99% sure your dealer is correct that the TPS is not separately available and that you must purchase a new throttle body assembly.

I believe that the p/n is 12570790 and you can find it new online for around $300.

That's the way I understand it as well

Try a used part for cost savings?

Drive by wire.
Most automobiles use a throttle position sensor (TPS) to provide input to traction control, antilock brakes, fuel injection, and other systems, but use a cable to directly connect the pedal with the throttle.
An Electronic throttle control (ETC)-equipped vehicle has no such cable. Instead, the electronic control unit (ECU) determines the required throttle position by calculations from data measured by other sensors such as an accelerator pedal position sensor, engine speed sensor, vehicle speed sensor etc.
The absence of any mechanical linkage between the throttle pedal and the throttle body necessitates the use of a servomotor.
Integral to the servomotor (in this particular instance) is the TPS (Throttle Position Sensor).

Does your throttle stick in the vicinity if 1500 RPM when you push in your clutch - only to settle down after you stop. Mine does that from time to time. I have replaced the throttle body and the ECM in recent months - neither has fixed the issue. Solution seems to be alluding the techs.

Like dem Vettes

You don't necessarily need to replace the TPS. Did you test the TPS? A shop manual will provide the reference voltages. Here is something from You Tube on testing: http://www.youtube.com/watch?v=6eoH4...eature=related

I would think that part is still under the engine or emissions warranty. Later! Frank

A hanging throttle is almost certainly a tuning issue, typically the dashpot function.
