Why is the check engine light on along with the TC symbol and a message that says engine power reduced?

"TC" symbol means "traction control", in other words it's trying

to keep you from slipping when you try to go. If that light is

constantly on, and the check engine light is on, it's PROBABLY

telling you that there is something wrong with the traction control

system, perhaps a faulty or disconnected wheel sensor.
