Throttle position sensor

Hi everyone,

First of all I'm from Greece and I own a black 2015 pcx 150.
I've been having an issue with my pcx nearly a year now that has really made me want to throw it of a cliff.
It appears mainly on very humid days and what happens is that when I turn the throttle quickly, when lets say i want to pass a car, the pcx stalls. If i release the throttle and turn it slowly then everything is fine.
My mechanic has checked several things and has also changed two harnesses but the issue remains.
From my own search I am 90% sure that the problem is the throttle position sensor.
My question is if this part is easy to find, if its expensive and whether I can replace it at home.

Any feedback would be really appreciated.

Has all codes been checked and computer scanned?

I took it to the shop several times and they checked for faults and even installed some updates that would solve the problem but nothing.
The feeling is exactly as described in the post whitenoise.
So I guess I will take it back to the shop and ask them to replace the TPS!
Will keep you updated if that solves the problem.


Thank you for your help.

What have you done besides changing harnesses?Have you checked the spark plug.The fuel pump and/ or fuel filter are possible culprits as well.
