Default trouble codes c1201, c1231

I had a check engine light, and a track light on in my 2010 Camry. Codes are C1201 brake boost sensor circuit range/performance and C1231, steering angle sensor. I am getting an alignment next week, so I thought I would reset the steering angle sensor after, but I could use some info on the C1201. Thanks in advance!

There is a TSB for C1231. TSB-0086-13

Get the C1231 code fixed and the other code may go away.

C1201 is an ECM malfunction.

there seems to be some conflicting information out there on a 2010 camry a 1201 is supposed to be brake boost sensor circuit range/performance, whatever that means. not ecm malfunction?? so which is it also, I looked up the tsb and it says for the 1231 that the ecu logic was modified? very confusing. so, can I "reset" the steering angle sensor or do I have to take it somewhere for this logic modified business???? thank you so much, all of this is very confusing!

There could be many causes and without the official Toyota diagnostic tool, finding them can be challenging. So do the easiest first.

C1202 is brake fluid level low or brake fluid level sender problems.

Some code readers appear to cause the computer problems with the steering angle and give a code. Reset steering angle.

C1201 is a malfunction signal received by ECM.
