The secondary air injection pump injects fresh air into the exhaust stream to help burn off harmful pollutants in the catalytic converter. If the injection pump begins to fail, since it is a vital part of the emissions system, a fault code will be triggered. Sometimes, when pulling off the lower secondary air pipe, you may see water pour out. This is a sign that your pump is more than likely faulty. By simply replacing this pump, efficiency can be restored and there will be no worry about failing an emissions test.

If you’re dealing with emissions-related faults, the Secondary Air Injection (SAI) pump is an important component to check. This system is designed to inject fresh air into the exhaust manifold during cold starts, helping reduce harmful emissions while the catalytic converters warm up. When the SAI pump is damaged or not operating correctly, emissions can increase and fault codes may be triggered. In states that require emissions testing, a failed air pump can easily result in a failed inspection. Replacing a faulty Secondary Air Injection Pump helps restore proper emissions control, clear related fault codes, and ensure your vehicle remains compliant with emissions requirements.
