Will Not High Idle For Warm Up

[PsYcO's ThErApY]

A friend of mine has an 01 7.3. He said the truck starts fine but when it tries to idle up for warm up it will only stay at high idle for a couple seconds. Any ideas

[Deeslfxr]

I would scan for codes. Not knowing anything about the truck, like how many miles, what mods are on it if any, what tranny, etc... makes it hard to diagnose.

He isn't touching the brake or revving it at all is he? Cause that does shut it off.........

Some have said if the emergency brake isnt on it will not high idle. Its not the case for my rig but I have heard it.

I noticed that mine stopped idling up after I put my DIY intake on. Someone suggested that there is a temp sensor that didn't get plugged back in

Well I'm thinking that depends on if it's a manual or not. Mine's an auto. So it has to be in park, foot off the brake. I say it has to be in park (not being captain obvious) there's a "park validation switch" in the column tied into the wiring harness on the top somewhere. That has to be working too lol

Yeah it should be hangin around there somewhere lol. It looks like a probe, like an inch long tiny delicate lookin thing.

Is theres something in my stock intake that I need to take out and plug that sensor back into If so, where should I mount it?

Just make sure the sensor itself is plugged in and then ziptied anywhere in the general vicinity.
