How to reset the position sensor on the Kymco Downtown

Model: Kymco Downtown 125
Part: Checks and maintenance

Video tutorial

Let's see how to recalibrate the position sensor on a Kymco Downtown, to solve the problem of irregular acceleration, unstable idle or loss of power. Make sure the emergency switch is in the "ON" position.

With the key still off, fully open the throttle, and turn on the ignition; keep the throttle open for eight seconds (count slowly). Now release the throttle and turn off the ignition.

This procedure teaches the ECU what the zero value (rest position) of the throttle is; this resolves those delivery problems caused by values ??outside the specification. Of course, it does not solve physical faults.
