Most likely the air induction probably needs to be programmed into the ECM. But also you may have jounced a wire that has a connection to traction control and it is setting it off. Otherwise, you may have a standard trAction control problem that has to be addressed in the shop.

I have a 2001 Cadillac Deville with 105,000 miles. The ABS and Traction Control light stay on. What could be the problem? Could I reset the ABS and Traction Control light?

This is the Traction Control Warning light. Traction control is device added to the engine/gearbox sytem, and is designed to help minimise wheel spins when moving away, particularly on a slippery surface. When the system detects the wheels starting to slip and Traction control starts to cut in this warning light shows.

Traction control cannot do much to help in severe ice or snow though, so you can expect to see this light showing or flashing if the conditions are extreme.

If this light shows when the conditions are not extreme, stopping and restarting the engine will often reset it.

you probably push air into the ABS unit when getting your lines replace but the Traction Control light might be on because the system might use the wheel speed sensor on the ABS unit to enable the Traction Control.......

An ABS sensor DOES affect the traction control system. Traction control uses these sensors to determine if a wheel is losing traction. A bad sensor will cause both the ABS and TRACTION lights to come on.
The CHECK ENGINE light however is going to be a seperate problem.
