This is one tested, used OEM Lexus driver rear control arm AFS headlight leveling sensor. This sensor fits all 2001-2006 Lexus LS430 models. 99% of the time when your AFS light starts rapidly blinking this sensor is the cause. Check your original sensor under the tan plastic cover with the 4 screws. You should find heavy rust and corrosion on the springs. Another problem area is the sensor plug and harness. The ground wire can become corroded and split in half. Inspect both the sensor and the wiring under the harness plug protector clip.
These sensors resolve code B2416 height control sensor malfunction assuming the sensor itself is bad. It could also be corroded wiring on the harness plug. The harness part number for the sensor that goes into the spare tire well is 82219-50030
New from the dealer these sensors retail for $745
These sensors are tested by hand on a test bench to ensure they are in working order.
