Been running great for about 500 miles after total rebuild with only a P006a code until today. Driving normal up to a light and take off and it struggles to build boost up to 15psi and EGTs skyrocket to 1200 out of no where. I let out of it because i see that and notice its not building enough speed to shift. It finally shifts but i have to feather the pedal to get up to speed. Anything over 1/4 throttle makes egts soar. Wtf?!?!? It only has an FICM tune on it and its ran fin till this evening. It almost sounds like its struggling to get air and feels horribly sluggish. Other than that it idles fine without issue.
Codes are
P006a -
Some 2003-2004 F-Super Duty and Excursion vehicles equipped with the 6.0L engine built on or before 9/29/2003 may experience a P006A or P132B Diagnostic Trouble Code (DTC) with a lack of power condition, surge, or turbocharger flutter after performing Field Service Action (FSA) 06E17, or after recalibrating the vehicle with the inferred Exhaust Pressure (EP) strategy.
The P006a is used to say that while trying to infer ep, the map and maf didn't correlate. p132b is used to say that the turbo didn't produce the estimated changes in map and maf while being run through it cycle. They both can be caused by aftermarket equipment. Hope that helps
P0102 -
This might help in stating to diag it. hope you have a multi meter. there is more to the pin point test.let me know if that helps to get started
Possible causes:
restricted air flow
MAF sensor disconnected
VPWR circuit open to MAF
PWR GND circuit open to MAF
MAF RTN signal open
MAF signal shorted to ground
mechanical failure
MAF sensor
PCM
Inspect air intake for restrictions
Key off.
Disconnect the MAF sensor harness connector.
Key on.
Measure the voltage between the MAF sensor VPWR circuit pin 2, harness side and MAF PWR GND pin 3, harness side.
Measure the voltage between the MAF sensor VREF circuit pin 4, harness side and MAF PWR GND pin 3, harness side.
Is the voltage greater than 10.5 volts between pins 2 and 3 and is the voltage approximately 5.5 to 6.5 volts between pins 4 and 3

P0275 -
cylinder #5 contribution/balance fault
P0500 -
VSS (vehicle speed sensor) you can check the sensor on the rear diff with an ohm meter, should be between 800 and 1800 ohms. Though I have found a few threads that correlated this to a PCM problem... may want to check the plugs there, seems like you have a bunch of odd electrical problems that all of a sudden popped up (loose connector on the PCM maybe?)
P0683 -
GPCM (glow plug control module) I have the test specs for this, I'll email them to you.
P1000 -
testing not complete or some other crap, it's an nonsense code that means nothing and will go away. It's only there from not doing a "complete test" as the software thinks you should be doing. Ignore this one.
P1378 -
not enough voltage to the FICM.
Could be this:
Various Electronic and Driveability Symptoms and Codes:
2005 F-Super Duty trucks built before 5-11-05 may exhibit various electronic-related symptoms due to loose/miss-installed fuses in the engine compartment fuse box. These symptoms may be intermittent. The fuses should be inspected to verify they are installed into the terminals in the fuse box and not along side the terminals.
Fuses--Symptoms
#9, 20 amp: Trailer turn signals inoperative
#10, 10 amp: Check Engine Light; Codes P1633, P0446
#11, 10 amp: Speedo bounce, ABS light, Cruise control inop; Codes U1900, U2023, P0500-P0503
#12, 2 amp: Cruise control inop, TBC Fault displayed, chime; Code C2803
#13, 15 amp: Day time running lamps inop
#15, 15 amp: Crank/no start, bucking, stall; Codes P2614, P2617, P1378
#17, 10 amp: A/C inop or not cooling
#18, 10 amp: Crank/no start, bucking, stall; P2614, P2617, P1378, P0611
#20, 10 amp: Trailer back up lamp inop
TSB 05-11-14
Looks like #15 and #18 might be possible suspects.
P1378 is a low voltage supply to the FICM. If that helps anything...
A buddy of mine from when I used to be on dieselbombers had something similar: http://www.dieselbombers.com/6-0l-performance/52005-ficm-code-wont-start.html
Holy crap from 1 code to this in 10 minutes!?!?!? I just spent 13k on this thing and its not going back to the dealer. Any ideas? There isnt a boost leak because i got it up to 20 psi at one point coming home but it was a long stressful drive.....
