Okay elcasador. I have been searching with no luck. Somewhere somebody posted info that provided sensor data, voltage ranges and values to trigger a regen. These were air pressure sensors and gas temperature sensors. I will rack my brain to figure out where I read that stuff and let you know as soon as I can. Sorry to bait you and then provide nothing. It's around, just have to try to REMEMBER! I hate it. I can see the number, words, letters in my head!

Anyway, you should never see smoke now. As you can tell, everyone knows that the trucks used to smoke, now they don't with the latest software. I'll be back later, I hope with some interesting stuff for you. Other guys posted here should remember the stuff I'm talking about, unless I read it somewhere else. It was a guy who quoted stuff from the Ford manuals, really "legalese" sounding stuff.

 

These are trouble codes with explanation, some of them may be of interest to you. There are several posts like this from this guy. He is real helpful. I 'm just throwing this stuff at you so you can get an idea of the sensors in your exhaust system. Hope it is interesting to you. The links below are some threads you may want to read. Just search for trouble code P2002 and you'll get a lot of info about the DPF system.

i'll say it again, PowerStrokeHD is the guy who seems to find all this great info. This is all copied from one of his posts back in November.

P0297 - Vehicle Overspeed Condition

Detailed Description...
This DTC is set when the vehicle speed limiting conditions have been encountered which is 153 km/h (95 MPH) for F250/F350 vehicles and 130 km/h (81 MPH) for F450/F550 vehicles. The powertrain control module (PCM) limits vehicle speed by limiting fuel when these conditions are met. Fuel is limited only to prevent the vehicle from being operated above the respective speeds and once the vehicle is operated below these speeds there is no limiting.

Possible Causes...
Vehicle driven at a high rate of speed

Diagnostic Aids...
Indicates the vehicle has been operated above the calibrated limited vehicle speed.


P115A - Low Fuel Level - Forced Limited Power

Detailed Description...
Fuel level information is sent from the instrument cluster to the powertrain control module (PCM) on the communication link. If an excessively low fuel level input message is received by the PCM from the instrument cluster, the PCM limits the fuel rail pressure (FRP) and sets DTC P115A.

Possible Causes...
Empty fuel tank
Fuel conditioning module circuitry
Fuel tank control module
Instrument cluster
PCM

Diagnostic Aids...
Monitor the FLI PIDs with key ON, engine running. A concern is present if the FLI percentage PID is at 25% and the FLI voltage PID is less than 0.90 volt with a non-matching fuel gauge.


P2002 - Diesel Particulate Filter Efficiency Below Threshold (Bank 1)

Detailed Description...
The powertrain control module (PCM) monitors the efficiency of the diesel particulate filter for a concern. The efficiency of the filter is determined by the amount of restriction in the filter for a certain exhaust flow rate. The diesel particulate filter is preconditioned for 5,000 km (3,107 miles) before the PCM begins to monitor the level of restriction. The test fails when the measured level of restriction is less than the expected level calculated by the PCM.

Possible Causes...
Dirty air cleaner element
Recent manual or thorough diesel particulate filter regeneration
Aftermarket accessories and performance modifications
Modified tailpipe
Exhaust leaks before or near the diesel particulate filter pressure sensor
Leaks in the diesel particulate filter pressure sensor connecting hose
Damaged diesel particulate filter

Diagnostic Aids...
Check for leaks in the exhaust system. Check for aftermarket exhaust accessories and performance modifications that decrease the exhaust restriction. If a new diesel particulate filter was recently installed, verify the diesel particulate filter parameter reset procedure was carried out.

Hey Senix, I had an error code come up on my Banks IQ today. P0927 vehicle overspeed condition. I'm not sure what this is all about and every time I google this code I can't find anything that tells me what it is and if it's serious and what the fix is. Any suggestions. Thanks

 

go to your max value screen. There is will tell you temps and speed/rpms. How fast were you going?

It is a Ford code that is stored, does not hurt anything. You should be able to clear the code but it will stay in the history.

 

What is this software and reflash stuff y'all are talkin about?

 

3 year old thread!!!

 

Ok. Still didn't answer my question.

 

start a new thread. its an old thread and id bet some have moved on (6.7) and wont see your question in this thread.

 

I don't know much about the latest engine programming ford has for the 6.4 engines but there are many helpful 6.4 folks that do, just be patient and somebody will help you. This is an old thread so the info is obviously dated.

 

ON the 08 they only had the egr and diesel particulate filter and cat so in the case of that you would have some black smoke that would be emitted due to not having a doc and scr to farther catylise to what you see on the 6.7l powerstroke

 

No....no black smoke with the 6.4 with emissions intact. Black smoke equals a cracked DPF.
