        A:

        The code P0330 on your 1999 Lexus RX 300 is a knock sensor code. This BWD/Intermotor Sensor - Knock (Detonation) -part# S8648 is an exact fit for your vehicle. You would need to buy two knock sensors for your vehicle. For any further assistance, please visit your nearest Advance Auto store or call us directly at 1-877-ADVANCE (238-2623) and one of our representatives there would be more than happy to assist you.

    • Q:

      IF THE KNOCK SENSOR IS BAD, WILL IT CAUSE TRANSMISSION HESITATION?

        A:

        A knock sensor, which serves to warn of engine knock or pinging due to a bad air/fuel mixture, can go bad. Signs that the knock sensor is bad are a sluggish engine, poor fuel economy and slow acceleration. Mostly, the knock sensors do not fail entirely, but go soft and create false signals. You can check the knock sensor through an electrical harness.

        A:

        Yes. Knock (Detonation) Sensor. It picks up engine frequencies due to improper combustion and retards timing to the proper curve. When it fails, the vehicle’s performance suffers. "Detonation" or "Pinging" engine knocks as well as improper timing control. The crystal breaks down and can no longer create the proper signal.

        If it is pinging it is some internal part that is making the noise.
