Mitsubishi Lan Se throttle position sensor failure.

Mitsubishi Lan Se Throttle Position Sensor Malfunction Idle Switch Short Circuit or Open Circuit. Improper installation and adjustment of the throttle position sensor causes the idle switch not to be turned off when the throttle is fully closed, or the idle switch is still turned off when the throttle has a certain opening. The sliding contact of the linear variable resistor is poor, and the throttle position sensor outputs during the process of the throttle valve from fully closed to fully open.
