Description：
The oxygen sensor, located either upstream or downstream of the catalytic converter, is designed to monitor the air-fuel mixture under idle, moderate acceleration, and cruise conditions. Symptoms of a faulty or bad oxygen sensor include bad gas mileage, rough idle, reduced drivability, and an illuminated check-engine light.
