94 Cadillac Deville error code???

[Mike55]

I have a 94 Cadillac Deville. The "service vehicle soon" and " Service ride control " comes on. I get an error code P091. I noticed yesterday that the cruse control doesn't work. I haven't check the fuse for the cruse yet.

My question is and I have looked for it in the manual what is a ride control and where is it? Also I don't see the error code in the manual PO91 any ideas what it is and how to resolve it?

Thanks for any help

P091 (E091) .................. PRNDL Switch Problem (transaxle range switch problem)

My guess is the cruise and the transaxle switch problem is related, you can probably include ride control in there too. I am not positive, but ride control is probably anything to do with the trans, axles or suspension, but that is just a guess.
