DTC Codes

P006B MAP/Exhaust Pressure Correlation
P2263 Turbo/Super Charger Boost System Performance

also sct is picking up codes u0100 and u0115

Anybody know why it is throwing these codes? I am running sct with innovative diesel tunes.

The truck takes forever to warm up, and it pops and blows tons of white blueish smoke when cold, the idle changes to almost a lope idle sometimes and almost sounds like its missing, i have no idea what is going on.

Are you pulling these codes with the SCT? Sounds like you could have a screwy sensor, but the pop points to hardware (maybe Injectors)

chadc · Jan 23, 2012

The truck only has 22k on it so I hope its not an injector, it only pops when you go more than half peddle when its cold, im using a scanner my friend has to pull the first 2 codes and the sct is pulling those other 2

The truck is a 2010 f350 with dpf delete, 4in turbo back, afe intake, sct with innovative diesel tunes, and a southbend dd clutch

The "u" codes are nothing to worry about. The issues at idle are what would worry me.

check your MAP, EBP, and Barometric pressure. i have a feeling one of those sensors are out.. my EBP sensor went out and it acted the same and pulled the same codes. minus the smoke.

chadc · Jan 23, 2012

How do i check these? When i bring the MAP and EBP up on the sct the MAP gauge flashes and the red alert light flashes also, im not sure how to check barometric pressure

powerstrokin15 · Jan 23, 2012

well bring up the ebp and map, and turn the key on. not the engine. and see what they both are. they should be the same

chadc · Jan 23, 2012

the map was around 90 and the ebp was around 440

your ebp was 440psi? you are reading exhaust back pressure right?

jdgleason · Jan 23, 2012

With the key off?!!?! Both sensors are hammered. Get new ones.

Whoa!

Both are way out. They should be around 101-103 depending on altitude. Pull them and clean them and then re check. Should take about 10min.

ohh.. i was curious. LOL but still they seem off

forcefed6.4ford · Jan 23, 2012

they are.

chadc · Jan 23, 2012

EBP is 449

MAP KPA is 97

Key is on motor is off

forcefed6.4ford · Jan 23, 2012

Yeah. Pull them and give them a quick cleaning. Might get everything working for cheap. If not the sensors need to be replaced.

On edit. When the EB sensor is out, take the tube off as well and make sure there is nothing in that too.

chadc · Jan 23, 2012

Where is the eb sensor located?

forcefed6.4ford · Jan 23, 2012

Driverside up pipe. directly behind the fuel cooler. 1" and 5/8" wrench to remove iirc

chadc · Jan 23, 2012

Cleaned the EB sensor it was completely packed full of black soot, im still getting the same readings, but the truck seems completely different its running a hell of a lot better, im just not sure why im getting the same readings
