How often should you change crank sensor?

There is no definitive answer to this question as the frequency with which a crank sensor should be changed will vary depending on the make and model of the vehicle, as well as the driving conditions and the age of the sensor. However, as a general rule of thumb, it is recommended that crank sensors be changed every 60,000 to 100,000 miles. If you are experiencing any symptoms that could be indicative of a faulty crank sensor, such as engine stalling or misfiring, it is best to have the sensor checked by a qualified mechanic.
