Check engine error code 1597

Hello all,

So I have been searching and cannot seem to find a solution to fix this error code. It is P 1597 Speed control switch always too low. Does anyone have experience with this code? If so, any advice on how to fix it?

Thanks!

By the way I forgot to mention it is a 2001 Sahara automatic.

That code comes from the cruise control. Check the vacuum lines. And check/clean the electrical connector.
