How to Check the Functioning of the Crankshaft Position Sensor

Model: Fiat Punto MK 2, 188 - Years 1999-2011
Part: Crankshaft position sensor

To verify the proper functioning of the temperature sensor, use a standard multimeter set to the ohm range (ohm X1 or X10). Connect the two probes of the multimeter to the sensor connector, which should be normally closed at room temperature, meaning the ohmmeter should indicate a value of a few ohms (needle at the bottom of the scale). Using a lighter flame or similar, heat the sensor head until the instrument indicates that the sensor has opened, meaning the needle should drop to zero (infinite ohms). Cool the sensor head until the instrument indicates closure (a few ohms).
