If the throttle body was actually bad, it seems that you would have some engine performance issues such as jerking, stalling, or limp mode.
When I checked my 2014 factory service manual for U0401, this is what I get:
U0401-IMPLAUSIBLE DATA RECEIVED FROM ECM/PCM
TIPM NOT CONFIGURED CORRECTLY
ABM CAN BUS DTCS
ALL WHEEL DRIVE (AWD) CONTROL MODULE
IF THERE ARE OTHER DTC'S, THEN IT GIVES DIAGNOSTIC PROCEDURES FOR THE FIRST 3. IF THERE ARE NO OTHER DTC'S, THEN IT RECOMMENDS: • Check the schematics as a guide, check the AWD Control Module pins, terminals, and connectors for corrosion, damage, or terminal push out. Check all power and ground circuits. If no problems, replace the AWD Control Module.
•Perform AWD Control Module VERIFICATION TEST.
