What This Product Does

The sender supplies the electrical speed signal used by the speedometer. It is a gearbox-related vehicle-speed component, rather than an engine reference or knock sensor; those components perform different monitoring tasks.

Functions

• Provides a pulse signal for vehicle-speed indication.
• Connects gearbox speed sensing with the speedometer system.

Technical Details

• Brand: Genuine Porsche.
• Application: G50 gearbox speed sensing.
• Supplied part references: 91160691001 and 91160691002.

Symptoms of Fault

Intermittent electrical behaviour, damaged cable insulation or corroded connections warrant investigation. Inspect the sender wiring and connectors before attributing a speedometer problem to the sensor itself.

Why Replacement Matters

A confirmed sender fault can interrupt the speed signal. Replacement addresses the defective component, but damaged wiring or poor connections must also be corrected. Matching the part to the specific G50 installation helps avoid compatibility problems.

FAQs

• Is this an engine-speed sensor?
  No. The supplied diagram identifies it as a pulse sender within the speedometer assembly.
• Does the Turbo listing cover every model year?
  The supplied fitment lists 1978-1989, while the diagram specifies 89- for this Turbo sender. Confirm the exact gearbox application before ordering.
• Should the sensor be replaced without testing?
  Check the wiring, connections and signal first. Similar electrical symptoms can have more than one cause.
