I'm getting the Check Engine Light and Autozone showed me error
P0401.Does anyone have a link or something that describes the process
on how to clean the ports and hoses and also showing the exact
locations of all the parts.I tried online to find the locations of
intake manifolds and all these things that some have posted about but I
can't find them
Any help is greatly appreciated.
Thanks in advance.

is it a 4 or 6 cylinder?

It's the 4cyl VTEC engine

Well, there's only one intake manifold (the silverish manifold) so no
need for plural. The intake manifold is closest to the firewall
(opposite the exhaust manifold on the cylinder head). To clean the EGR
you typically either need to remove the EGR valve and spray and scrape
it clear with some throttle body cleaner (or
carbuerator cleaner). Occasionally the intake manifold ports need
cleaning. Search the groups for EGR cleaning. This typically involves
drilling 3/8ths inch or so hole in the EGR runners in the intake
manifold and cleaning them with a wire brush. If you're not very
experienced or mechanically inclined, I'd recommend taking it to the
shop to get this done. Otherwise, locate the ports and do the cleaning
youself. The www.helm.com manual helps, but it won't tell you the
complete procedure, (just how to locate them). Cleaning them should be
common sense once you can see inside
