Try disconnecting the battery for 10 mins and see what happens to the VSC light

Get an OBD2 scantool or take it to Autozone and have them to try and erase the code-double check all wiring harness and connectors for loose and damages

Check the wiring of the MAF sensor back to the computer for short and open circuit
