A code P0400 on a Geo Tracker indicates an issue with the Exhaust Gas Recirculation (EGR) system, typically related to flow problems. To fix this, start by inspecting the EGR valve for blockages or damage, and clean or replace it if necessary. Check the EGR passages and vacuum lines for any obstructions or leaks, and ensure the EGR control solenoid is functioning properly. After addressing these components, clear the code and test drive the vehicle to see if the issue persists.
