Automotive Replacement Anti-Lock Brake Speed Sensors

Match the sensor to your vehicle by year, make, model, engine/transmission option, and the sensor mounting location (front/rear, left/right). Check the OEM part number or compare connector type, mounting bolt pattern, and wire length to ensure compatibility

OEM parts are made to the original specifications, while aftermarket sensors vary in quality, materials, and tolerances; many aftermarket options meet or exceed OEM performance, but verify fitment, warranty, and return policies before buying

Look for corrosion-resistant housings, sealed connectors, correct sensor tone ring compatibility, and a durable wiring harness; simple features like pre-installed mounting hardware and heat-shrink boots can improve longevity and installation ease

Replacement sensors commonly range from budget options under $50 to higher-quality units above that; prices vary by brand, vehicle application, and whether the sensor is sold singly or in pairs

Many sensors are user-serviceable with basic tools: jack and stands, socket set, Torx/Allen bits as needed, penetrating oil, and a multimeter; follow vehicle service manual steps and torque specs, and clear any diagnostic trouble codes after installation

Typical signs include an illuminated ABS or traction control warning light, erratic speedometer readings, reduced ABS function during braking, or intermittent loss of wheel speed signal on diagnostics

Use a multimeter to check resistance against the specification in the service manual and inspect for open/short; with the wheel raised, a diagnostic scanner or oscilloscope can verify an AC signal while spinning the wheel, and visually check for damaged wiring or contaminated sensor tips
