warm up mode 97 powerstroke

[Jordanb]

i have some questions about the ebpv on my truck it is a 97 im tring to figure out all the sensors ect. what my truck does is ill let it warm up in the morning you can drive for a half hour then shut it off go to leave 2 min later and the valve is closed thats on a hot 80 degree day. what would cause that my wife has a 03 with the 7.3 and hers on a cold morning will start up then the valve will close and truck goes into high idle till warm is mine sopose to do that also? where should the temp gauge run at mine empty runs a little under n on the normal is that to cold?

Welcome to the forum!

Try cleaning the tube from the passenger side exhaust manifold to the sensor. It likes to plug with soot. I take off the tube (not hard) and use carb cleaner with wire rope chucked in a variable speed drill (like a plumbing snake) to clean it. Also clean the little tube left on the sensor and the sensor. That worked for me in the past. Cheers!
