Technical Crank, no start, no spark, no DTCs

Back in 2019, I bought this 2001 1.2 8V sensor from luke77. There are 3 wires but one is just a shielding wire. The only wires going to the sensor are the wires which have the resistance of 1238 ohms. This sensor however seems much less able to produce a voltage than my 1.2 16V 2 wire sensor. I think the problem is the sensor has lost some of its magnetism so a ferrous object passing thru the magnetic field creates less of a disturbance to create electricity. When I change the oil I will compare the magnetism with the one on my car

The change in magnetic field when ferrous metal passes by induces a small voltage in the coil. Over time and use the magnetic field reduces and so the induced voltage reduces. Loss of magnetism can be a cause of failure.
