P0502 Chevrolet -

Question

I have a 2001 Silverado 5.3 4wd and the t-case was broke and the guy swapped it out and now the speedo doesn't work and it doesn't shift in auto but I can shift manually 1st and 2nd. He said he changed all the speed sensors. How do I know if the connectors are plugged into the right sensors? Any tips or tricks would be greatly appreciated.

Answer 1

P0502 Vehicle speed sensor low input

There are 2 vehicle speed sensor located near the VSS .clear the code and leave one of the sensor disconnected, this would identify your sensor as it set a code. from there you can make the corrections
