code p 2176 refers to throttle actuator control(TAC) system--idle position not learned ===causes basic setting not carried out
code p 1795 is CAN bus--throttle body position
code p 1780 is park/neutral position (PNP) switch circuit engine torque signal circuit
code p 1779 is engine torque delivered to TCM signal
go google and type in cadillac fault codes and find a site that has all the codes listed

When i push the gas pedal on mhy 2004 cadillac cts it feels spongy and wont go


Your dts uses drive by wire. The gas pedal is actually an electrical switch connected to the engine computer which then actuate a throttle body motor which causes the car to speed up or slow down. If you mean the car won't acceleration then the throttle actuator is probably going out, this is common and you replace the throttle body assembly as the actuator is sealed onto it. Had the same problem with my 04 srx (which is mechanically the same as a cts). If you have a check engine light on (and you should) get the codes read first as there are a few other problems that can cause throttle problems, however they are less likely the cause.

I have a 2003 Cadillac CTS. It continues to go into reduced power mode. How do I correct that.


Are you getting a ENGINE POWER REDUCED message ? Is the check engine light on ?
Reduced Engine Power Mode
Throttle Actuator Control (TAC) System
electronic throttle control .
When the ECM detects a condition with the TAC system the ECM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
?€¢
Limited torque


?€¢
Limited range of throttle movement


?€¢
Engine OFF


Your going to need to take this to a ASE certified repair shop or the dealer , you probably don't have the diagnostic tools to trouble shoot this problem.

When changing the tps in a 2003 cadillac cts do I have to change the whole throttle body or can I just replace the throttle control sensor?


Yes but i dont think thats your problum. i bet you its just the contacts that plug in the throttle body. they dont fit well it happends alot with the 2003 cts you can fix it by un pluging it putting a dent in the back of all 6 contacts. i used a dart tip to do it. then usr some cleener on them you should be good.
