T1N '06 with only 45K miles. Went in LHM on a trip from Los Angeles to SD via 5. Symptoms: Lost power; would not go faster than 55mph, accelerator pedal had no effect beyond keeping it at 55mph. No CEL or codes thrown, so while this appears to have been a computer actuated Limp Mode the absence of codes is puzzling. I made a stop at a gas station to inspect the vehicle, and could not see any visible issues. But as I continued to poke around, noticed a hairline like line, maybe an 1.5 inches long on top of the charged air hose a couple of inches before it joins the intake manifold. I squeezed it a bit, and bingo! This was really lucky since if the crack was on the underside of the hose, I would not have found it at all, and since it had not thrown any codes, it would not have helped to get it to a dealer or repair shop, they would be guessing and replacing stuff in an effort to diagnose the problem. Due to the numerous threads here about the turbo resonator, the first thing I did, when I bought the truck used, 2 years ago, was to bite the bullet and get the solid alum resonator eliminator one less thing to worry about.
Ok, the fix: lucky I had a bicycle tire inner tube (old and discarded from too many flats), which I just happen to have for emergencies as I felt its better than take to fix busted hoses as one can tension more than, say, silicone tape or duct tape, but I do carry duct tape too. At any rate, its the perfect wrap if you are careful to overlap the tube around 50% as one would wrap it around a bike handlebar. By stretching the inner tube it provides enough tension to close the cracked hose. Once one has wrapped it beyond the crack, all one has to do is wrap it back towards the other end, cinch both ends together with a double knot and done. 5 minute repair that might be stronger than the original.
BUT this experience has warned me that those charged air hoses from the turbo upwards to the intake manifold need to be renewed. So when time and budget allows, I will be replacing them, including that MAP sensor which could also fail and trigger a LHM. Also, if you are cyclist, and have those discarded inner tubes, put one in your tool box.
Cheers!
