The Check Engine warning light will illuminate and you may notice that your vehicle has a hard time starting or running smoothly.

What does resistance of zero mean on crankshaft sensor?

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.

Where is the crankshaft position sensor located on a car?

The location of the crankshaft position sensor can vary from one vehicle to another. Obviously it must be close to the crankshaft, so it is most often located on the front underside of the engine. It can usually be found mounted to the timing cover. Sometimes it may be mounted at the rear or the side of the engine.

What to do if your crankshaft sensor is not working?

Issues with the crankshaft sensor can quickly lead to problems that affect the drivability of the vehicle. For this reason, if you suspect your crankshaft position sensor has an issue, have the vehicle inspected by a professional technician right away. They will be able to diagnose your car and replace your crankshaft position sensor if necessary.

What should the rpm reading be on a crankshaft sensor?

If the scanner gives a reading between 100 and 500 RPM, then it is working fine. Anything besides that reading indicates a problem with the crankshaft sensor whereas, zero reading suggests that the sensor has failed completely. If you don’t have access to a diagnostic scan tool, you can also test the sensor using a multimeter.

What kind of signal does a crank sensor produce?

This crank sensor is a 2 wire type and produces an AC voltage signal. The signal that the 3X (7X) crank sensor produces goes directly to the ignition control module and is critical for it to start activating spark and fuel injection.
