Alright i was goin down the road and as i was passing a truck its like i lost all power and went from 45lbs of boost to like 10 at the max. and when ever i trun my comp box on and off its not workin but its lite up. im lost i need some help. the code it through is p-pcu. anybody no what that is?
 
ok sorry the code on the p-pcu is p1693. and the code on the p-ecu is p0237
 
P0237
MAP Sensor Voltage Too Low

and P1693 is a companion code that basicly lets you know there is another code preset
(IMO not a big deal)
 
p1693 - DTC detected in Pcm or Ecm
p0237 - Turbo Charger Boost Sensor Circuit Low
 
how much do they run? i did run the truck with out the map sensor hooked up for a lil bit can i just un hook it?
