3. Throttle Position Sensor Failure
The sensor is the throttle position signal transmission to the ECU, ECU signals and other signals using the
decision engine with real-time conditions. If the sensors malfunction, will affect the ignition timing and air-fuel
ratio mixture. At this point, the engine will show as not idling, acceleration, speed and so easy to increase or
even extinction.
Maintenance of the sensor removal is: pull the throttle position sensor wiring harness connector; check with a
multimeter between the conduction of the terminal situation. Throttle at idle position, the middle and upper part
of the terminal should turn; throttle is opened, the middle and upper part of the terminal should be disconnected.
Incompatible with the above results should be adjusted.
To ensure proper ignition timing and mixture air-fuel ratio, throttle position sensor must be adjusted
correctly. Is: start the engine, hand control throttle, the engine to maintain idle speed, loosen the two screws on
the sensor, throttle position sensor counter-clockwise rotation, while testing with a multimeter first to make the
middle and upper terminal disconnect , and then slowly turn the sensor clockwise direction, so that the middle and
upper terminal until the turn: The last two screws on the fixed sensor. Mainly the adjusted, should be replaced.
