There could be several reasons for a failed emissions test. A common reason is that the catalytic converter has failed. The catalytic converter removes some of the harmful elements in exhaust. When a catalytic converter fails it must be replaced. Many people stop there but the converter failed for a reason and there may be any number of engine run conditions that led to that failure. It is a good idea to have your technician diagnoses the cause so that you don’t end up with another catalytic converter replacement down the road.
If you smell exhaust in the passenger cabin or hear an unusual exhaust sound, get your exhaust system checked and repaired. Do NOT delay to have it checked out. It could be deadly! Carbon monoxide in your exhaust is odorless, colorless and tasteless. It can be fatal to you and your passengers. Do not delay if you suspect an exhaust leak.
