The wheel‑speed ABS sensor — responsible for sending wheel-rotation data to the ABS module/ECU — can fail due to physical damage, accumulation of dirt/debris, corrosion, o r wiring/connector problems. In vehicles driven on rough o r unpaved roads common in many parts of Pakistan, debris, dust, mud can accumulate on sensors o r interfere with magnetic pickup, leading to failure.

Typical symptoms of a bad ABS / wheel‑speed sensor: ABS warning light on dashboard ABS malfunction wheels may lock during braking, o r ABS may not activate when it should inconsistent braking behavior possibly traction/stability systems o r other related functions may also degrade.

For diagnosis: after ABS light comes on — read fault codes from ABS module often via OBD o r ABS‑scanner to identify which wheel/sensor triggered error visually inspect sensor and wiring look for damage, looseness, corrosion, dirt o r debris, broken connectors check sensor alignment and mounting as wrong installation can cause errors.
