I have a 92 camry dx and replaced the 14 inch dx wheel with 15 inch xle wheels. Does anybody know how to recalabrate to speedo? Is there a gear or sensor that i can replace?

is there a difference in the diameter of the tire? even though the rim size is different, maybe the 15" rims use a tire with a smaller sidewall.

If the XLE wheels still has 205/65R15 tires, your speedo will be off by 3%. When you're going 60 MPH, the speedo will be showing 61.8 MPH.

I wouldn't worry too much about it.

Next time you need tires, get 205/60R15s which have nearly the same diameter as what you started with. You'll be very very close to what you started with (at 60MPH, the speedo will show 59.8 MPH).

Check out this tire calculator.
