Welcome to VEXIQ and HEXBUGS
Sadly, that sensor is DEEP inside the engine area. You don’t need to take apart the entire truck but you will need to take the front apart. As I remember, taking the hood off and going that way was slightly easier than taking the bottom off.
In either direction you are looking at about 1/2 hour of disassembly/assembly time. I would take it apart, verify the the placement and then try it outside of the truck. That way if they decide you need a new sensor that you are not taking it apart AGAIN.
