Check the wires and connector on the throttle body? The TPS is integral to the throttle body assembly, it is part of the throttle blade motor (thats not its technical name, just the only one I can come up with). Your engine doesn't use a accelorator cable, it is all electronic; Drive By Wire (DBW). When you mash the pedal, a little motor in the throttlebody opens the throttle blade and the TPS is part of it. I'm not sure if it can be replaced seperately, but my guess is no. The last time this code came up on one of these DBW engines, it was on my aunt's GMC Envoy and a rodent had chewed the wires at the throttlebody.
