The P1404 code on a Pontiac Montana indicates a problem with the EGR (Exhaust Gas Recirculation) system, specifically related to the EGR valve. To fix this issue, first inspect the EGR valve for blockages or damage and clean or replace it if necessary. Additionally, check the vacuum lines and electrical connections for any leaks or faults. If the problem persists after these steps, consider diagnosing further with a scan tool to check for related issues in the EGR system.
