so i was on my way to work tonight. not really beating it but kinda showin off my exhaust off a little bit. and i saw the wrench light illuminate and it started idleing really rough as if the ficm was goin bad. i got in the parking lot and hooked my code reader up and it shot me the fallowing codes

P0107 Manf Abs Pressure/Baro Pressure Circuit Low Input
P0299 Turbo/Super Charger Underboost
P0405 Exhaust Gas Recirculation Sensor A Circuit Low
P0472 Exhaust Back Pressure Sensor Circuit Low Input (PROBOBLY BECAUSE OF MY STACK)
P2104 Throttle Actuator Control System - Forced Idle
P2122 Throttle/Pedal Position Sensor/Switch D Circuit Low Input
P2285 Injector Control Pressure Sensor Circuit Low
P2139 Throttle/Pedal Position Sensor/Switch D/F Voltage Correlation
P2138 Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation
P2132 Throttle/Pedal Position Sensor/Switch F Circuit Low Input
P2172 Throttle Actuator Control System - Sudden High Airflow Detected

the last few im sure its because it was stalling out and i pushed the pedal down kinda far to get it to revive. idk if i should erase these codes and wait to see if they come back. one of the guys here at work was saying it sounds like a controller because they are so far spread out. im just so confused. im supposed to make a 6 hour trip with this truck in a few days and dont want to get stranded in the middle of B.F.E please give me your advice

 

From all the low circuit codes they arent getting enough juice so the sensor is just defaulting.More than likely you have a chaffed wire somewhere or a loose connection.Check throttle postion,egr valve,icp,ep,bap,map sensors and all your pcm connections.I would also test your batteries they should be around 12v just to make sure.If all still doesnt work i would try unplugging the icp sensor that would be the one to most likely fail and cause problems.

 

Im running a hypertech max energy programeri usialy run.it on.stage two but ive had it on stage 3 for the past few days to see what kind of fuel mileage i ca get with it. do you think that could be causing tje computer to be like woa wtf man?

---AutoMerged DoublePost---

so as an update, i downgraded my tuning and i got rid of all 11 codes but its throwing me a new one. im getting p1000 which from my understanding is that the computer was not done running all of its checks before i checked for codes. after work im going to drive it home and when i get home i will check for anymore dtc's. im kinda starting to think that the injectors wern't able to keep up with what the programer wanted and was throwing those fuel codes. that or my computer took a ****. i really hope its not the computer. i can always put some bigger injectors in

 

Put it back to stock and do all your troubleshooting WITHOUT the programmer hooked up.

This is going to be an easy fix.

Start with checking out the EPB sensor, it's located on the drivers side, coming off of the exhaust manifold. There will be a stainless tube coming out of the exhaust manifold, follow it up and you'll see the sensor. Remove the sensor and the tube and clean both. Inspect the wire harness going to the sensor. That will most likely clear the turbo code too.

You may have an ICP sensor going bad, or you might have a leak in the high pressure oil system. You really need to log this with a scanner, but you'll want to watch ICP desired vs. ICP actual, and monitor IPR duty % cycle at the same time. I would do it cranking, at idle, and driving and do some WOT runs and see where it goes under WOT. On an 06 it should go up to about 4000psi under WOT. Could be leaking standpipes/dummy plugs or STC fitting finally going.

 

Ya if all you have now is p1000 you should be good that is just the obd system readiness hasnt complete yet. Thats normal it will go away after all the tests are complete.once you start it up and drive it.

 

The problem might be from using the generic programmer itself, since it's not even a programmer. It just fools the PCM and ICP into thinking it's running too low of an injection pressure to add more fuel. It's more of a "trick your PCM into doing something it shouldn't device" than a programmer.

Drive it around for a while like that and see if the codes come back?

 

So I took the programmer off and I out almost 100 miles on it and I have gotten no problems at all. So Im pretty sure I'm going to get rid of the programmer and get a nice bully dog

 

The bullydog isn't going to be any better than what you just took off...

SCT with custom tunes or nothing.
