P0470 code help!!
So I got that code removed the sensor and cleaned it reinstalled it and I have 0 boost.
Clear the codes and they come back immediately after restarting the truck!
Please help as I have work tomorrow! Thanks.

There was a TSB released back in September of 2007 pertaining specifically to 2006 and 2007 model year F-Series applications. The article number is 07-18-04 intended specifically to address P0470 set during ambient temperatures in the minus digits. The updated calibration strategy at the time would ignore EBP input for a few seconds upon cold startup to melt any ice buildup on the sensor. Now, this is an old update obviously. Since then there have been further updated calibrations released, so if yours is at the latest level and/or yours is not an '06/'07 model year, this obviously wouldn't apply.
In answer to the poster inquiring about its location, on '03 to early '05 model years, the sensor is threaded into a bracket atop the thermostat, directly beside the upper rad hose. On late '05 to '07 model years, the sensor is threaded directly to the EBP tube that is secured to the front FICM mounting bracket, under the coolant degas bottle.
This info I quoted from M-chan68.

So, I unplugged the BARO sensor and I finally got boost back.
When I unplugged it my BARO reading went up to 1.0 but I threw a p0107 code and the original code went away. So I assume it's safe to say I need a new BARO sensor?

Possibly but I don't think that's very common. Is the harness ok? EBP is more common problem. Did you try watching EBP an tapping on the sensor with a screwdriver handle? 18.7 seems a little high. 14.4 is ok for MAP depending on altitude. The EBP sensor has a -.5v bias so I think it should be a little lower than MAP wen the engine isn't running.

With the truck running the EBP rating will rise up. I did not try tapping on the sensor-EBP sensor could have failed as well because I cleaned it with brake cleaner so it could be that sensor? I will probably end up changing the EBP and the BARO sensor. They are cheap enough. Atleast with the sensor unplugged I can drive it to work tomorrow.

Well, that sound right, it should come up a bit at idle but mostly when the boost come on. Here's my notes on the values for them.
EBP
EP 103 (15) 110 (16) 110 (16) 55 - 607 (8 - 88) kPa (PSI) Exhaust Pressure
EP_V 0.8 1.2 1.3 0.4 - 4.7 VOLT Exhaust Pressure
MAP
MAP 96 (14) 96 (14) 103 (15) 41 - 324 (6 - 47) kPa (PSI) Manifold Absolute Pressure
MAP_V 1.30 1.33 1.40 0.5 - 4.5 VOLT Manifold Absolute Pressure
BARO
BARO 96.5 (14) 96.5 (14) 96.5 (14) 50 - 120 (7.3 - 17.4) kPa (PSI) Barometric Pressure
EBP
EP 103 (15) 110 (16) 110 (16) 55 - 607 (8 - 88) kPa (PSI) Exhaust Pressure

Got a friend with a 6.0 that you could swap just to test it.

I do not know anyone with the same truck as me to swap it out on...
I ordered a new MAP sensor, EBP sensor, and BARO sensor-So lets see how this works out.
Ive done a TON of reading on the P0107 code-a bunch of threads about it but no one ever post's up results when fixed. Very annoying, and it seems like it could be the MAP sensor, very rare to see a bad baro sensor-or its the PCM(which I really hope its not)
I have a good connection with my parts supplier so if the parts don't fix it I will return them.
After unplugging the BARO sensor the P0470-code no longer came back-even after the 20 mile commute to work. I did see my EBP pressure spike up to 40.4 and MAP stayed right around 20- BARO was a solid 1.0(all readings in PSI)
