I have got 2002 audi a4 2.0 b6 model. Where can i locate my transmission output speed sensor in the car

Does your versa have automatic transmission or CVT transaxle Makes a difference

The output speed sensor on a 2014 Ford F150 XLT is typically located on the transmission tailshaft or the rear of the transmission case. It is used to measure the rotational speed of the transmission output shaft and send a signal to the vehicle's powertrain control module (PCM) indicating the transmission gear ratio.
I would recommend checking the vehicle's service manual for a more specific location and a diagram of the sensor, as the location and installation may vary depending on the specific transmission model and options your Ford F150 XLT has.
The output speed sensor is typically a small, cylindrical sensor that is mounted to the transmission case. It is connected to the PCM via a harness and may be located near the transmission oil pan or near the output shaft.
If you're unsure of its location or have trouble finding it, a professional mechanic will be able to locate and diagnose any issues with the output speed sensor.

Have you any idea of how many models and variant BMW have made in the year 2002?

Google

2002 BMW (model) output speed sensor location

and you will get this, but tailored to your particular mystery model.

Hope this helps

are you referring to range sensor? speed sensor? input or output speed sensors? park neutral switch?

Hi I'm Peter your code P0720 Output Speed Sensor Circuit Malfunction This diagnostic trouble code (DTC) is a generic OBD-II powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may vary depending on the model.
On electronically controlled transmissions, the Output Shaft Speed Sensor (OSS) is located on the end of the transmission before the drive axles or driveshaft to read the speed of the output shaft which may be used to determine shift scheduling, torque converter engagement schedule and Electronic Pressure Control (EPC) inside the transmission. The Powertrain control module / Engine control module (PCM/ECM) has determined there is a malfunction with the OSS sensor. The PCM/ECM may substitute values based on other sensors to determine shift timing, torque converter operation and EPC pressure if the OSS sensor information is unavailable. The OSS sensor is also commonly used for the speedometer. Note: On some vehicles, the OSS sensor is inline with the Transmission Fluid Temperature (TFT) sensor, if there is a failure with the TFT sensor or associated wiring, the OSS sensor may malfunction as well. If there is another code associated with the TFT sensor as well as the OSS sensor, suspect a possible problem with either sensor, or the wiring in between

where the output shaft enters the transmission, around there

There is an input & an output speed sensor. There are also a couple of different transmissions as well. Wish the pictures were more clearer or more detailed but this was all I had to work with. The first picture is the location of the input one on both transmissions and of course the second picture would be the output sensors. Hope this at least gets you in the general area of the locations.

Speed sensor as in transmission like VSS Audi doesnt use on or RPM sensor as in the engine, Or wheel sensor for ABS Audi does use it is it for transmission or engine of wheel speed for ABS

Mounted on transmission
