    Codes are meaningless without definitions. Always include definitions when posting codes.

    P0327 - Knock Sensor Circuit Low Voltage

    To answer your question, no. Your engine will be perfectly happy burning 87 octane under most driving conditions. Your engine has a very effective knock detection system. In the event detonation did occur, the PCM would compensate before you even knew it.

    What octane you use (even if it was lower than 87) has no effect on the knock sensor itself. The sensor is not an octane sensor, it never comes in contact with the gasoline. It is essentially a microphone, "listening" for the the particular frequency of vibration caused by detonation.

    Your code indicates a problem with the sensor, or a wiring/connector problem.
