Note
t Regarding fault code 00513:
t Additional signals can be generated by metal swarfs.
Signals may not be generated or be too weak and therefore not be detected due to a too
t
large distance of the sender to the sensor rotor or by a damaged sensor rotor.
t The signal routing can be irregular due to a loose sensor rotor (or loose sensor).
