Where is the BMW b48 electronic valve position sensor?

BMW B48 electronic valve position sensor is located on the throttle lever.

The principle of throttle position sensor is that throttle position sensor is actually a sliding rheostat. When you step on the accelerator, the idle signal line is disconnected and the sliding rheostat also rotates. The computer detects the voltage value, and the obtained data are compared and analyzed by the computer to control the basic fuel injection quantity.

There are three kinds of throttle position sensors: linear, switching and integrated. Throttle is easy to produce carbon deposit when it is used for a long time. When cleaning, you can remove the electronic throttle to clean the carbon deposit, but don't damage the electronic components on the throttle.
