takes one. This listing is a single sensor.
Is this Walker Products oxygen sensor upstream or downstream?
Walker Products 350-341047 is a downstream oxygen sensor. It is a narrow-band, direct-fit design.
What thread size does this oxygen sensor have?
The thread on this downstream sensor is M18 - 1.5, and the sensor has four wires.
Could a lit check-engine light and poor fuel economy mean the oxygen sensor needs replacing?
They can, along with a poorly running engine or higher emissions, but other faults can look alike. A shop can read the stored fault codes to narrow it down.
What is the coating on this oxygen sensor's electrodes for?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes carry a gas-permeable platinum layer.
