Car Emissions Testing & Repair Services Toronto & Etobicoke

British Columbia and Ontario have province-wide emissions testing that help keep air clean. Vehicle owners must pass an inspection if they want to continue driving their cars. Any vehicle that doesn’t pass the emissions test must get repairs.

Unfortunately, some common problems can make it impossible for vehicles to pass emissions testing. When your car fails, take it to an experienced mechanic who can diagnose and fix the problem.

Faulty Oxygen Sensors

Oxygen sensors measure the amount of oxygen present in car exhaust. When they don’t work properly, your car can’t make necessary adjustments. Without that ability, your car will fail its emissions test.

Mechanics have to replace faulty oxygen sensors so cars can pass their tests. Since this is a very common problem, it’s usually one of the first things that they look for after a car fails.

Damaged Evaporative Emission Control Systems

Evaporative emission control systems (EMCS) stop gas fumes from entering the atmosphere through vehicle emissions. An EMCS can fail for several reasons. When mechanics suspect this problem, they usually look at the:

  • Gas cap
  • Purge valves
  • Vacuum hoses
  • Vacuum vents

Any of these devices can prevent the EMCS from doing its job.

Malfunctioning Air Injection Systems

Air injection systems reduce harmful emissions (most notably carbon monoxide and hydrocarbons) by injecting air into the engine exhaust. When the system malfunctions, your car can’t regulate oxygen properly.

When mechanics find high levels of carbon monoxide and hydrocarbons in emissions, they often look at the air injection system to make sure it works well.

Vacuum Leaks

Vacuum leaks will also cause a vehicle to fail an emissions test. Experienced mechanics who suspect vacuum leaks typically start by looking at the MAP sensor. Without a functioning MAP sensor, the car cannot control its internal combustion. They will also look for common places where leaks occur. This includes gaskets and vacuum lines. Any of them could cause a vacuum leak.

Faulty Ignition System

Faulty ignition systems often occur in vehicles that don’t receive regular maintenance. Something as simple as a defective spark plug wire could affect your car’s ignition system. Since that’s an easy fix, many mechanics will look there first. If that isn’t the problem, then mechanics move on to inspect the distributor cap and ignition timing.

Getting your vehicle serviced by an experienced mechanic should help you pass your emissions test while helping you make your community a cleaner, safer place to live.
