How to measure Chang 'an Yuexiang throttle sensor and idle motor?

Pull off the plug on the throttle position sensor and turn on the ignition switch. Measure the voltage values between Vcc contact and idle contact and between Vcc and full throttle shock respectively, which should be 4.5-5.5V If it does not meet the requirements, the throttle position sensor is faulty. If the specified reading is not obtained on the throttle position sensor or the voltage signal is unstable, replace the sensor.
