Hey everyone long time lurker first time poster.
I have a 1997 Geo Prizm with a 4AFE engine in it that's giving me the error code p0401
This engine appears to not have an EGR valve, VSV, or anything else installed though
Anyone come across something like this? It's possible the engine or many parts of it
are not original (this was done by family before I owned it) so i'm curious, do I try to buy the parts
and put it on? Or is this motor not equipped with EGR? If so how do I go about clearing the code?
Pictures of the engine and area in question below.
