Malibu M Series Knock Sensor - OEM Engine Detonation Sensor

Restore smooth, reliable performance in your Malibu M Series engine with this genuine Malibu Boats knock sensor. Designed to detect engine knock (detonation) and send a precise signal to the ECU, this sensor helps the engine maintain optimal timing for strong power, efficient operation, and added protection under load—especially important for watersports use.

• Application: Malibu M Series engines (verify fitment by engine/ECU requirements)
• Function: Detects abnormal combustion/knock to support accurate ignition timing control
• Connector: OE-style electrical plug for a secure, factory-style connection
• Construction: Compact round housing with integrated mounting fastener
• Brand/Vendor: Malibu Boats (OEM replacement)

Common symptoms of a failing knock sensor may include reduced power, inconsistent acceleration, check-engine/fault codes (where equipped), or timing-related performance issues. Replacing a worn or damaged sensor helps restore proper feedback to the engine management system.

Installation notes: Ensure the mounting surface is clean, align the sensor correctly (orientation mark), and torque to manufacturer specification. If you’re unsure about compatibility, confirm your engine model/year or reference your existing sensor before ordering.
