Thats for the gas pedal sensor 2 it has a short to ground a open bad sensor bad wire etc. Do you have a scan tool that can read live data for gas pedal sensor number 2 and number one?

Morning, no I do not have a scan tool that can read live data, mine just gives the codes. And yes that was the only code that come up. After doing research I have found this could be a number of issues. From the gas pedal to throttle body and all in between lol, that's why i'm asking the pros. I cant wait to fix this issue

Thanx

The first thing the pros are going to do is see what the scan tool reads for the number 2 pedal position sensor. For that code it on only shows the pedal position sensor doesnt say anything about the throttle body that I see. It says there is a bad pedal position sensor or open short to ground etc.

Thats a loaded question thats called guessing and my answer would be if you want to gamble your money on a guess then you can. But I cant tell you yes replace it and it will fix your problem. Even if I had the car in front of me I would still have to start by seeing the pedal sensor readings. Also to see if the fault was active so I could start looking for the problem if it was active.I hear you on not having the scan tool and not wanting to buy one.I wish I had the luxury of not being able to not buy all the tools I have bought over the year's. Unfortunately the newer the car the more advanced they are the more computers they have etc. To read all those computers and to stay updated on the software on the scan tool plus buy the scan tool is expensive. Thats one reason its not cheap to bring your car in for repairs.
