If I smash on the brakes, my 2011 Ranger will throw on the traction control light and store this code: c116a-e0. I can clear the light by turning the engine off and restarting it. If I mash the brakes again, it comes on. Right before the light comes on there's a physical "click" in the brake pedal. It's getting worse... I have searched and found a lot of info, but nothing quite exactly like this... any thoughts before I start pouring money into it?

2011 Ford Ranger Sport, 85000 miles...

I tried to use the img tag, but google photos rather sucks at sharing, so here's the link... meh.

If it still has it, and it should based on the code definition, replace the hydraulic pressure switch in the master cylinder first and see if that fixes it.

That's a bit-mapped code, which give a bit more specific info, but the gist of it is that the pressure transducer switch is telling the ABS module something different than the brake pedal position switch about whether the brakes are applied or not.
