What are the detection steps of the throttle position sensor?

The throttle position sensor is also called throttle opening sensor or throttle switch. The detection steps of the throttle position sensor are as follows: 1. Read the data stream. When reading the data stream of TPS, it is necessary to slowly step on and release the accelerator pedal for observation to prevent the foot pad from blocking the opening or closing of the throttle valve, resulting in inaccurate detection data. 2. Measure the voltage of the throttle position sensor. The signal voltage of the throttle position sensor increases with the increase of throttle opening. When the throttle valve is fully open, its signal voltage is close to 5V, and when the throttle valve is closed (idling), its signal voltage is about 0.5v.3.. Test of unplugging the sensor connector. For an automobile equipped with an automatic transmission, if it is suspected that the abnormality of the throttle position sensor (TPS) will cause the shift impact of the automatic transmission, you can unplug the TPS for a test drive and use manual shift. If the upshift and downshift are free at this time, it shows that the normal problem of the mechanical part of the automatic transmission is that the control part TPS may have failed.
