I have a 2011 F150 eco with 80k on it. Recently the front brakes and rotors where getting pretty bad, but right before I replaced them the advanced tractor, brake light, abs lit up. I scanned the truck and got a C1140 brake pressure sensor signal failure. I replaced the master cyl with a used one thinking it was a sensor issue. That did not help. I checked all the fuses and nothing blown.

any thoughts?

 

sorry the code is C1440.

 

Follow diagnostic procedure in service manual, don't just buy parts and guess.
