Hello,
It is possible to have a no start due to a faulty IAT. On this vehicle the intake air temperature is built into the mass air flow sensor.
I have attached the diagnostic process for the code P0112. Follow these steps as it can help you determine the issue.
Also have you tried clearing the code and see if that allows you to start the engine?
I have attached diagrams below for your reference.
Please let me know if you have any questions.
Thank you.
