abs breaking system fault error

Hi friends! The abs light of my car has been flashing since yesterday. I looked at the cause of the pp2000 error, and the right ten wheel speed sensor showed a continuous fault. Anyway, I said I would clean the wheel and the sensor. I cleaned the sensor and replaced it. I deleted the error codes. I started the vehicle and for a while, when the vehicle came to the third gear, the abs light came on again, and then I stopped the car and fixed it in the third vut. I think the transmission got himself under protection. I read the error code again and the same fault. I searched for the malfunction code in the transmission, the speed sensor was writing that there was no signal. Is there any repair of the abs speed sensor or is it necessary to buy a new one? After clearing the foreign error code, ABS is active for a while. It sounded ticking from all sides, but when I went slowly the abs was activated when the brake was applied. When the abs light comes on, neither sound nor abs' s activity.

The sensor will change, my teacher has no choice but the 307s is a chronic problem.

For now, the problem is solved. I inserted the wheel and thoroughly cleaned the sensor and where the sensor was attached. If it fails again, it will no longer be renewed.
