HQRP Knock Sensor. A vehicle knock sensor is a sensor screwed into the engine's block or cylinder head. It allows the engine to run with the ignition timing advanced as far as possible. The automobile's computer continues to advance the vehicle's timing until the knock sensor detects knock or detonation. After that the sensor sends the computer a signal to adjust the timing. This ensures greater FUEL ECONOMY and MORE POWER to get the most from your engine!
