Stukje gevonden over CPS testen op weerstand en voltage, maar je hebt er weinig aan zolang je de specificaties van Bosch niet weet.
You can remove the sensor, and then test the resistance. Attach one end of the multimeter to each wiring lead of the sensor. Resistance of zero means that the there is a short circuit. Infinite resistance means there is an open circuit. Either one of those readings indicates that the sensor is not working. For any other reading, check it against the manufacturer's specifications. If your reading is not close to the recommended resistance, then you should replace the sensor.
Another way to test the crankshaft sensor with a multimeter is by checking the output voltage with the engine cranking. You will need an assistant to do this. Be very careful around moving parts as you do this. Probe the wiring connectors and measure the output voltage in AC millivolts. Typically, this reading is around 200 millivolts, but this can vary from vehicle to vehicle. Check the manufacturer's specifications. If there is no output voltage, then, obviously, your sensor is not working.
