Hello,
I have included for you in the diagrams down below the factory diagnostic troubleshooting guides for both DTC P0237 and P1185. These guides should pinpoint the cause of both these DTCs so you can get it fixed, and fixed right the first time. It will require you to use a multi-meter, so I have included a link below for you if you are unfamiliar with how to use one.

Please go through these guides and get back to us with what you are able to find out.
Thanks,
Alex
