Let’s come and see what his problem exactly is and help him find out the solution.

I purchased the NT530 several weeks ago and tried to reset the adaptive values on the throttle body sensor. You know what? It’s so sad that I keep getting the same trouble code(P0121). 2016 Kia Optima had the code P0121-(Throttle position sensor). Why keep happening such a problem on my device? What am I supposed to do?

Technology engineer of Foxwellstore gave a satisfied solution as follows:
The reason causing this using problem of NT530 (P0121 Trouble Code) can be concluded as three aspects.
1. Some is wrong with the car’s throttle.
2. The accelerator pedal position sensor does not work normally.
3. Certain line fault of the accelerator pedal position sensor occurs.
If the car owner can check these causes of the problem by himself, very well then, just check them carefully and accordingly and you will fix it.
If not, it doesn’t matter at all. Go to the vehicle repair shop and let the professionals to check for you. You will certain fix it as well.
