i have had my ABS light on, and after checking the codes it read my rr speed sensor. i bought a brand new speed sensor and installed it. Cleared the memory and light is still on. I took the car to a shop, they looked at it and said it's properly installed. What to do next? i want this light gone. When i check the codes it says RR speed sensor again.

 

Check the wiring from the RR sensor harness to the ABS control module.

 

Check the impedance in the new sensor and check the wiring to the ABS computer. The computer could be faulty.
