Ford 6.0L Power Stroke Diesel :: 2005 - Code P0299 Under Boost Condition

I'm having a little trouble with my 05 Excursion 6.0L .... We took off camping the other day pulling our 30' camper and the engine light came on pretty much as soon as we hit the highways. I checked my Dash boss and it came up as P0299 under boost condition. The truck never skipped a beat. The boost gauge never dropped and it seemed to have lots of power. Actually I've noticed too much boost while pulling. It's climbed up to 36psi before and was still climbing when I backed off the throttle. I'm thinking the turbo is fine but not sure what to check next.

Ford 6.0L Power Stroke Diesel :: Air Leak / Slow Turbo Response / Code P0299

I am fairly new to working on diesel engines. I was towing a camp trailer and got a P0299, Turbo Charger Underboost engine code. I never gotten any other codes other than this one when towing. I decided to pull the turbo and clean the vanes. Everything seemed to go back together good but now I hear what sounds like an air leak coming from the turbo area. The boots on the intercooler pipe are in good shape, I only loosened the clamps at the intercooler and the turbo. Left the boots on the pipe. I have tightened the clamps around the exhaust pipe connections with no change. I also seem to get a slower response from the turbo and possibly not as much psi as normal (according to dashboard gauge). I have driven the truck five or ten miles trying to work the turbo and have not gotten any engine codes to this point.

Ford 6.0L Power Stroke Diesel :: Black Smoke / Low Boost / Loud Hiss - Code P0299

Last night when I was towing my son's Ranger home - somebody stole all his gas & he thought the fuel pump quit - heard a pop and the truck started running like crap. Thought I had blown the CAC boot loose but that wasn't the case. As it turns out, the tube for the EBP sensor came off from the manifold.

I had taken it loose about a year ago to clean it out. I guess I didn't tighten it well enough. Truck blew black smoke, lost boost, and filled the cab with exhaust fumes. Easy enough fix, kind of hard to diagnose because that's not expected. Just throwing it out the for somebody's future search.

Ford 6.7L Power Stroke Diesel :: 2013 - Turbo Noise - Loosing Boost Over And Over Again

I have a 2013 F350. Since it was new in August the turbo has made a chattering sound that sounds to me like the waste gate (if it had one) is opening and closing rapidly. Almost like its building boost and dumping it over and over again. Usually happens when it is in 6th gear around 1700 rpm under light load. It also does it from time to time while plowing snow. You can power through it or let off and it will go away. My local dealer where it was bought new put a new turbo on it and the problem still persists. The truck just turned over 8k miles and has been in several times in attempt to resolve the issue. They say that there are no codes on the truck nor does Ford have anything on their service web. My dealer claims that no one has ever had the issue.

Passat (B5) :: CEL Is On - Code P0299

The 1.8 passat turbo has 60k miles on it.

CEL is on, shop says it is code P0299 (I have read this code being called the "underboost" code). Local shop also wanted $1500++ to put on a new turbo. Car is driving and responding just fine.

I have searched high and low and can't find definitive answers to these questions.

I have read some posts indicating that replacing the Waste Gate Valve has improved performance and turned off the CEL. Can you replace this valve on the 1.8 without replacing the whole turbo?

Where is this valve in the engine compartment? Can I just clean it? CEL code 0299, car behaving normally, shop telling you that your need to replace the turbo?

Passat (B6) :: CEL On / Code P0299 - How To Replace The Diverter Valve

The CEL on my Passat came on. When I scanned it with VAG-COM, the following fault code was displayed:

000665 - Boost Pressure Regulation
P0299 - 002 - Control Range Not Reached

The car also felt like it lost its power in some way, especially when the turbo kicked in. So after some research, I found out that the Diverter Valve was causing this issue. Rubber diaphragm on original valve was made from rubber and was torn. I replaced it with upgraded valve and wow what a difference!!! Very easy to do, great write up link below.

Passat (B5) :: 1999 Turbo 1.8t / Extremely Low Boost

My passat turbo went out a while back and cant figure out why? The Idle is the same as always was, engine is smooth while driving and changing gears, but the boost is very very low but not completely out. All vaccum lines are connected and cant hear the diaphram releasing like it used to abviously cause there's no pressure.

Ford 6.0L Power Stroke Diesel :: Code P0299 Pops Up At 65 MPH

At 65 mph, egt was running between 1050-1150, turbo at 13-14 psi, rpm 2300. Code p0299 pops up. Before this the turbo would spool up to 28 psi going up hills. After it would not go over 16 and sounded funny. Truck is a 2005 excursion 4x4 with just under 200k miles . Trailer is about 10k pounds. No tuner. What do I need to be looking into? Is this too much for the truck to handle?

Volvo :: 1987 / 740 Turbo Has No Power On Boost

It starts and idles fine and drives fine until the turbo spools and gets past atmospheric.. at this point the acceleration gets worse even though you can clearly hear the turbo blowing (gauge well into the yellow).. checked the ground connections on the head and intake, seemed good, replaced tps, replaced knock sensor, replaced hall sensor, tried another ecu, checked cam timing. Had a volvo mechanic friend looking at it prior to my fiddling with it and he seemed to think the ignition timing was retarded too much.. but I've done everything i can think of to tackle that problem.

Ford 6.0L Power Stroke Diesel :: P0299 Code While Highway Driving?

I just got back from a trip across the state to see the Miami boat show! Truck was running just fine on the trip over, EOT/ECT delta around 9* (seems a little high to me, Im hoping because im running 35's, but can someone back me up on this?)

On the trip back, cruising at 70, I noticed the check engine light went on... I didn't have it under heavy throttle or obscure circumstances... My ScanGauge 2 showed that I had a P0299, which as Ive read means something relating to underboost?

I cleared the code. And the CEL never showed again in the last 100 miles... Could this just be a quirk? Or should I be more worried about it?

Ford 7.3L Power Stroke (1999-2003) :: Rebuilt Turbo Still No Power And No Boost?

Well I am at a loss now. Rebuilt the turbo with a new wheel and kit from Riffraff. I still have no power, no boost and no codes. The new wheel whistles. I can hear it. It sounds way better than the old one. But still no power. I really don't know what to do now.

Ford 6.0L Power Stroke Diesel :: 2004 - Turbo Won't Have Boost?

I have a 2004 Excursion with the 6.0. Lately it seems like the motor just doesn't have the boost it should. Funny thing is that the boost reading through the edge cts seems to be right. Under full acceleration it will pull 27 psi boost and 3900+ ICP pressure. No codes are being thrown. It just doesn't "feel" right (seat of the pants) and it also sounds louder but I don't known this for sure.

Where does the CTS get its boost reading from? The truck has new boots on the hot side from riffraff. Anything I can check?

Tiguan :: Turbo System - Power / Boost Pulse When Under Moderate To Heavy Acceleration

I am experiencing a power/boost pulse when under moderate to heavy acceleration. I'm wondering if this is a sign of my diverter valve failing or another issue withing the turbo system.

I don't have a boost gauge and the main pulsing seems to be between 2800 and 5k in the rpm band.
