Only the California ecu needs to be fooled with a resistor.
There is no CA ECU for our cars, they're all the same.
All have the potential for the EGR code.
The CA spec cars have a temp sender in the EGR valve.
All other cars have a resistor in the connector for the temp sender.

Sorry to reply to an old thread, but what do you do to the VSV?
You leave it unplugged and let it dangle? Will it throw any codes
if I leave it unplugged?

if your car was originally from california, then it will leave a code. if not, then no. there is a way to get rid of the code (say if your car WAS from cali) but i am unsure how to do it. i know i read it somewhere on here though.
Just to clarify, and hopefully help at least someone understand better, unplugging the EGR VSV wont' automatically cause an EGR code.
The code comes from the temp sender mentioned above.
Unplugging the VSV [without removing any of the EGR stuff], will cause the code in a CA spec car, because the temp sender won't see high temps.
However, removing all the EGR stuff and leaving that VSV plugged in will also cause the code on a CA spec car.
On a non CA spec car you won't get a code unless you remove the resistor from the connector, or the resistor goes bad.
