Check operability of the sensor by resistance measurement. Check reliability of installation of the sensor then execute the following:
- remove the contact socket from the sensor;
- measure resistance of the sensor, having put multimeter wires to both contacts of the sensor;
- the multimeter should show 200±50 Ohm.
