congrats!
u see the dry solder point on top right?
just use soldering iron to solder again... settled.
Thank you so much for your guidance!
I re-soldered, everything working fine again!
Initially i sent this car to my mechanic friend to fix it, when i passed the car to him i even gave him the web detail that explain the issue come form this speed sensor. After a day, he called and insist issue is from meter board and need to change the whole set!

At the end he said cannot fix because cant find the new board again in the market
I took back the car, search this forum and follow the guidance, now the car fixed! Thanks for all the sifus here, especially bro Fireballs!
