Knock Sensor Assembly

The Subaru 22060AA180 is a genuine OEM knock sensor assembly, engineered to precisely detect and report engine knock or detonation. This critical sensor plays a vital role in engine management systems by allowing the vehicle's computer to adjust ignition timing and fuel delivery to prevent engine damage and optimize performance. It operates with a specific base knock frequency of 5.68kHz, and its second harmonic frequency is 11.36kHz, allowing for accurate detection of abnormal combustion events. This knock sensor assembly is designed for a wide range of Subaru models, spanning from the 2011 to the 2025 model years. It is confirmed to fit vehicles such as the Subaru BRZ, Crosstrek, Forester, Impreza, Legacy, Outback, Tribeca, and WRX. While the fitment generally covers a broad spectrum of Subaru vehicles within this timeframe, it is always recommended to verify specific application details for your vehicle to ensure perfect compatibility. As a direct replacement part, the Subaru 22060AA180 knock sensor is intended to meet or exceed the original equipment manufacturer's specifications. Proper installation is key to its function, and while specific torque specifications are not provided in the source material, it's generally critical for knock sensor installation to adhere to manufacturer torque guidelines to ensure accurate readings and prevent damage to the sensor or engine block. A failing knock sensor can lead to a check engine light with codes like P0325 or P0328, potentially affecting timing advance and fuel economy, making timely replacement important for maintaining optimal engine performance.
