The video illustrates how to replace the engine RPM sensor of a generic car. The first step is to disconnect the negative terminal of the car battery. Now, locate the position of the RPM sensor, which in this Opel is located underneath the engine, directly below the starter motor.

Unscrew the bolts holding the sensor in place using the appropriate socket, and disconnect the electrical supply to the sensor. At this point, proceed to replace the old sensor with the new one, reversing the steps taken.
