Hey guys i could really use some help please. I recently had a code for the tps, don't remember the code for that tps but i went a head and replaced that part and now it is throwing a p2121 . Accelerater position pedal ..... performance something or other. This sounds like the same darn thing as the tps sensor. It has increased with the dead pedal at low rpm's. I have a flashpac downloader to clear the code right away. The p2121 will come back right as soon as it is cleared. #@$%!
