Speed Sensor Codes on 2012 Sonata

Hey guys. So I started looking at my car due to the RPMs dropping to 0 and traction control light coming on. Found a forum that pointed me towards the crank sensor and I’m gonna get that switched out. Also I’ve scheduled an appointment with the dealer ship due to some recalls on this car that haven’t been attended to but I ran a code reader on it to see if I could catch the crank code but I found all these instead. Any thoughts on where to start? I’d like to see what I can fix myself before the dealership looks at it 2 weeks from now.

C1205 Hyundai Code - Front Right Wheel Speed Sensor Invalid Or No Signal


C1613 Code - AWC Mode Select Switch System


C1102 Code - ABS Acceleration Switch Circuit Failure


C1102 Code - ABS Acceleration Switch Circuit Failure


C1203 Code - ECM Communication Circuit Malfunction


C1208 Code - ABS Rear Isolation Valve Circuit Short To Battery


C1213 Code - ABS Front Right Dump Valve Circuit Short To Ground

I’d like to add that my check engine light has not actually come on for any of this. And I have some slight stiffness to my steering wheel.
