Question about 2000 Honda Accord
Check engine light "ON"
took to auto zone error P0401
replaced EGR valve
light still on
-after you change the part you have to reset/clear the code
-this can be done by either:
(1) using the OBD2 code reader that Autozone used OR since option 2 (below) is very quick
(2) disconnecting the battery for about 30 seconds (this will delete all codes/radio presets/etc) but it will also clear the 'check engine' code
-this is what I do AFTER i write down my radio station presets :)
-hopefully the new EGR valve resolves your issue after you CLEAR the code
...but that code just means a an insufficient amount of Exhaust Gas recirculation (pressure difference) used to keep the emissions in check
-if it comes back, then there are a few other fixes to try also
-let me know if you need further assistance
-please remember to rate me `fix-ya`if it works

I had the same problem but only had to replace the PCV valve and then pull the fuse for the clock out and replace after 30 Seconds. The light has not come back on after 2 days of driving.

Here is a picture of where the EGR Valve is located. Replacing it is fairly simple and straightforward. A vacuum line and a couple of bolts. You'll see what you have to do when you look at it.
If you are replacing the EGR Valve due to the Check Engine Light (MIL) being on with a DTC P0401 then I suggest contacting your Honda Dealer. There was a Product Update Campaign (PUD) in the fall of 1999 that corrected the problem.
Thanks. keep updated for any more query.you can rate this solution and show your appreciation.
