• 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
• Measures oxygen levels so the air-fuel ratio can be fine-tuned, supporting fuel economy
• Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
• Monitors exhaust gases to help reduce pollutants
