Possible bad sensor?

Hey guys,
Just got around to checking my voltage. My MAP is 1.231V and my EBP 0.86V with KOEO. With KOER, My EBP jumps to 1.22V. According to a TSB (below) they should be about the same. One of them is obviously bad, but which one? I'm located in Surprise, AZ, which is about 1100 ft.

Quote:
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.

Well if your engine isn't running you shouldn't have any EBP so it stands to reason that it would jump with the engine running. What was your map at for the KOER?

After further review, I am thinking my MAP sensor is bad and the PCM commands the turbo to increase EBP so that they are consistent. Does anyone know if there is a way to check?

PID for MAP
key on: 96 (14)
low idle: 96 (14)
High idle: 103 (15)
Operating range: 41-324 (6-47)

kPa (psi)

Don't know if those will help, but that is what I found.

Hmmm, well the MAP signal matches those from the book. Do you also have the EBP reference values? I really appreciate your assistance.
