2000 Lincoln LS P1572 Fault Code: Idle Control and Auxiliary Input Issue - How to Fix?

Model: 2000 Lincoln LS Fault Code: P1572 Posted: 2009-04-20 22:04

My 2000 Lincoln LS engine light is on, and my OBD-II scanner shows fault code P1572. The code indicates an issue with the Idle Control system and Auxiliary Input. I've done several repairs myself but need guidance on where to start. Can anyone confirm what component should be replaced or checked to resolve this? I want accurate information based on actual vehicle specifications.

Please verify the exact fault code displayed. P1572 is actually associated with a Brake Pedal Switch Circuit Malfunction, not Idle Control or Auxiliary Input. This may indicate a misread or incorrect code entry.

The P1572 code points to a brake pedal position switch circuit issue. First check fuse #235 (15-amp) in the central junction box. If the fuse is intact, inspect the brake pedal switch and related wiring for corrosion or damage.
