With a TPS, you'll get a code usually when it sends a null value to the ECU when it's not supposed to. If it's sending data, it's really hard for a computer to figure out if the data is bad. Programmers usually put limits to data parameters so once they exceed set values the computer assumes it's an error. If the data remains within the set values the car will not report any problems even though the might exist.
