Cruise Control Not Working

[EO's SHO]

My cruise control or speed control recently stopped working. I checked the fuse and its fine, my horn work fine. But, when I ran my codes I got a 452. Has anyone dealt with that before? I have a 93 ATX, 170K mi. Thanks.

Thanks I'll give it a try. Will doing this make my cruise control come back? I'm planning a trip to Chicago in a month and it will be nice to not have mash my foot down for 4 hours.

Be sure to check the obvious and see if the linkage is still attached to the TB.
