Your car’s emission system controls the emissions, exhaust and pollutants using an array of sensors, computerized engine controls and the exhaust components. The emission system substantially reduces harmful gases such as carbon monoxide (CO), unburned hydrocarbons (HC) and oxides of nitrogen (NOx), and prevents harmful gasoline vapors from escaping at the fuel tank.
Typical Wear and Tear
Some factors affecting the emission system include:
• Driving and atmospheric conditions
• Mileage
• Vehicle age
• Type of spark plug electrode material
• Maintenance history
• Poor spark
• Bad fuel
• Damaged or worn sensor
