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

A worn sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Those signs do not prove the sensor is the problem, because a vacuum leak can also produce rough running. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage.
