• Monitors exhaust gases and reduces pollutants
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
• Electrodes are coated with a gas-permeable platinum layer
• Measures oxygen levels so the air-fuel mixture can be fine-tuned, which helps fuel economy

A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is the problem, since an exhaust leak, for example, can also throw off the readings. With the engine off, look over the wiring harness and connector for physical damage too.
