What is the detection method of throttle position sensor?

The following is the detection method of the throttle position sensor: 1. Detection of power supply voltage: unplug the connector plug on the throttle position sensor, turn on the ignition switch, and measure the voltage between the idle contact Vcc and the full throttle contact Vcc respectively, which should be 4.5-5.5V If it does not meet the requirements, check the ECU connection circuit. If the voltage value meets the requirements, check the resistance of the throttle potentiometer. 2. Resistance detection: unplug the throttle potentiometer and measure the resistance between Vcc and idle contact, which should be1.5 ~ 2.6kΩ; Measure the resistance between Vcc and VTH, which should be 0.75 ~1.3kΩ at idle speed. Slowly turn the throttle lever to the full open position, and the resistance value of the potentiometer should rise to the maximum value of 3.6kΩ. If any irregularities indicate that the throttle position sensor is faulty, replace it.
