The ambient pressure sensor measures the air pressure.

Hi JFP, thank you for the reply. I did see something like this in one of the posts while I was searching.

From what I understand, the proper way to diagnose this would be to check for voltage and ground at the appropriate pins in the harness to the ECU and if that's good, then to look for the MAP output in Durametric? My problem is I'm not seeing anything labeled ambient pressure sensor in the wiring diagrams for the DME 7.2 in the Bentley manual. I see a "Sensor, Differentiale E12/E11", but it looks to be external of the ME and feeds to the two Camshaft Sensors. I also don't recall seeing a PID for MAP in Durametric.

Does anyone have troubleshooting procedures or pictures, or even past experiences to help me dig into P0107? Also wondering if this can be causing P1126? Any help is appreciated. Thanks!
