How can you check crank sensor with a omhmeter?

To check a crankshaft position sensor with an ohmmeter, first disconnect the sensor's electrical connector to prevent any interference. Set the ohmmeter to the resistance (ohm) setting and measure the resistance across the sensor's terminals. Compare the reading to the manufacturer's specifications; a significantly higher or lower resistance indicates a faulty sensor. If the resistance is within the specified range, the sensor is likely functioning properly.
