Thanks much for the help and tips!

check the PDFD sensor on ford.
a quick easy test is to apply vaccum into the egr and see if the engine reacts. if it does then ur looking at something not activating the valve (solenod or vaccum lines) in case it dosent the ur looking at eather the valve or the passages ways on the egr.
let me know how it goes
good luck

hello,
I replaced the egr valve as well, but the p0401 code still comes on. I guess i have to clean the intake manifold and we'll see what happens. Thanks for the tip!

i have a 2004 chevy impala and I have that code, I bought a new EGR Valve and the code remains so I clean the intake manifold right?

ALWAYS CLEAN THE EGR PASSAGES first before replacing anything
