sorry I have some experience on F and M series but none on I

what I would suggest is to ohm or replace the speed sensor. ohm spec I don't have but you should be able to compare it to another sensor that is similar. also make sure that the ring the sensor uses for reference isn't loose on the shaft. I will opt out and allow another expert that has more time on these machines to pick it up
