When I hooked up my Edge CTS, this weekend, I got a P0299 code, turbo underboost. From all that I have read, it sounds like the ebp sensor. Who is the best person, on this site to order from and does anyone have a picture showing this sensor? I'd like to get it ordered and try to replace myself, this weekend.

 

P0299 could be over/under boost, sensor, dirty or shot turbo or actuator also. When I had it the turbo had to be replaced. Was beyond cleaning according to the tech.

 

It could also be a cracked flex joint or leaking CAC boot but I'd clean the turbo, EBP tube, EGR valve, and MAP sensor tube before I spent $$$ on an EBP sensor.

 

I get this code once in a while. I clear it, it sometimes come back after 1000 miles or so, I do not worry too much about it, I guess it could be a glitch with an EGR sticking, a turbo sticking a bit, a Map sensors too sensible.

I get it only when loaded

 

For the past two months I went threw the whole P0299 underboost issue. I spent good money after bad changing sensors, cleaning the EGR cooler and turbo. At the end of the day I replaced the turbocharger which is a good bet on what you'll be doing. I would say if you got the dough replace the EGR cooler w/a Bullet Proof ($350) and replace the Turbocharger w/a Garrett HP ($1400. Do not buy a rebuilt). Your going to have to do it sooner or later, may as well take it like a man!

Also, when I did the work, my 05 6.0 PSD runs like a brand new X. I could not be happier (at this point anyway).

Good Luck!

 

Lets check some things since you have a gauge

At KOEO=Key On Engine Off

so at KOEO check Baro,Map,EBP readings they need to be within .5psi of each other

 

Baro. Psi 14.8
Map psi 14
Not sure how to get ebp

 

IDK what to say to that there supposed to be within .5 psi of each other

yours very well could be within .5 psi of each other

Maybe your gauge just shows whole numbers for Map

I think it would be off more if you had a bad MAP sensor

 

Is there a way for me to read ebp?

 

IDK if your gauges wont read it

you could Backprobe it with a DVM but then you would have to convert the volt reading to a pressure reading

Normal EBP signal reading should reflect atmospheric pressure with the key on/ engine off. Typically, this is 14.7 PSI/0.88-0.9 volts at sea level, decreasing one PSI/0.10 volt for every 2000 feet of elevation. It should be within 0.5 PSI of BARO and MAP sensor pressure signals.</TD></TR></TBODY></TABLE>


Theres a bunch of stuff in the spreed sheets do you have those?????

 

heres some more info
