Failed Emission Repair For Illinois: Palatine IL 60067 | Arlington Heights IL 60004 | Streamwood IL 60107

Failed emission repair involves the diagnosis of high emissions and can be an involved process that usually requires special tools and measuring equipment. However, Casey Automotive can produce test reports indicating what gases are high can help you determine what systems may not be functional. If the vehicle has failed as a result of high CO and HC, the CO failure should be diagnosed first. If the “Service Engine Soon” or “Check Engine” light is on it should be diagnosed prior to any emissions diagnosis. CO Failure is the result of an excessively rich air fuel mixture. The following is a list of the most common causes:
- Defective Oxygen Sensor
- Inoperative Air Injection System (if equipped)
- Leaking or defective Fuel Injectors
- Restricted air filter (especially if high CO is present only at high RPM)

- Malfunctioning fuel evaporation system or purge valve
- Defective Catalytic Converter
- Defective thermostat (cooling system), thermostat stuck open
