I am trying to diagnose my cruise control issue. I pulled a code today which is P0608 - VSS Output.

Alll this is linked with the PCM and the TAC. The TAC sends out pulses to let the car know its speed in lamens terms. Does that mean this is what controls my speedo?
Is there seperate feed for the speedo from the TAC for the cruise?

I ask because everything seems to work for the TAC as far as radio turns up automatically at higher speeds, and speedo works just fine. Just my cruise doesn't work. Its like the car doesn't know what speed to kep it at when set.

I'm not sure if what I asked makes any sense. I was thinking there may be 2 speed control switches to have seperate control between speedo, and TAC, but it seems our car has one..

I hear of people changing out wires on the TAC, are they known to go bad?
