What is the detection method of engine throttle position sensor?

The detection method of the engine throttle position sensor is as follows: 1. Detect the power supply voltage and grounding Turn the ignition switch to the "OFF" position, unplug the sensor plug, and then turn the ignition switch to the "on" position. Measure the voltage between terminal 2 on the harness side of the sensor and the ground with a high impedance digital multimeter, which should be +5V. 2. Check the resistance and continuity of the sensor. Check the resistance value of the sensor. Turn the ignition switch to the "OFF" position, unplug the TPS plug and measure with a multimeter. 3. Detect the output voltage of the sensor, insert it into the sensor plug, turn the ignition switch to the "on" position, and measure the voltage with a high impedance digital multimeter.
