Where does the crankshaft sensor connect to?
The Crankshaft Position Sensor is attached to the engine block facing the timing rotor on the engine crankshaft. The sensor detects signals used by the engine ECU to calculate the crankshaft position, and the engine rotational speed.
Why are the crankshaft position sensor wires twisted and/or shielded?
The shielding via the grounded wire helps suppressing interferences on the VR sensor signal, a straight or twisted pair wire will not have enough shielding to avoid interferences.
What is shielded electrical wire?
Shielded cables are electrical cables that contain insulating conductors encased in a standard conductive layer. The shield can be made from strands of braided copper (or a similar metal), a spiral copper tape, or some other conducting polymer. Shielded cables are usually thicker and more rigid than unshielded cables.
How do I know if my VR sensor is polar?
Re: Vr sensor polarity Then take some piece of metal or perhaps a magnet and move it rapidly in front of the VR sensor. If you see a + voltage, your + is connected to + side. If you see a – swing, then the + is connected to the – side.

Why is my crankshaft position sensor not working?
Many times, a failing or inoperative sensor comes from a bad wire or connector. Make a visual inspection of the harness and connectors between the sensor and the PCM or ignition module. If necessary, check the air gap between the sensor tip and the rotor. Consult your vehicle repair manual for the specification.
What should the voltage be on a crankshaft sensor?
Touch the DMM red lead to each of the sensor wires on the harness connector you just unplugged. One of the wires should produce around 1.5 volts; otherwise, the sensor is not receiving a reference voltage, and needs to be fixed. Disable the fuel system by removing the fuel pump fuse or relay.
What should the CKP sensor read on a crankshaft?
Touch the DMM red lead to the red (power) wire on the harness connector. You may need to check the wiring diagram for your particular model, if the CKP sensor uses wires of different color to identify the ground, power and signal wires. Turn the ignition key to the On position. Your meter should read between 5 and 13 volts.
