A while ago i had all the main engine seals replaced and shortly after getting it back my check engine light came on so i took it to advance autoparts and it was the p0401 code for insufficient egr flow.
Finally today I got around to looking into it and took the plastic cover off and just about immediately I noticed a wire that was just not connected.
You can see in the picture below the orange connector that is just hanging
loose which is how i found it. So I just plugged it in and reset the battery to clear the code.
The only thing is I don't really know much about it but looking at old threads and pictures it looks like it could be the connector for the VSV part of the egr system? It's on a 2000 V6 Camry. If anyone could tell me what exactly it was that failed to get plugged back in from the shop and if that's probably why the egr code popped up that would be awesome. Thanks.
