Speed Sensor - G50 Gearbox
Restore accurate vehicle speed measurement and reliable
speedometer operation with this OE Match Speed Sensor for Porsche
911 Carrera models equipped with the G50 gearbox from 1987-1989 and 1989 Porsche 911 turbo models.
Fits:
Mounted on the G50 transmission, the speed sensor monitors gearbox output shaft rotation and generates an electronic signal that is used by the vehicle's speedometer and associated control systems. As one of the key components within the vehicle speed monitoring system, a correctly functioning speed sensor is essential for accurate speed indication and proper operation of related electrical systems.
Manufactured to OE specifications, this direct replacement sensor provides dependable performance and factory-correct fitment for maintenance, fault diagnosis and restoration projects.
What Does the G50 Speed Sensor Do?
The speed sensor measures the rotational speed of the gearbox output shaft and converts this information into an electrical signal.
Its primary functions include:
- Monitoring vehicle road speed
- Operating the speedometer
- Providing vehicle speed information
- Supporting odometer functionality
- Assisting vehicle electrical systems
- Delivering accurate speed readings
- Maintaining factory instrumentation performance
Without a functioning speed sensor, the vehicle's speed indication system cannot operate correctly.
Why Do Speed Sensors Fail?
Speed sensors are exposed to heat, vibration, moisture and years of continuous operation.
Common causes of failure include:
- Internal electronic deterioration
- Heat-related ageing
- Wiring damage
- Corrosion of terminals
- Moisture ingress
- Gearbox contamination
- Physical impact damage
- Age-related component failure
As the sensor ages, signal quality can deteriorate, eventually leading to inaccurate readings or complete failure.
Symptoms of a Faulty Speed Sensor
Common warning signs include:
- Inoperative speedometer
- Erratic speedometer readings
- Intermittent speed display
- Odometer malfunction
- Speedometer needle fluctuation
- Electrical fault diagnosis issues
- Loss of vehicle speed signal
- Dashboard instrumentation faults
In many cases, the speedometer may work intermittently before complete sensor failure occurs.
When Should the Speed Sensor Be Replaced?
Replacement is recommended when:
Diagnosing
speedometer faults
Speed
readings become erratic
The
speedometer stops working
Replacing
damaged wiring
Carrying
out gearbox repairs
Performing
preventative maintenance
Restoring
a Porsche 911 or 911 turbo
Electrical
testing confirms sensor failure
Many Porsche specialists replace ageing sensors when undertaking transmission refurbishment work.
Why Replacement Matters
A functioning speed sensor is important for both safety and vehicle usability.
Benefits of replacement include:
- Accurate speedometer readings
- Reliable odometer operation
- Improved electrical system functionality
- Elimination of intermittent faults
- Enhanced driving confidence
- Reliable vehicle speed monitoring
- Improved restoration quality
- Factory-correct performance
For classic G50-equipped Porsche models, maintaining reliable instrumentation is an important part of preserving the driving experience.

OE Match crankshaft pulse sender, reference 94460611500, for selected Porsche 911, 924S, 928, 944 and 968 applications. Catalogued against the relevant Porsche reference, this engine electrical sensor is intended for installation in the specified DME engine-management systems.
What This Product Does
The pulse sender monitors crankshaft rotation and provides the engine control unit with the reference information needed to determine engine speed or position. Depending on the vehicle’s DME configuration, this signal supports the accurate control of ignition timing and fuel injection.
Functions
- Detects crankshaft rotation or a defined reference point
- Transmits an electrical pulse signal to the DME control unit
- Supports calculation of engine speed and crankshaft position
- Provides timing information for ignition and fuel-injection control
- Helps the engine-management system recognise that the engine is cranking
Technical Details
- Part reference: 94460611500
- Component descriptions: pulse sender, crankshaft position sensor, crank-angle sensor and speed reference sensor
- Earlier cross-references: 94460601500 and 94460601700
- The Porsche 944 and 924S engine-electrics catalogues specify two senders for applicable installations
- The Porsche 968 1992–1995 engine-electrics diagram specifies one pulse sender
- Quantity and sensor function vary by engine-management arrangement; confirm the vehicle specification before ordering
Symptoms of Fault
- Engine cranks but does not start
- Intermittent starting difficulty, particularly when the engine is hot
- Sudden stalling or cutting out while running
- Misfires, hesitation or an uneven idle caused by an unstable signal
- Tachometer signal dropping unexpectedly on applicable vehicles
- Stored crankshaft, reference-signal or engine-speed fault information
- Cracked cable insulation, heat damage or corrosion at the connector
Why Replacement Matters
A weak or missing pulse signal can prevent the DME from establishing the correct crankshaft reference. This may interrupt ignition and injection control, resulting in intermittent running faults or a complete no-start condition. Before replacing the sender, inspect its wiring, connector, mounting, sensor gap where applicable, battery condition and engine earth connections. Testing the signal during cranking can help distinguish a defective sender from a wiring or control-unit fault.

FAQs
- Why can a failed reference sender cause a no-start?
Without a valid crankshaft signal, the DME may be unable to time the ignition and fuel-injection events. - Why might the fault be intermittent?
Heat, vibration, ageing insulation or an internal electrical fault can cause the signal to disappear only under certain conditions. - Should the sensor be replaced from a fault code alone?
No. Inspect the connector and wiring, verify power and earth conditions, and test the sender signal where suitable diagnostic equipment is available. - How many senders are required?
The required quantity depends on the Porsche model and engine-management arrangement. Some 924S and 944 applications use two, while the supplied 968 diagram identifies one. - Does installation clearance matter?
Yes. The sensor must be correctly mounted, and the specified gap should be verified where the application uses an adjustable mounting arrangement.
