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.

the light never comes on in normal driving. i was just checking voltage on secondary tps. yellow and white wire. was told should have 0.5 to about 4.5 from open to closed throttle. only has 0.5 open or closed if im doing it right. figuring secondary is towards the front of the car for the way they open

If that is correct, you have a wiring problem or there is an issue with the PCM.
