I say that the front sensors are working and the rear is not working. Replace the rear sensor.

Mr. Paul,
I changed the rear sensor as per your advice cost me $110 but the problem still there. The only difference is: before the lamp indicator start when i move to the front only, but now it starts when i move front or rear also.
Please i need your help....
