2019 Buick Lacrosse Essence 3.6l. Intermittingly I receive this code P2138. Googling tells me it could be the Throttle body position sensor or Accelerator pedal sensor. I can't seem to find just the TPS sensor on its own and seems I need to buy an entirely new Throttle Body. Has anyone run into this code and what has the most common fix? And can you just replace the TPS and not the entire throttle body? thanks
