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: HC Failure is the result of incomplete combustion. Any item that causes incomplete combustion can result in high HC.
How can I diagnose high emissions in my car?
DIAGNOSISDiagnosis of high emissions can be an involved process that usually requires special tools and measuring equipment.
