OBD port fuse?

dc3843

So, was at discount tire today because for some reason, the TPS light came on on my dash shortly after tI drove the car off the other day with my new wheels installed. The used their sensor and all 4 TPS units are working and communicating. When they went to plug their unit into the OBDII port under the dash, its not powering up the unit. So they said it may be a fuse and to take it to the dealer. As I'm impatient, I'd like to replace this tonight if possible, but the dealer that sold me the car lost my owners manual. So I'm waiting on a new one from them, can someone tell me where I might find this fuse?

Also, discount tire did something with my key fob where it ended up in the parking lot and got run over. So I need a new one, theyre going to reimburse me for it. Anyone know a good dealer to purchase it from? It still works, but the car is brand new and I'm super anal with my cars. Thanks all.
