Description

The pulse/speed reference sensor provides the engine electronics with crucial information about the speed and position of the rotating components. A defective sensor can cause symptoms such as rough idling, starting problems, misfires, or complete engine stalling. This sensor replaces the respective OE sensor in Porsche 964, 993, and 996 Turbo vehicles and restores correct signal acquisition for the engine management system.

Depending on the engine control unit (ECU) system, the pulse generator can be used as a crankshaft or camshaft sensor . From model year 1996 onwards, Porsche equipped knock sensors, temperature sensors, and speed sensors with improved connectors. If the earlier version in your vehicle was replaced or modified, an adapter kit for the connector may be required.
