EGR valve - where at on I30?

[absintheminded]

Got the dreaded P0400 today. Looking for the EGR valve and, uh, not having much luck.

Where the heck is it? Does someone maybe have the FSM page?

Thanks in advance!

Oh, it's a 1999 model, btw

Welcome to NICO! You've come to the right place for your questions.

As for the dreaded Po400, it's not as bad as you think. Approximately 90% of the time it is not an EGR failure, but rather the EGR guide tube hasd become blocked with carbon buildup. The guide tube is an easy fix requiring you to remove only 4 bolts. one is not so easy to get to but it is a much cheaper fix than replacing the EGR itself. Unfortunately, I do not have access to this particular FSM, but if you go to your local parts stores and purchase the Haynes manual for your particular vehicle and they'll give you full illustrations on where the EGR guide tube is.

http://www.phatg20.net you can get the FSM there in PDF format, i just want to know how to eliminate the EGR, is the EGR temp sensor the only thing that throws the P0400 code?

yes the egr temp sensor is the main diag tool the ecm uses during egr function. by looking for a drop in voltage the ecm is able to determine flow of the erg valve.
