You have one crank sensor but it has a duplication circuit inside the sensor. Take a look at the info I attached about this for more info. This is why you have sensor A and B on the scan tool. What the scan tool is saying is the counts should be between 0 and 255 pulses per revolution. This is just a standard setting that the Autel tool uses. Your vehicle will do 18 pulses per revolution on sensor A and 3 on sensor B. Clearly this would be within the spec it is expecting to see. However, the tool is going to display this differently because it may count the pulses and display for multiple revolutions.
Do you have codes or any issues with the vehicle? The reason I ask, if you have no issues then this could just be a scan tool issue in the way it is reading this data. I would trust the vehicle to tell you if there is an issue rather then a generic scan tool like this. So if there are no issues with the vehicle then I suspect this is just a scan tool issue and the way it is reading the data for this vehicle.
Let me know and we can go from there.
