The air pump is an important part of your vehicle emissions control system. It is used to inject fresh air into the exhaust system to aid in the combustion of harmful pollutants in the catalytic converter.
If this air pump fails, fresh air will no longer be introduced into the exhaust system, drastically increasing the amount of pollutants coming from your vehicles exhaust. This can be exceptionally bad when it comes time to pass your states vehicle emissions test.
If you think that your air injection pump has failed, it must be replaced in order to keep your car running at its best.
