Throttle Position Sensor

Hello all
I have come across a second hand set of Throttle Position Switch that is fairly good condition. I was just wondering if you need to, and how do you, clean the PCB tracks?
Regards
Peter

Hi Peter,

well just open the throttle sensor and polish all contacts well with isopropanol. Especially residuals between the combs of acceleration contact shall be closed. On the axis you find 2 tongues with contacts. Clean them by pulling through a stripe of paper between closed contacts.
