Take a note of the current codes, wipe them off and check in a day or two if any comes back. No reason to troubleshoot codes that may have been set long long time ago.

 

Yup did that , 2783 & 27D5 returned

 

Likely an air leak. I'd start troubleshooting from checking pressure regulating valve. #13 on this diagram
