Tundra 200k Mark

Hi folks. Asking for help. My 2007 4.7 Tundra just hit the 200k mark and these issues start popping up:
VSC - flashing
skid light - on
ABS light - on,
engine light - on.
brake light on my tail lights turn/remain on (soon as my ignition is on).

Codes showing are:
C1201 - (1) Brake boost sensor circuit range/ performance, (2) Engine control system
P0724 - (1) Brake switch B input circuit High

What I have done so far and all checked good:
- changed/adjusted the brake light switch
- changed both tail/brake lights
- checked for short using test light and pulled all fuses one at a time
- checked for bad fuses

I'm just a weekend mechanic and my knowledge/capabilities ended here. Please help on what else I could do. This truck is my work truck and I don't have the funding to pay a mechanic. Have any of you folks had this issues? Thanks.

 

Ecm?

 

Not my chart but might help.

 

Brake switch may have gone bad, check your battery terminals and clamps, ensure they're clean.
