Diagram ref no 11

This sensor monitors how fast the gearbox is turning and sends that data to the vehicle’s control systems. It helps the transmission and engine computer decide shift points, rev matches, speedometer readings, and in some cases limits or safety functions. Without an accurate signal, many systems can’t function correctly.

A faulty speed sensor can lead to incorrect or delayed speed readings, inconsistent shifting behaviour, or misreported speed on the dashboard. Over time, wear, contamination, or mechanical damage can degrade sensor performance. Replacing it restores precise transmission control, safer driving, and prevents further damage to related components like the gearbox ECU, shift linkage, or drive train.

Crankshaft Position Sensor. Porsche 958 Cayenne S/GTS/Turbo 4.8L / 970 Panamera 3.6L & 4.8L

9A7905381/2::1

Product Information

Crankshaft Position Sensor.
This sensor precisely monitors crankshaft rotation and relays vital timing data to the ECU. Built to withstand extreme heat and vibration, it ensures smooth engine operation, accurate ignition timing, and reliable power delivery.

Fits:
Porsche 958 4.8L Cayenne S / GTS / Turbo 2011 - 2017
Porsche 970 3.6L / 4.8L Panamera S / GTS / Turbo 2010 - 2016

Diagram ref no 13

This sensor tracks crankshaft rotation to identify piston position and engine speed, sending precise timing signals to the ignition and fuel systems. By doing so, it ensures smooth starts, efficient combustion, and consistent power delivery. It also supports key safety functions, including misfire detection and limp-mode protection.

A faulty crankshaft sensor can lead to hard starts, stalling, loss of power, or even engine shutdown. It may also trigger check-engine lights, misfires, and disrupt critical fuel and ignition timing. Replacing it ensures reliable performance, and helps prevent costly engine damage.

Common signs of a failing crankshaft sensor include hard starting or long cranking times, unexpected stalling, and rough idling or power loss while driving. You may also notice the check engine light triggered with related fault codes, misfires, or a drop in fuel efficiency.
