Information
Speed sensor plays a vital role in your vehicle’s engine management system. It continuously monitors the crankshaft’s speed and position, sending accurate signals to the ECU. Without this data, the engine cannot control ignition timing or fuel injection correctly, leading to poor performance or even a complete no-start condition.

Diagram ref no 19
Primary Function:
Detects crankshaft position and rotational speed, ensuring the ECU can maintain precise ignition timing, efficient fuel delivery, and smooth engine operation.
When to Replace:
• Engine cranks but does not start, or struggles to fire up
• Intermittent stalling, rough idle, or sudden loss of power while driving
• Check Engine Light with diagnostic codes related to crankshaft/speed sensor faults
• Irregular ignition or fuel injection timing causing misfires or poor acceleration.

Information
Gearbox speed sensor.
The gearbox speed sensor detects the rotational speed of the gearbox output shaft and provides the necessary data to the engine control module, gearbox electronics and dashboard gauges.
Fits:
Porsche 981 / 982 (718) Boxster / S 2012>> (Manual Models Only)
Porsche 981 / 982 (718) Cayman / S 2013>> (Manual Models Only)
Porsche 981 Boxster Spyder 3.8L 2016
Porsche 981 Cayman GT4 3.8L 2016
Porsche 982 (718) Spyder / Cayman GT4 4.0L 2019>> (Only For Gearbox Code G8225)
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.
