EBPV Activating while driving
Well as the title says this morning I warmed the truck up for about 15 minutes then shut it off (had a delay in the trip) started her back up about an hr later she was still a bit warm and drove here a few miles down the road the dummy gauge showed it was warm but while in the throttle the EBPV would activate then shut off activate then shut off. No matter how hard I was in the throttle. I am about to leave back out in a few minutes for a 50 mile trip I'll see if it does it anymore. I also have noticed some mornings on warm up the EPBV will start then deactivate about half way through the high idle or it will shut and the high idle will kick out. Keep in mind I always start my truck in stock.
I have a nearly new EBPV on the way soon maybe that will fix it.

Yep, and that's what a lot of guys do. I'm considering it also but haven't got around to it yet.
JD, mine was doing the same thing last spring on me so I unplugged it. Ran for a while and decided to give it another chance, then it decided to start flapping shut on decel so I unplugged it and it has stayed that way. I would just unplug the bugger and forget about it.

Hook it, I'll pull it.

I Have not heard my EBPV work yet this winter. I keep the truck in the shop all the time now, so that might have something to do with it, besides not being very cold, besides this morning 33*.
I didn't think it would close while going down the road thou.

If its cold enough out, the thing will close constanly while driving. Its been in the low teens here at night (and days now too) and driving around with the heater going and the fan on the 3rd setting cools the engine off enough to kick the EBPV on. Turning it down a click keeps the engine up to temp and the EBPV off.

Sounds like normal operation to me. Mine does the same thing till the engine is good and warm, no matter what speed I'm going...

I could warm the truck for 5 min. drive away with the EBPV closed and it wont open no matter what till the tranny warms up enough to lock the TC. I do have the EBPV brake on a switch with the red hot wire going to the switch on another switch. Then I can turn the EBPV off only when the ecu trys to keep it on. Haven't tryed it yet so thats how I hope it will work.
Would manuly locking the tranny when cold hurt anything if I am not hammering on it?

If you want to make an exaust brake out of it, what I did, basically that's what you do. Look up the EBPV mod.

I ditched mine when I put in the van turbo & don't miss it. Even when I start it after a cold day at work like today, it's not a big deal. Anyone with an aftermarket or van turbo doesn't have an EBPV either, and I've never heard of it being an issue. It sounds kind of cool, but it's a PITA sometimes. My $0.04 (inflation).

I have not had to do this myself yet, but maybe your EBPV is a bit clogged up. This may help.

Possibly. The fluid might not be warm enough to fully lock the t/c. I know locking it below 1200 rpms is frowned upon because the pressure is too low to hold the clutches from slipping.
