Vehicle Systems Overview - Emissions System


Your car’s emission system keeps the engine running cleanly and efficiently in all sorts of operating conditions. A steady or flashing warning light on your vehicle dashboard indicates a problem that is currently happening and may require immediate attention. Failure to do so can reduce your fuel efficiency and cause your vehicle to pollute.


Your car’s emission system controls the emissions of exhaust and pollutants (including gasoline vapours escaping from the fuel tank), using an array of sensors, computerized engine controls and the exhaust components. The emission system substantially reduces the production of harmful gases such as carbon monoxide (CO), unburned hydrocarbons (HC) and oxides of nitrogen (NOx) and, by law, must be maintained in operating condition.





Some factors affecting the emission system include:

  • Driving and atmospheric conditions
  • Mileage
  • Vehicle age
  • Type of spark plug electrode material
  • Poor vehicle maintenance 
  • Poor quality fuel
  • Damaged or worn sensors


  • Overly noisy engine​
  • Decreased power and acceleration
  • Decreased fuel efficiency
  • Burning smell from the engine
  • Hanging exhaust pipe
  • Gasoline smell
