If your Ford car displays the C0040:64 code, it’s time to take a closer look and assess what could be causing the issue. The C0040:64 code is a Brake Pedal Switch “A”: Signal Plausibility Failure. This can be a tricky code to diagnose and repair, but getting it fixed as soon as possible is essential. As you may know, code C0040:64 indicates a plausibility failure of a single input parameter. For this code to be triggered, the control module must detect that the brake pedal switch input has been continuously active for more than 6 minutes when driving faster than 20 km/h or after accelerating up to a speed greater than 40 km/h and decelerating down to a speed less than 3 km/h 4 times with no change in brake pedal switch input. To avoid further damage, it is essential to address the C0040:64 code as soon as it is detected.
