Technician A is correct because the Throttle Position Sensor (TPS) input is used by both the Powertrain Control Module (PCM) and the Transmission Control Module (TCM) to manage engine and transmission functions. Technician B is also correct because modern fly-by-wire systems often use multiple TPS sensors for redundancy and accuracy in reporting throttle position.
