Walker Products 350-35128 oxygen sensor for the 2016-2019 Ford Explorer V6 3.5L and other vehicles measures the oxygen left in the exhaust gas. The engine computer uses that reading to monitor combustion efficiency and the air-fuel ratio.

• Five-wire wide-band design
• Made for a specific application and position on the vehicle, with the diagnostic feedback the ECU requires
• Electrodes made of a gas-permeable platinum layer
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
• Measures oxygen levels so the air-fuel ratio can be fine-tuned, which supports fuel economy
• Monitors exhaust gases to help reduce pollutants
