I would just remove the TPS. Its more trouble and expense then its worth.
- put shifter on N, screw off shifter
- open up center console
- pull the whole heated seat module straight up, it will come up. disconnect
- you will be able to pull up the "back" part of the shift plate area (close to center console)
- once it's up, the only point holding it are two clips right below the radio
- pull the shift plate towards the back of the car and a bit angle up. jiggle a bit and it will come off
- once it's out, you will see the TPS unit right below the radio
- unplug BOTH plugs, one small on the right and one bigger one on the left
