What Specific Emissions Exceed Standards Due to Oxygen Sensor Failures in Vehicles?
Oxygen sensor failures can lead to various emission pollutants exceeding standards, primarily including the following three major pollutants: Increased Carbon Monoxide (CO) Emissions When the oxygen sensor fails and causes a rich mixture, a large amount of carbon monoxide is produced. Under normal circumstances, the oxygen sensor accurately controls the air-fuel ratio around the theoretical … Read more
