You're going to need a full diagnostic scan to find the problem.
I have did that and still haven't found the problem
I replaced both of them still didn't fix it can you ask #scotty question for me
DId you use OEM parts or aftermarket? Does your car require reprogramming or a a calibration procedure when replacing either of those components?
Scotty alone picks and chooses what topics he responds to, several each day. The rest are answered by the community. We have over 53,000 registered members and over 60,000 topics posted. It is not humanly possible for Scotty to answer them all.
Oem parts and did it the right way relearned it and all still haven't figured out what is wrong I want to ask scotty because literally no one can figure out what is wrong I have took it to several mechanics and garages

Note that there are special procedures required when replacing the pedal position sensor. (The "throttle position sensor" is part of the electronic throttle body actuator.)
You can also find diagnostic information for those codes specific to your vehicle:
read our FAQ ("Why do I have a warning light?")
Where is that at
the front page. Can't miss it.
Can you send me the link I still haven't found it
1- go to carkiller.com or click the 🏠 home link at the top of this page

3 - "Frequently Asked Questions (FAQ)" is the second link in that section
Use your browser's "Find" function , or the site search, if you still can't find it
I have did that and still haven't found the problem
You reported in another post (flagged as a duplicate) that you found codes P2127 and P2138. Those both refer to the throttle position sensor and/or throttle body. You will probably find those are the areas that need attention, see diagnostic information in the links below.

blindly replacing things rarely fixes anything and just empties your wallet. you need to follow the troubleshooting in the links Chuck gave you, in order to pinpoint the cause.
