Good Brakes Automotive Performs ADEO Emission Testing & Repairs

Most Common Problems
There are many components that if not working properly can result in high emission levels on vehicles. Basically, they are designed to keep pollution down and the emissions released low. When an emissions component fails, it can cause the car to have driveability problems or produce and release high levels of pollution. Emission testing is performed to keep vehicle emissions down and to avoid causing health problems. Some components of the Emissions System are:

  • Spark Plugs
  • Spark Plug Wires
  • Distributor Cap/Rotor
  • Air Filter
  • PCV Valve
  • Fuel Filter
  • Catalytic Converter
  • EGR Valve
  • Air Pump
  • Oxygen Sensors

Emissions tests detect high levels of Hydrocarbons, Carbon Monoxide and Nitrogen. Such results may cause you to fail your state's Emissions test. Usually, if the car is well-maintained these components last a long time. State governments and Federal government agencies place limits on Emission standards, and they may change each year according to vehicle, and vary from state to state.

Emissions Testing may be a complicated process. Some of the tools and equipment necessary can be expensive, and a trained professional will be required to determine the correct diagnosis. Emissions sniff machines, smog machines, and Dyno machines are used to test five different exhaust gases during a simulated drive course. Some other pieces of equipment that may be used are Scanners, Digital Voltmeter, Lab Scopes, Compression Tester, % Gas Analyzers, and may be costly to a technician that doesn't specialize in Emissions Testing & Repair. If the "Check Engine" or "Service Engine Soon" indicator illuminates, your vehicle should be serviced by a qualified technician right away. Possible causes of this indicator lamp are as follows:
  • Oxygen Sensor
  • Catalytic Converter
  • Oil Contaminated Spark Plugs
  • Air Injection System
  • Air Filter
  • Vacuum leak
  • Intake Leak
  • Bad MAP Sensor
  • Fuel Injectors
  • Fuel Evaporation System

Hydrocarbon Failure is the result of incomplete combustion. Any item that causes incomplete combustion can result in high levels of Hydrocarbons. The most common causes are:
  • Worn Spark Plugs
  • Worn Distributor Cap and/or Rotor
  • Jumped Ignition Timing or Timing Belt
  • Vacuum Leaks
  • Engine mechanical failure, low compression
  • Valves burn or leak

Nitrogen Oxide Failure is the result of combustion temperatures that are too high. The most common causes are:
  • Bad Exhaust Gas Re-Circulation Valve
  • Timing
  • Excessively Rich or Lean Mixtures
  • Clogged Fuel Injectors
  • Defective Oxygen Sensors
  • MAP Sensor
  • Airflow Sensor
  • Intake Temperature Sensor
  • Restricted Radiator
  • Defective Thermostat
  • Defective Electric Thermostat
