• Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
• Electrodes with a gas-permeable platinum layer
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and exhaust particulates
• Monitors exhaust gases to help reduce pollutants
