MAF looks fine.
The IAT sensor has only electrical output. Output from the IAT sensor is measured at pin 34 of connector C0636 of
the ECM, this is a variable voltage/ resistance measured by the sensor to provide air temperature information to the
ECM.
The MAF/ IAT sensor share the same sensor earth. Sensor earth is via pin 9 of connector C0636 of the ECM.

[QUOTE=number9;620628]Have you removed connectors from MAF/IAT and ECU to verified there is a short using a meter? Are you getting a IAT circuit low input failure code?

Not now just P 0112 bad IAT MAF IS working
