What items should the throttle position sensor detect?

Detect items that should be detected by the throttle position sensor.

1. If it is an electronic throttle or a multi-line direct-acting throttle, you can read the fault code with a decoder or use a multimeter to check whether the voltage signal is grounded normally.

2. Direct-acting throttle, line 7, unplug the sensor plug, turn the ignition switch to the on position, turn the multimeter to the buzzer position, and connect the probe to pins 3 and 7. At this time, the multimeter will ring, but the throttle flap will not ring, so it can be judged that the idle signal line is good.

3. When the multimeter is set at 20V, the probe is connected to 1 and 2 pins, and the multimeter will display a voltage close to 12V, so it can be judged that the idle motor is in good condition. When the multimeter is set to 20V and the probes are connected to 4 and 7, the voltage of about 5V will be displayed. When the multimeter is turned to 20V, the probes can be connected to 5, 7, 8 and 7. Starting the engine will show a change between 0 and 5 V. ..

4. When detecting the linear output throttle position sensor, turn off the ignition switch, unplug the sensor plug, and measure the position of the potentiometer with the resistance of the multimeter. When testing, let the throttle opening gradually increase, and lap the multimeter between the moving contact plug and the original plug. The resistance value should decrease steadily with the increase of throttle opening. If it does not meet the requirements, it should be replaced.
