I have codes C0040 and C0245. There’s so many different answers online.

I know it's really difficult sometimes, but hands-on inspection by a professional is needed. The codes don't tell anything when you don't have a physical inspection to go along with it, perhaps also with a digital voltmeter/ohmmeter. It's too hard to know what's going on, and the reason there is no internet answers is because -- there are too many variables to know what's happening for your particular vehicle and concern. My gut feeling - which is only that - would suggest that something is happening with the wiring to the right front speed sensor when you make the right turn, due to stress on the harness. This means nothing without inspection, so seek local guidance near you. https://repairpal.com/auto-repair-near-me
