Can anyone provide assistance in troubleshooting a c1446 on an 08 f250?

Question

I have a 2008 F250 6.4l. The brake light and telltale "check brake system" keeps flashing on the dash. I plugged in a generic code reader from AutoZone and the only code is a C1446. My SCT Livewire TS only shows a P703. Are these the same sensor/switch or are they separate issues. I've had the P703 code since I bought it 2yrs ago, the other one just started last month. Thanks for your time.

Answer 1

These 2 code are both the same it just one is pulled from the ABS system. When it this code and these are common condition on the mating connector of the brake pedal position switch terminal  connection if you look at the mating terminals form the outside you may see corrosion build up. on the B+ or the battery voltage connection. if ther is corrosion  separate the terminal connection use a safety pin clean it out as much and put together
