4Pcs ABS Wheel Speed Sensors — Front & Rear LH & RH Fits: 2007–2008 S500, 2008–2009 S500 Part numbers: 2215401217, 2219050401 Why you need this set Restores reliable wheelspeed input to the ABS, tractioncontrol and stability systems. Faulty sensors commonly trigger ABS warning lights, disable traction control, or cause inaccurate speed readings. This 4piece set replaces both front and rear sensors (left and right), allowing a complete service of the vehicle's wheelspeed sensing system in one . Directfit replacements that match the original sensor locations and electrical connections for straightforward installation. Key benefits Stops ABS/traction control warnings: failing sensors to clear error codes and restore normal ABS and stability system operation. One for a full : Includes front and rear, left and righthand sensors so all affected wheels can be serviced at once. Accurate speed signals: Helps maintain proper speedometer readings and system responsiveness for braking and stability controls. Key attributes Functionality: Wheel speed sensors for the vehicle ABS system; detect wheel rotational speed and transmit signals to vehicle control modules. Compatibility: Specifically listed for 2007–2008 S500 and 2008–2009 S500 models. Crossreferenced with part numbers 2215401217 and 2219050401. Fitment: Front and rear, lefthand and righthand positions included. Designed as replacements for the original sensors to match mount points and connector types. Performance: Engineered to provide consistent wheel speed feedback to ABS and vehicle electronics for safe braking and traction control performance. Construction: Manufactured to meet fitting and electrical connection requirements for direct replacement of the original sensors. Included in the package Four (4) ABS wheel speed sensors: Front LH, Front RH, Rear LH, Rear RH Sensors correspond to part numbers 2215401217 and 2219050401 Typical applications / use cases a failed sensor after an ABS warning light appears or diagnostic trouble codes indicate a wheelspeed sensor fault. a sensor damaged by road debris, accidents, or corrosion to restore traction control and ABS functionality. Preinspection maintenance to ensure ABS and speedometer operate correctly before a safety inspection or vehicle . Installation notes Designed as directfit replacements for the specified models and part numbers; basic automotive tools and routine mechanical skills are usually sufficient. Verify vehicle model year and part numbers before installation. If unsure, consult vehicle documentation or a professional technician to confirm fitment. This 4piece set provides a complete, compatible replacement solution for restoring reliable wheelspeed sensing on the specified S500 model years using part numbers 2215401217 and 2219050401.
