P132B - Turbocharger Boost Control A Performance

Is your 2011 a job 1? Does a shutdown (key off) and restart resolve? When was the last time you had the firmware updated (IDS version)? In my experience, the occurrence was reduced with firmware around mid 2012 if I remember correctly or at least easier to self resolve. Instead of the truck being disabled because a restart wouldn't fix the issue, the newer IDS version would resolve with a restart (truck reboot).

The best way I can explain this is the vanes get stuck closed. The engine sound is louder (more clatter) and EGTs will increase significantly. I have had this occur at start up where pulling out onto a highway is an issue or I have had this occur while driving such as at 55 MPH where it was fine previously. It is random where no specific action causes the issue.

This issue has plagued my truck at least 3/4th of its life. I continued to have the issue with the June 2017 IDS version which was the last update installed to mine. I'm convinced at this point the fix is likely replacing the turbo with the 2015 model. Or just get rid of the 2011 sadly.

Due to two years of various and expensive out of pocket emission issues with no end in sight plus other expensive issues, I switched to custom tunes for the ECM/TCM. This so far has created a stable truck for eight months which is progress. I bring this up because I also haven't had this VGT issue. Normally this would have occurred at least once or twice during this time. I'm not calling it resolved yet but so far so good. I'm not saying tuning is the answer, I would rather have remained stock but I had reached my breaking point and didn't want to buy a new truck when mine is physically in good shape.

 

 

That's a good point. I did have the waste gate solenoid replaced in Feb 2018 because of the buzzing/mini air compressor type noise while running and +/- 20 seconds after shutdown. However, I'm fairly certain I had this VGT issue at least once with the new solenoid. The specific occurrence I remember it was working for five miles then pulled away after stopping at a traffic light and performance was terrible with the familiar sound of the engine when this occurs. Had to pull over and restart. You don't want to drive it much because even light acceleration puts EGT1 at >700°F.

Another thought is I had to replace the MAP sensor. I started the truck one afternoon and it sounded as if there was blockage in the exhaust. Multiple restarts didn't resolve. When I pressed the accelerator to 1,000 RPM or so, exhaust was entering into the cab through what appeared to be the air vents. If the tone of the engine wasn't enough I decided to drive it around the neighborhood about 1/4 mile to see if it would clear and the exhaust fumes made it miserable even with the windows down by the time I made it back. Installed the new MAP sensor and was an immediate fix for that first time issue. I tried cleaning it but ended up making it worse, the sensor part is very easy to damage. Mine was packed full of soot.

 

 

kper05--- did you delete or just get a custom tune? I've had this problem on my 2011 f350 dually, pulling my rv. My map sensor had been replaced last year, so I think it is good. Took it to dealer, but code was not stored in computer. I sure would like to get resolved with my extended warranty. If anyone has any solutions without deleting, I would like to hear.
Thanks

 

Removed the DPF, custom tune after my third round with emissions issues (not because of this issue). I left the EGR cooler in place for now. This also resolved my stuck vanes issue with the turbo as it hasn't occurred in a year now and it was a regular issue.

If you can get this reproduced at the dealer or it stored the code, the ESP will likely cover it if you have PremiumCare (which does list the turbocharger). If you purchased yours new and have never had it flashed (firmware update), that will be the first step they do. You won't get a new turbo but maybe they'll at least troubleshoot it. However, what extended warranty do you have with a 2011? Any ESP option from 2010/2011 would be expired by now (I don't think the 8 year was offered then for example).

My opinion, I think the long term fix is a 2015 turbo swap... it's a little annoying as an early owner Ford didn't figure this out in at least seven years of firmware.

 

kper05, thanks for responding. Yes I have premium care, bought the truck about year and half ago, one owner, only 69,000 miles at purchase. So it qualified for premium care warranty. Oasis on truck was good, very clean for a 2011. It has been very reliable except for map sensor last year,
This P132b is recent , trip to New Mexico and Colorado, Like you, I have been able to get it to ( perform properly ) by stopping and turning ignition off , and restarting. First couple of times it happened, check engine light came on. I monitor with torque pro, was able to clear code and proceed. After those times light did not turn on, but when i started driving , there would be very little boost. The morning I took it to dealer, light was off, but code was stored in computer. Truck ran as normal driving to dealer. When they checked it, there was no code stored in computer. The tech explained to me when you turn ignition to on, truck does a test for systems OK, if good it will erase codes. So I'm hoping to be able to get it to dealer either with code present or running with no boost. There seems to be very little info for this code with the 6.7, that"s the reason for my questions. There is a lot more info pertaining to the 6.0. I had a 01 F250 with 7.3 ( very good truck), but it did not have legal capacity to tow my current 5th wheel. Hindsight, kinda wish I had kept it and just dealt with overweight issue. Thanks again for the response.

 

I think this particular issue is a rare one which further explains the lack of info or a fix that doesn't involve a 2015 turbocharger. It's becoming obvious this issue is resolved with firmware though.

I had the issue occur most of the time without a CEL but did get the DTC a few times. I couldn't figure out what did or didn't cause a DTC/CEL because the symptoms were the same (no boost, high EGT).

The 6.7L is a great engine, you just unfortunately ended up with one of the 2011's that has this odd issue. What is the build date?

 

Not exact on date ( i keep truck covered) too lazy to take cover off . It is an early build, in 2010. I am covered with a warranty, my concern is not being able to reset, or turbo breaking leaving us stranded on side of road. Some roads we have traveled there is no shoulder. And sometimes no cell service. Trying to get as much info and knowledge I can concerning this trouble code, and what if anything can be done about it.

 

did you ever find out what was causing it? I have same problem just bought truck from a friend. Egr and dpf with tune! Can clean but same happens with low spool.

 

I hade an intermittent occurring P132B code on my 2012. It started as every few months, and slowly became more and more consistent. Finally the code became constant and the truck would make little to no boost at times, and overboost other times. I completed all steps of the P132B pinpoint test, and by order of elimination found that the turbo was no longer actuating properly, requiring a replacement of the turbo. There are several items within the pinpoint test that could lead to the occurrence of the P132B code, but in my case it was the turbo.
