Question regarding a replacement rim for 07 Ford Edge.?

One of my rims cracked while running into a pothole on the road. I'm planning on buying a replacement through ebay...my question is; do I need to buy a tire pressure sensor as well or is there a way of removing the one in the cracked rim and using it for the replacement one? Any other advice will be greatly appreciated

i would take it and gett it checked out at a shop

You will need to replace the valve stem seal if the wheel you purchase from eBay doesn't have a TPM Sensor valve stem fitted.

You can use the TPS that is on the cracked wheel unless it's damaged.
