A code P0401 most likely means one or more of the following has happened:

The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
There is a blockage in the EGR (tube), most likely carbon buildup
The EGR valve is faulty
The EGR valve may not be opening due to a lack of vaccuum

Thanks for your reply. Unfortunately, the 2004 CRV has no EGR. Per the previous person's advice, I asked Scotty Kilmer and he thinks it's probably some kind of software issue and that I should see the dealer...

Thanks again.
Go to youtube and look up scotty Kilmore (not sure if spelled correctly but it will come up)
Thanks! I've posted this question on three car repair forums and you're the only one to reply. I'm looking over scotty kilmer's videos right now.
