Dirtymilkman Posted December 25, 2017 Share Posted December 25, 2017 My Titan lost all of it's boost today. It worked this morning and it eventually got worse. Once in awhile I'll get 7 psi. 0 psi while engine breaking. Exhaust temp does climb till I let off. No whistles or leaking sounds. Boost will rarely climb to 15 psi but only on a hill. Running down highway at 55 boost is 0. At idle it's 1 psi. Actuator? Turbo? I figure it can't be a boot I'd hear a leak.

fjh Posted December 26, 2017 Share Posted December 26, 2017 (edited) Possibly the egr valve is stuck open or turbo stuck try giving the valve a tap Edited December 26, 2017 by fjh 1 Quote Link to comment https://www.bigmacktrucks.com/topic/52044-mp10-lost-boost-completely/#findComment-388230 Share on other sites More sharing options...
Mackpro Posted December 26, 2017 Share Posted December 26, 2017 I would say turbo actuator/vanes sticking , which should set a code. Or boost pressure sensor which won't set a code.

Dirtymilkman Posted December 29, 2017 Author Share Posted December 29, 2017 Nox sensor supposedly. We'll see when it gets below zero again. Quote Link to comment https://www.bigmacktrucks.com/topic/52044-mp10-lost-boost-completely/#findComment-388442 Share on other sites More sharing options...
Dirtymilkman Posted December 29, 2017 Author Share Posted December 29, 2017 Well, it's not the nox sensor. Still acting up today Quote Link to comment https://www.bigmacktrucks.com/topic/52044-mp10-lost-boost-completely/#findComment-388482 Share on other sites More sharing options...
41180 Posted December 29, 2017 Share Posted December 29, 2017 Turbo actuator or egr . Is it building exhaust temp if you rev it up Quote Link to comment https://www.bigmacktrucks.com/topic/52044-mp10-lost-boost-completely/#findComment-388494 Share on other sites More sharing options...
41180 Posted December 29, 2017 Share Posted December 29, 2017 Mine had a actuator go but I couldn't even drive the truck our of the yard. Certainly it wouldn't do 55. My egr valve stuck open and boost was all over the map.

Dirtymilkman Posted December 29, 2017 Author Share Posted December 29, 2017 This is only doing it when it gets below zero and after it's been running awhile. They said actuator is nice and smooth and vanes turn easy. Next is pull turbo and egr off.

Actually the EGR valve check ain't to bad IF that's what it is! $130 an hour and these technicians walk around like they're sleeping. For that kind of money they should be running to the parts counter and back. You go in the shops and see a whole new level of putz. The day crew isn't bad, but the night crew is horrible.

fjh Posted December 31, 2017 Share Posted December 31, 2017 (edited) Unfortunately in this instance and in most instances These days the computer has slowed everything down it heeds time to update it needs time to think! so you don't get the chance to run back and forth just stand and watch! You supervise it ,so it can supervise you! Let us know what computer finds!

41chevy Posted December 31, 2017 Share Posted December 31, 2017 I see some of the time that the techs rely on the computer for all the answers and unfortunately many forget to look at the basics.

Dirtymilkman Posted January 3, 2018 Author Share Posted January 3, 2018 I would love to know the verdict too. Being a milk truck, this truck is very hard to lay up for exploratory surgery. It goes in tomorrow evening, maybe we'll find out more.
