Hi. I have a big issue on my truck. There is Chevy Tahoe 2003 4x2. ABS light is on, speedometer is not working, brake light is on and the transmission not shifting. I replace the code sensor P0502 , and the problem persists. What else what can I do?

Changing the sensor [which ever one ]probably wasnt the problem --your abs sensors since the light is on has failed either buy damage to sensor --harness--the hub is failing or rust debris is causing interference --check and examine the abs sensors harnesses and hubs for your problem P0502 Chevrolet Vehicle Speed Sensor Circuit Low Input

Off top of my head did you clear code after repair made, did you check fuses. Fuse would be a cheep easy fix but the link will provide additional info.
A fuse for a speed sensor in a 2000 ford in my brothers truck made it quit shifting, speedometer quit working.
