• Tracks the air-fuel ratio to show combustion efficiency
• Electrodes made of a gas-permeable platinum layer
• Helps fine-tune the air-fuel mixture to support fuel economy
• Monitors exhaust gases to help reduce pollutants
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust
