I replaced the left track speed sensor and now F3N1 code comes up. anyone know what to do next?
What were the steps that led to replacing left sensor? F3N1 is right side speed sensor circuit fault. You can plug the left harness into right harness and see if code changes that will verify if issue is in sensor or harness. Sometimes you can get away without calibrating machine for a speed sensor. The possibility is there to open a large can of worms depending on the age of the machine. May need to replace both speed sensors, I've run into that a couple of times.
