The car will run without a TPS. You can replace just the TPS for under $50. Google or eBay "Omni Power TPS." You can make slots in the scews that are on the original TB and use a screwdriver to remove the old one. The new one, from Omni Power, will come with replacement screws. You just need to calibrate it. You can find out the steps by googling as well.
As an alternative, you can find another Honda TPS from a junkyard TB as well if that is easier.
