Rotation speed measurement at Transmission output
â–¶ How to fix
Check mounting position of the sensor (tolerance position, interspace). Check sensor. Change sensor.
What you'll see
No driver-visible symptom recorded.
System reaction
ANS operation limited. Limited driving operation. Transmission control unit switches into the operational status neutral, forced neutral or waiting for neutral. No or limited retarder function. No or limited reverse gear acceptance.
Diagnostic depth
Detection
Poor signal quality. The measured pulse durations/period durations vary more than allowed (no continuous signal available).
Possible cause
Torsional vibrations. Mounting position of the sensor not correct (tolerance position, pitch). Defective wheel of the pulse generator. Sensor defective.
