Can anyone think of anything that may have been missed? I have been having the same problem and spent thousands of dollars and still have the same problem. Plug it back in and it should return to its normal position. I took it to my mechanic and it was just the air line going to the turbo actuator was rusted at the connection so their was not enough air to operate the actuator. This weekend I'm going to check that valve by the intake manifold. I kept having problems on the turbo side.

I hope they did not mess anything up there lol. And on my boost gauge Psi goes to 25 psi and down to 5 psi and rinse and repeat when you drive. Put on a fuel gauge. Just changed the Delta P sensor. . Just kept limping it in and it all came back then went away every different sequence u could imagine. They don't want to change the whole turbo.

Freightliner turbo boost cuts out

turbo actuator freightliner

I'm trying to find out when I'm driving why is my boost go up and down. If by chance you got yours fixed please let me kmow what it was I have spent thouands on this truck and no fix yet. The truck just feels very sluggish because there is no turbo kicking in. Also going to be installing new Cam shaft and Crankshaft sensors. Added a restriction to my return line. Several friends have mentioned it is a sensor but nobody seems to know the name of it.

I have a 2004 freightliner 60s detriot and have the same problem you have. Changed turbo actuator it did have a small leak. All sensors on intake manifold changed. Internal wastegates are set to handle stock power, and are usually swapped out for external wastegates to accommodate a bigger turbocharger or better control of boost and power output. Diversion of the exhaust gases is what controls the speed of the turbine that regulates the rotating speed of the compressor. Never heard somebody that had sucess changing actuator. Keep in mind you cannot yourself manually move the servo linkage because it is a worm gear drive.

It's a pain in the rear to calibrate the actuator with a existing turbo. Where the turbo cuts out blows black smoke chokes up coughs then snaps out of it. Some Freightliner shops do it specially if the truck is under warranty. Hi flatbed sorry for the late response. Recently the truck has lost power and feels like the turbo is not kicking in when accelerating.

Then I got in the vehicle stuck it in drive and rev'ed it up to around 2,000 rpm. When you start the motor and there is no air in the system. Psi on idle is 23ish, but when I'm driving its falling close to 0. Something cutting off the boost and then lets it boost up and cut off. If I put in the stock barometric sensor. But it looks like it did not cut off boost like it does with speed sensor plugged in. Same thing, cutting in and out.

How can my turbo actuator be repaired.

Pours it black smoke and heated up immediately. But did not solve it, went out for a test run bobtail. I would almost have to red line it for the turbo to kick in. I have had a prolem with my van since I bought it cutting out on hill climbs overboosting. Hello All, I have an 05 Century with the 14. Once tested, the actuator is completely disassembled and cleaned. If that will fix the issue I'm going to really pissed at shop that could not help me diagnose this.

Please see for details or just call. Engine revs smooth except at 1500 there is a small hiccup I can feel it. I just set up my laptop to connect to my truck. So tomorrow I will go buy a new turbo speed sensor and hopefully that will solve this issue. Everytime we go to put it on the computer, each mechanic tells us something different. It must be the check valve behind the motor. I will post up a youtube video when I get a chance.
