This used OEM Porsche Engine Knock Sensor (99660612501) is a genuine part removed from a donor vehicle. It also replaces part numbers 99660612500 and 99660612100. This sensor detects engine detonation or pinging, sending a signal to the ECU to adjust ignition timing and prevent engine damage. A failing knock sensor can cause a check engine light, reduced power, or audible knocking under load. It fits the Porsche Cayenne with the 4.5L V8 engine, both naturally aspirated and turbocharged versions.
