Description
Part Description
This ABS pump modulator assembly was removed from a 2003 Honda Accord EX equipped with a 2.4L engine. The part has been thoroughly inspected by our technicians and is currently on the shelf ready to ship. This OEM component shows normal wear consistent with its age but remains in good working condition.
The ABS pump modulator assembly is a critical safety component that controls brake pressure during anti-lock braking events. Common failure symptoms include ABS warning lights, loss of anti-lock function, or unusual brake pedal feel. When these units fail, replacement with a quality used OEM part like this one restores proper ABS operation at a fraction of the cost of a new unit.
