Hello and welcome to JustAnswer!
Your truck has electronic throttle control. Inside the throttle body assembly there are actually two throttle position sensors, each working at a different voltage for redundancy and safety. The sensors are part of the throttle body and are only serviced with it. However, if one of the sensors had failed it would set a dedicated fault code for that since the powertrain control module is looking at the signals of both of the sensors and comparing them.
Replacing the TPS's isn't something you can do at all because they aren't serviceable. They're part of the throttle body.
No, there is no need to worry about the TPS's because there isn't a TPS code set.
