I have a 1996 S10 Blazer with 149,000 miles on it. Sometimes when I first start driving it won't shift. Also the ABS light comes on. I got a P0502 code (vehicle speed sensor low imput). This has happened a few times when I first start driving after the vehicle has been sitting for a day or so. After awhile the light goes off and it starts shifing fine. Any ideas as to what the problem is?
Thanks for your time.

Code 502 is low input from speed sensor.
Repair speed sensor or wiring.

Thanks. Will the speed sensor keep it from shifting and cause the ABS light to come on?
