• Electrodes made of a gas-permeable platinum layer
• Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
• Measures oxygen levels to fine-tune the air-fuel mixture and support normal fuel economy
• Monitors exhaust gases to help reduce pollutants
• Narrow-band sensor with a 4-wire connection and flange mount
