It is made for its specific application and fitment position, and gives the ECU the diagnostic feedback it needs.

• Oxygen readings help fine-tune the air-fuel mixture, which supports fuel economy
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
• Monitors exhaust gases to help reduce pollutants
• Electrodes with a gas-permeable platinum layer
• Narrow-band sensor with 3 wires

A failing sensor can make the engine run poorly, raise fuel use or exhaust emissions, or turn on the check engine light. Those signs alone do not prove the sensor is at fault, since a damaged wiring harness or connector can produce them too.
