A P1220 is a "Series Throttle Control Fault Detected"
Possible causes are:
Faulty Throttle Control Motor
Throttle Control Motor harness is open or shorted
Throttle Control Motor circuit poor electrical connection
Start by checking these things and let me know what you find. Also, let me know if the traction control is functioning when the vehicle is NOT spinning the tires.
