Throttle Sensor - EML - P0221

So I've been having the christmas tree light up (the one where the ornaments are: DSC, ABS, BRAKE, EML) since I bought the car, but it's never been often enough for me to do anything about it. The lights would come on, sometimes with a P0221 error code, I would restart the car and keep driving. Well anyways, I was driving the other day and when I approached a stop sign I took the car out of gear and the tach needle started jumping sporadically all over the 500-2000 RPM range (NOT the limp home function!). This morning (cold engine) the lights came on along with the limp home function, and a P0221 code. I've looked around online to see what people were doing about it. Should I go straight to buying a new TPS? Has anyone else had this particular issue?

There is no TPS you could buy or change, if its the throttle giving errors, you need to change the whole throttle!

What do you mean by that? Or more to the point - what do you think I should I buy to fix it?

Your car is drive-by-wire and the accelerator position sensor is built into the accelerator pedal assembly.

You can view the accelerator pedal position and the throttle opening angle using INPA. This should give some insight as to whether either of these is the problem.
