Code P1111 is just a system readiness code. The P1549 gets triggered due to the intake manifold tuning valve (IMT) not getting proper power or having wiring or functionality issue.
I have attached the trouble shooting guide for code P1549 below. Follow those steps, as it can help you determine the issue.
Let me know what you find or if you have any questions.
Thank you.
