This is the OEM Knock Sensor found on all 2011+ Nissan Juke's. This sensor acts as the ECU's "ears" and listens for detonation, also call spark knock or pre-ignition. When this is detected, the ECU pulls timing and adds fuel to prevent further detonation, preventing imminent damage. When the knock sensor fails symptoms often include CEL (Check Engine Light) Illumination, loss of power, etc.
