ABS uses sensors and computers to sense what?

ABS uses sensors and computers to sense what?

• A. Potential wheel lockup
• B. Engine misfire
• C. Tire pressure changes
• D. Road surface condition

Answer: (A)

ABS detects when a wheel is about to stop rotating (lock up) by monitoring each wheel’s speed with sensors and a computer. If the system sees a wheel decelerating too quickly compared with the others, it briefly releases and then reapplies braking pressure to that wheel. This prevents lockup, keeps steering control, and helps maintain stability during hard braking. The other options aren’t what ABS monitors: engine misfire, tire pressure changes, and road surface condition are handled by different systems or sensors.
