2008 Reduced engine power ?

Ok I am new to this forum Thank you in advanced with your well needed help. I have got a 2008 Corvette that I bought my wife and we have had it for about a month. It has 20,000 miles on it. It is now saying reduced engine power and also says service traction control. If I ran the codes and it says something about the the throttle and if I clear it then we can take off. But now it is coming on all the time. We are afraid to drive it anywhere. Thanks again,
Kevin

EXACTLY what code(s) did you get? "Throttle" could be several things.

Need those codes to fully understand possible reasons for reduced power. Or "limp" mode. Some issues automatically put car in limp mode to prevent damage or accidents.

P2135 Throttle / Pedal Position Sensor/Switch A/B Voltage Correlation. That is the 1st 1.

Thank you so much for the help. I have taken this to Chevy but they can not find out what it is. I will try anything. I bought this Actron scanner from auto zone just to clear them.
