P0236 no boost no power

[Powerstroke92]

Tonight while driving my truck became real sluggish all of a sudden and I noticed my cts was reading 0psi boost and wouldnt go over about 55mph. When I checked for codes the truck showed a p0236. I dont have a chip or anything but the previous owner did put a resistor in the map and icp sensor. Are there any cheap easy ways for a college kid to diagnose the problem without throwing money at it and replacing parts that may not be bad.

Ok now im really confused. Went out this morning and cleared all coded now the truck runs fine. What would cause this?

This is the code:
P0236 - Turbo boost sensor A circuit performance - Restricted inlet/exhaust/supply hose, missing hose

Just asking - Were you running it hard / heavy acceration / High boost before this happened? Maybe check your intercooler boots, the electrical connections around the turbo.

Nothing really stupid just hurrying and merging into traffic I didnt even realize it started because after that I was just putting around. Then I noticed the truck felt like it was in limp mode and the turbo wouldnt spool.
