is my ebpv is sticking?

[WYO_7.3Powerstroke]

well it finally got cold in SE WY this mornin, started the truck this mornin let run about 10 min hopped in it and drove it, it was really doggy and black smokin, then after the needle rose above the C mark it would go then get really doggy and have a almost boost leak noise then it that noise would go a way and truck would go again buildin boost. but if i was just cruising it would go back and forth between the "boost leak noise" then to the runnin normal, and as soon as it got to operating temp it quite fluctuating. im pretty new to the powerstroke as a daily driver (drove my fathers a few times before i purchased mine) so idk if that "butterfly valve" is stickin or if it just fluctuates until its at operating temp. also my temp needle only goes to like between the N and O so idk if i need to replace my thermostat or not. any help is appreciated. thank you.

Sounds like your ebpv is working to me it will open and close until the engine is up to temp

will it fluctuate while driving? thanks

[erics diesel]

yes that is why most people put it on a switch or just delete it altogether

oh alright thanks i appreciate it just want to keep up on it dont want nothin to break im on a college budget lol. where does ur temp gauge run im not sure if i should replace mine or not only runs on the N and sometimes between the N and O on normal but when im huntin and idling it drops below the N not sure if my thermostat is stuck open or what not. thanks

Mine rarely ever gets above the N in normal... both of my 97's were the same way.

these trucks have a massive cooling system. mine has never gone above the N O area

If you're looking for a quick fix, just unplug the EBPV solenoid. There is a plug under the turbo, on the turbo pedistal, accesible from the drivers side. Disconecting it will cause a 'soft' code, but there will be no CEL. Chances are if the EBPV is malfunctioning, it is probably already throwing the cod .
As far as the temperature these trucks have a dummy gauge, meaning the position of the needle does not actually reflect the engine temperature. If the guage is all the way to the left, it means the truck is below operating temperature., anything in the middle means the engine is at operating temperature, and the red signifies above operating temperature. The guage may wander during driving, but there are only three distinct inputs given to the guage by the PCM.

If you have a block heater installed you can plug that in at night and completely remove the EBPV with out a problem. Or just plug it in every night as the weather gets cooler and won't have the EVPV doing the "shutter" effect on you while driving around.
