You can clear the code using a code reader. If you don't have one, an auto shop can clear it for you. They may charge you. The code may go away on it's own if it was fixed properly, and the ecu reads the egr system is functioning properly again.
Don't assume that a code that is related to the EGR system is necessarily the EGR Valve at fault.
egr was not installed until 2005 on this particular engine.
Trouble code P0401 means: EGR System Malfunction Replace the EGR Valve
Egr code
I would double check that that is the actual code stored in the PCM. That is a code for EGR and you are correct that you do not have EGR.
EGR system failure. The EGR valve has failed.
It is a code for a failed EGR valve.
where'sthe egr flow on a 2000 ford expedetion {code; P0401
No,Its has to do with the EGR valve
Plugged egr tube or a failed egr valve.
Could be an EGR port clogged with carbon. Remove and clean EGR and EGR ports.
Did you delete the code? After you fix the problem you have to connect the computer back and delete the code. If you dont the code will still pop up
