ABS wheel speed sensor Part numbers: 9661738680, 4545F4, 454599, 4545A0 Product overview This ABS wheel speed sensor measures wheel rotation and provides the wheel speed signal used by anti lock braking, electronic stability and traction control systems. It is a direct replacement for vehicles and systems using part numbers 9661738680, 4545F4, 454599, or 4545A0. Key benefits Restores reliable wheel speed signals so vehicle safety systems receive accurate input. Reduces diagnostic time by providing a directfit replacement for the listed part numbers. Durable design resists road contamination and vibration to maintain consistent performance. Simplifies installation with an OEstyle connector and mounting interface designed to match original fit and orientation. What this sensor does Detects wheel rotational speed and converts it to an electrical signal for the ABS and related systems. Works as a replacement component where the original sensor is worn, damaged, or malfunctioning. Maintains signal integrity across normal operating speeds for accurate system response. Compatibility and fit Compatible with vehicles and ABS modules that use part numbers 9661738680, 4545F4, 454599, or 4545A0. Intended as a direct replacement part for the listed reference numbers to ensure correct fit and alignment. Confirm compatibility by matching the vehicle part number before ordering. Key attributes Function: Wheel speed detection for ABS, stability control, and traction systems. Fit: Compact, OEstyle dimensions and mounting for direct replacement of the listed part numbers. Construction: Robust housing and sealed electrical connector designed for exposure to road conditions. Performance: Stable, repeatable signal output across vehicle speed range to support system diagnostics and operation. Use scenarios a failed sensor after an ABS warning light appears to restore accurate wheel speed input. Install during brake or suspension repairs when the old sensor is corroded or physically damaged. Fit the sensor on a vehicle used in mixed driving conditions where previous sensors showed intermittent signals due to contamination. Installation notes Designed for plugandplay replacement where compatible. After installation, clear fault codes or run a system check with a diagnostic tool if required by the vehicle. This ABS wheel speed sensor is supplied to match the listed part numbers 9661738680, 4545F4, 454599, and 4545A0 and to provide a reliable replacement option for vehicles that require those references.
