It is letting you know that there is an issue with the secondary air injection system. The secondary air injection system injects air into the exhaust to help lower emissions.

Why does my Chevy Trailblazer have a bad air pump?

Nearly all of the time, the only symptom of P0410 in the Trailblazer is going to be the service engine soon light. Otherwise, you may hear the bad pump trying to work (like an empty wiper/washer, usually more faint sounding). Vary rarely, it can cause some hesitation on acceleration. Typically, there are three main components to the AIR system.

Can a p0410 cause a Chevy Trailblazer to break down?

If they are no longer accepting instruction from the ECU, P0410 will be thrown. P0410 in the Chevy Trailblazer is not likely to cause the vehicle to break down, and rarely causes symptoms other than the check engine light. That’s because the pump is part of the emissions system and not the engine itself.

What is the OBD II fault code PO 410?

OBD II fault code PO 410 refers to a fault or defect in the Secondary Air System, also known as the Secondary Air Injection System, that is fitted to some vehicles. The purpose of the system is to inject atmospheric air into the exhaust system during cold starts to assist in the oxidization,…

What causes an air injection pump to fail?

The air injection pump system is to help lower the emissions coming out the exhaust and can cause the vehicle to fail emission testing. The check engine light being on causes the vehicle to fail emission testing. The air injection pump should not cause any drive symptoms other than a Check Engine Light.

When does the p0410 O2 sensor fail?

Code P0410 is triggered when the air injection pump passive test fails or is inconclusive then the ECM commands the pump to do an active test and the O2 sensor does not output a higher O2 content in the exhaust within 3 seconds. Need help with a P0410 code?
