P1572 - Brake Pedal Switch Circuit

WARNING: This page does not describe the selected car, but rather 30 other vehicles, including the 2004 Mercury Sable, 2004 Mercury Mountaineer, 2004 Mercury Monterey, 2004 Mercury Marauder, and 2004 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.
P1572 - BRAKE PEDAL SWITCH CIRCUIT

Description:  Indicates the brake input rationality test for brake pedal position (BPP) and brake pressure applied (BPA) switches has failed. One or both inputs to the PCM did not change state when expected.
NOTE: On vehicles with stability assist, the BPP switch is connected to the ABS module and the ABS generates a Driver Brake Application (DBA) signal, which is then sent to the PCM.
Possible Causes: 
  • Misadjusted brake switches, BPP or BPA.
  • Blown fuse.
  • Damaged BPP switch.
  • Damaged BPA switch.
  • Open or short in the BPP circuit.
  • Open or short in the DBA circuit.
  • Open or short in the BPA circuit.
  • Damaged PCM.
Diagnostic Aids:  DTC P1572 is set when the PCM does not sense the proper sequence of the brake pedal input signal from both the BPP and BPA switches when the brake pedal is applied and released.
