[s-cars] No boost....code 2222

[Premiere Investment Properties, LLC.]

Hi all
I just recently got a new to me 92 S4 and am having boost issues....After a 
overly enthusiastic freeway onramp excursion, I now have no boost, I 
assuming one of the 150K+ original hoses has let go, but what gives with the 
code (2222 (Blink Fault Code), Pressure sensor ECU Pressure sensor 
defective, Repair or replace ECU)  that I pulled? Which hose is most likely 
to go, or where should I start? Any help would be appreciated, it sucks not 
having the power :-(
TIA
