Gear Position & Speed Sensor Bundle – Porsche 911 PDK

The gear position sensor (often referred to as shift fork position sensor) is one of the most common issues with Porsche PDK transmissions. The sensor’s function is to provide the control unit with precise real-time positioning data of all four shift rods. The gearbox control unit continuously interfaces with the sensor pack to verify the accuracy of each gear shift.

If the sensor fails or malfunctions, the control unit loses this critical feedback and defaults to the current gear without executing further shifts. The following symptoms may appear:

• Vehicle enters limp mode or becomes undrivable
• Dashboard displays “Gearbox fault”
• Error codes: 1731, 1732, 1733, 1734 or 1735
• Diagnostic software reports “Shift rod N displacement sensor” failure

This sensor bundle also includes the speed sensor, which measures the clutch speed. The bundle is the ideal solution for issues with the Porsche PDK transmission related to the gear position sensor or the speed sensor. Many sources on the internet sell sensors of Chinese production, which unfortunately often prove to be prone to failure or have a short lifespan. The sensor bundle we offer originates from an international development project and includes components from various countries, including Germany. To ensure better compatibility and precise sensor readings, the sensor is offered in different versions, either for Boxster / Cayman or 911. Other manufacturers use the same sensor for all models, even though the transmissions differ slightly, which can cause problems with calibration and measurements. Another special feature is that the sensors are delivered as a plug & play solution with the connector included. Soldering or crimping the cables (as is the case with sensors from other suppliers) is not required, which also helps to minimize the error rate during installation.

Important: The installation of the sensor requires solid knowledge / skills and should only be carried out by qualified workshop personnel with access to compatible diagnostic software (e.g., PIWIS). After purchase, we will provide you with a detailed, illustrated installation guide. This sensor is suitable for 911 models only!
