It is possible to accurately test the Crankshaft Position Sensor (commonly called the Crank Sensor) with just a Multimeter. In this article, I'll show you how. Now, the test I'm gonna' show you here is not a Resistance Test of the Crank Sensor since the Crank Sensor can not be tested in this way. Instead, I'm gonna' show you how to test the Crank Sensor in action by manually cranking the Engine and with your multimeter in Volts DC mode.
