The Knock Sensor in Buick Enclave vehicles is a featured element of the engine, which main function is to identify when the engine knock happens, as a result of inaccurate ignition timing. It transmits specific signals to the powertrain control module (PCM) to allow it to vary the ignition timing with a view of reducing extreme detonation. Commonly, knock sensor is piezoelectric that transforms the pressure variations to the electrical signals which are continuously analyzed in the search of pressure spikes that correspond to knocking. Buick Enclave models that exist in the market till date have applied complex knock sensor technology to achieve the premier overall performance regardless of the fuel quality and the ambient temperature. It can change ignition timing for every cylinder and control boost pressure which will help to provide a decent racy without harming the powerplant. This complex strategy helps the Enclave to run at optimum and for a long time especially when using low octane ratings fuel.
