[sm=welcomesign.gif]Code P0402 Exhaust gas recirculation flow excessive detected.[hr]What it means is you have a fault in the EGR system.[hr]The most common fix for this. [hr]Replace the DPFE Sensor (EGR pressure sensor). [hr]Very common failure for EGR codes.

 

this is on a f150 2002 does that matter?

 

No, I could tell by the code the year range.
