Code P0221, Throttle Position code EPC light and check engine?

Hello. I own the vehicle listed above with a 2.0 turbo. Unfortunately, I’ve had lots of mechanical and electrical problems with the car. I’ve repaired just about everything and am down to the final code I want to fix. I’m getting a P0221 throttle position code, have cleared it for testing, but it comes back. I purchased the sensor that goes on the intake manifold but am also thinking the throttle body should come off for a full clean. Has anyone else tried to tackle this on these cars before? It would be my first time so I’m trying to get as much info as possible before beginning. Any help is much appreciated. Thanks, Mike
