Hi All! I am brand new here and just rescued a 2003 Accord EX V6 with 218K miles. It has almost all the dash lights on (ie ABS, brake, CEL, Traction, etc) and a LOT of codes. Below is a list of what I have.

After spending a lot of time researching this so far, I am thinking of a strategy of replacing the ABS modulator first then seeing what goes away before touching the O2 sensors. I can't see all these sensors legit being bad (especially the O2 being both upstream in different banks). What do you all think?

1) 11-1 Right Front Wheel Speed Sensor Open or short
2) 13-1 Left Front Wheel Speed Sensor Open or short
3) 43-1 Right Rear Wheel Lock
4) 61-1 Battery Voltage Malfunction
5) 68-1 Brake Switch Malfunction
6) 84-1 Sensor Logic Malfunction
7) P0175 : Engine receiving either too little air or too much fuel [O2, MAF PCV causing]
8) P2243 : Issue in oxygen sensor reference voltage circuit UPSTREAM [Rear Air/Fuel Ratio (A/F) Sensor (Bank 1, Sensor 1) VCENT Line High Voltage] BACKIDE OF ENGINE CLOSEST TO FIREWALL
9) P2A03 : Issue in oxygen sensor 1 circuit performance on bank 2 [Front A/F Sensor Circuit (Bank 2, Sensor 1) Circuit Range/Performance Problem]
