To get the proper signal from the throttle position sensor, the sensor basic position is indicated in the LCD
(DISPLAY) panel. The malfunction code is indicated in three digits. In front of the three digits, a line appears
in any of the position, upper, middle or lower line. If the indication is upper or lower line when engine rpm is
1 200 rpm, slightly turn the throttle position sensor and bring the line to middle.
In the normal condition, the throttle valve stop screw pushes throttle valves slightly, and indication point is
middle line.

Setting procedure:
1.Adjust the engine rpm to 1 200 rpm. (
2-15)
2.Stop the engine and connect the special tool (Mode select
switch) to the dealer mode coupler at the wiring harness.
3.If the throttle position sensor adjustment is necessary, loosen
the screws and turn the throttle position sensor and bring the
line to middle.
4.Then, tighten the screws to fix the throttle position sensor.
