Yes, your tech is correct in this case.
TPS normally operates from 0.2v to 5.0V, low voltage = less fuel, 5V = wide open throttle and more fuel needed.
In case when throttle is closed or almost closed (depending on system) and TPS, due to its fault, sends higher than required signal/voltage to ECM, let's say 4.0V, fuel excess will flood your plugs = difficult or impossible to fire up. Keep in touch with this good tech.
