What does code C057E mean?

Q: What does code C057E mean?

Brake Booster Temperature Sensor A/B Correlation. The C057E code indicates that the anti-lock brake system (ABS) control module has detected a correlation error between the brake booster temperature sensor's two internal sensing elements, which are designated as channels A and B. The module compares the voltage or resistance signals from both channels and sets this code when the difference exceeds a calibrated threshold for a specified time, signaling a potential sensor fault or wiring issue.
