I have a yellow check engine light on my dash that recently turned on. Connecting my AutoXray diagnostic tool I am seeing two codes: P0073 Ambient Air Temperature Sensor High Input and P0107 Manifold Absolute Pressure/Barometric Pressure Circuit Low Input. I presume my problem is the Intake Air Temperature / Barometric sensor just down stream from the air filter and upstream from the turbo.

The other possibility is the MAP / Temperature sensor in the intake manifold. Any recommendations? Thanks in advance for your insight.

It's a miracle!!!! I am not sure what happened but the check engine light disappeared and I was able to clear the DTC(s). The only possibility that could explain this is water got into one of the sensor connectors causing the problem. That or the ECM sneezed for 7 starts. Anyway all is well with the old goat.
