Q: What does code P1572 mean?

Brake Pedal Switch Circuit Malfunction. P1572 on Ford vehicles means the powertrain control module (PCM) has detected an implausible signal from the brake pedal position switch circuit, typically a disagreement between the two internal switch contacts or an out-of-range voltage. The PCM uses this switch to know when the brake pedal is pressed for torque converter lockup, cruise control cancel, and shift interlock logic, so it flags the code when the expected voltage does not match the pedal state.
