The details to test crank sensor is as follows :---
Crankshaft Position (CKP) Sensor
TESTING
As with most all engine control sensors used in your vehicle, a thorough and proper test can only be performed by a qualified technician using a scan tool to read the data stream from the PCM. Following is a basic test to check for a 5 volt reference signal.
Turn the ignition key OFF .
Unplug the sensor electrical harness and check the terminals for corrosion and damage.
Check the sensor wiring harness wires for continuity and repair as necessary.
Attach the sensor harness making sure it is firmly engaged.
Using a Digital Volt Ohm Meter (DVOM) set on the DC scale, backprobe the sensor signal terminal (terminal A) with the positive lead of the meter and backprobe the sensor ground terminal (terminal B) with the negative lead of the meter.
Have an assistant crank the engine and observe the meter.
You should have approximately a 5 volt reference signal pulse. If not the sensor may be defective.
