The code P0404 on a Pontiac Aztec indicates a problem with the Exhaust Gas Recirculation (EGR) system, specifically that the EGR flow is insufficient. This can be caused by a faulty EGR valve, clogged passages, or issues with the vacuum lines. Addressing this code typically involves inspecting the EGR system for blockages or failures and replacing any defective components to ensure proper engine performance and emissions control.
