ja, der Sensor kann oft Schaltrucke machen, wenn defekt, haben in letzter Zeit schon einige getauscht, siehe Seite 44 das Bild, und die Ohm auf Seite 45, auch fuer die anderen Ventile,
mess alle durch.

Output Speed Sensor 265 Ohms (72° F) = 22 Grad Celsius, ZF Teilnr. 0501 311 086. Kannst ja auch den von anderen Getriebe zum Vergleich Testen. Neueste Nummer scheint 0501-310-401 ZF zu sein. Die Ohm scheinen sich auch geaendert zu haben auf ~ 365, siehe diesen Thead

Selbst gemessen hatte ich 342 Ohm bei 30 Grad C an einem neuen Sensor.
das 4HP hat anstatt der 5HP nur einen speed sensor, 5HP haben 2, Eingang und Ausgang, das 4HP nimmt das Eingangssignal vom KW Sensor, Auszug aus der ZF Info
Excerpt from ZF info: Turbine Speed Sensor:
The Turbine Speed Sensor is used to provide input (turbine) shaft speed information to the TCM (EGS). The input shaft speed signal is used in conjunction with the output shaft speed signal to determine gear range and slip time information for processing in the TCM. Not all BMW transmissions use a turbine speed sensor. Some TCM’s use the TD (engine speed) signal to determine input shaft speed. All transmissions with the exception of the A5S325Z use an inductive type sensor which generates an AC analog signal. The A5S325Z currently uses a Hall Effect Turbine Speed Sensor which will send a digital square wave signal to the TCM.
4HP22/24 (EH), A4S310/270R: These transmissions do not use a Turbine Speed Sensor. The TD signal is used to determine input shaft speed. The TD signal is an output signal of the DME control unit.
A5S310Z, A5S325Z, A5S440Z, A5S560Z, A5S360/390R: These transmission use a turbine speed sensor. The TD signal is also used with the turbine speed signal to allow the TCM to monitor Torque Converter Clutch operation. The TCM can control torque converter clutch slippage and also monitor for faults.
Output Shaft Speed Sensor
The Output Shaft Speed Sensor is used to provide output shaft speed information to the TCM. The output shaft speed signal is used in conjunction with the turbine speed signal to provide the TCM with information on gear ranges and slip times.
All BMW electronic transmissions have an output shaft speed sensor. The output shaft speed sensor is an inductive type which will generate an AC analog signal to the TCM. The frequency and amplitude of the signal will increase as output shaft speed increases. The exact location of the output shaft speed sensor varies by transmission model.
