2.0 code "Throttle Control Motor Lock fault"

[snowhite_intime]

Hi:
Can anyone help. We bought our daughter a 2001 VW New Beetle, less than a year after buying from another individual, the check engine light continues on and on. Newest code is: throttle control motor lock fault". We have already replaced the Mass air flow and oxygen sensors (plus the spark plugs, spark plug wires, battery and alternator). Any ideas on what to do? Also, daughter honked the horn and her "AIR BAG" indicator light came on. Anyone know what that problem could be? Thanks so much for any help.
