I had the car scanned at Autozone. It came back as the "throttle position sensor".

I have searched around on the net, and have not had much luck. I am trying to stay away from the "stealership".

Any suggestions?

have you tried autohausaz.com? great customer service and one of the best prices around!

I believe you are looking for "CPS- crank position sensor" - autohausz

Not the same thing! Other names for it are "fuel regeneration sensor" and "pedal value sensor." It's the drive-by-wire throttle module and has nothing to do with the CPS.

The TPS is part 80 on this picture:

It's discussed, and a photo is shown, in this thread:
