P0107

I got a code P0107 i thought it was for the MAP sensor, but, it was actually for the barometric sensor (sensor inside the MAF sensor). Here is info from ALLDATA:

CIRCUIT OPERATION

A 5-volt voltage is supplied to the barometric pressure sensor power terminal (terminal 1) from the ECM (terminal 81) or PCM (terminal 46) <A T>. The ground terminal (terminal 5) is grounded with ECM (terminal 40) or PCM (terminal 16) <A T>.
A voltage that is proportional to the atmospheric pressure is sent to the ECM (terminal 85) or PCM (terminal 55) <A T>from the barometric pressure sensor output terminal (terminal 2).

TECHNICAL DESCRIPTION

The barometric pressure sensor outputs a voltage which corresponds to the barometric pressure.
The ECM or PCM checks whether this voltage is within a specified range.

DTC SET CONDITIONS

Check Conditions

2 seconds or more have passed since the starting sequence was completed.
Battery positive voltage is higher than 8 volts .

Judgement Criteria

Barometric pressure sensor output signal has continued to be approximately 50 kPa (7.2 psi) or lower (approximately 15,000 ft above sea level) for 10 seconds .

TROUBLESHOOTING HINTS (The most likely causes for this code to be set are:

Barometric pressure sensor failed.
Open or shorted barometric pressure sensor circuit, or loose connector.
ECM failed.
PCM failed.

Did you notice how it said for the DTC set conditions if its reciving 7.2 PSI for more than ten seconds it will set the code, is this because im turbo now? Have u guys gotten this code before? and i dont think the MAF or barometri sensor should even see any PSI becuse its BEFORE the turbo right?
