There are a few usual suspects that will eliminate the majority of all problems.
The first is connections, connections, connections. It's worth going back over your solder joints, reheating them if necessary, and confirming that there are no shorts. Especially on any sensors that you've wired onto the 0.1" headers.
If you're getting funny readings out of your sensors, make sure the power supply to your XBee module is OK. The best way to do this is with a multimeter - set it to DC volts and confirm it reads 3.3V when you connect between GND and 3.3V, and whatever your power supply is when you connect between GND and V+.
Lastly, it's easy to configure the settings on your XBee module and then forget to save them. Then when you plug it back in, it reverts to its previous settings, behaving differently than you expect. Plug the XBee module in question back into the Make Controller and read back the settings to verify they're as you expect. If you need to, write them again and save them this time!
That should take care of the most common issues. Otherwise, please post to the forum for more help. Good luck!
