Best to you.

Could be a bad control module ground ,but it could be a lot of thing's . Traction control is a strategy programmed into the ABS - anti-lock brake system . Could be any number of sensors or wiring issues . Taking the vehicle an having a full system scan (check codes + live data ) of all the modules on the vehicle . Not autozone or advance etc...

Do you know anything about ECM five volt reference circuit's ?
DTC P0641: 5-Volt Reference 1 Circuit
The engine control module (ECM) has 3 internal 5-volt reference busses called 5-volt reference 1, 5-volt reference 2, and 5-volt reference 3. Each reference bus provides 5-volt reference circuits for more than one sensor. Therefore, a fault condition on one 5-volt reference circuit will affect the other 5-volt reference circuits connected to that reference bus. The ECM monitors the voltage on the 5-volt reference busses.

The 5-volt reference 1 bus provides 5 volts to the following sensors:
• The manifold absolute pressure (MAP) sensor
• The clutch apply sensor
• The fuel rail sensor
• The fuel tank pressure (FTP) sensor
• The intake air pressure and temperature sensor

You have a shorted sensor more then likely or wiring problem . Suggest you watch this video .
How to check the 5v reference circuit for short to ground Cadillac

Take it to a shop. Don't fool with it. It has to do with the traction control.

traction control will not cause starting issues read check engine light or security

Has it done this since new? The computer has a built in Rev limiter, its job is to prevent damaging the engine from high RPMs.

Attention: This bulletin only applies to vehicle equipped with automatic transmission.

traction control should stay on and it should be a button on the dash somewhere (not sure where, my cobalt doesnt have one) but if it got shut off at some point its probibly just telling you its off becuase other than racing theres no reason to shut Traction Control off.

traction control is controlled by a button on the dash, the only time the TC light comes on is when its shut off, indicating that you do not have traction control. try locating the button and pushing it and see if that fixes the problem, if not there is something wrong in the tc circuit (such as a wheel speed sensor) and would need further diagnosis.
