• Electrodes coated with a gas-permeable platinum layer
• Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
• Measures oxygen levels so the air-fuel mixture can be fine-tuned, supporting normal 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 gas
• Narrow-band design with four wires
