We purchased this bug a few weeks ago. We are getting a P0327 error code which is for #1 knock sensor. The car only has one knock sensor in the #2 position. There is no wiring for the #1. One mechanic said it only has one sensor. So why are we getting a code for a sensor that is not there. We have changed the #2 sensor and checked the wiring, still getting the code.

  1. P0327 Volkswagen – Knock Sensor 1 Circuit Low

    Possible causes
    – Faulty knock sensor
    – Knock sensor circuit poor electrical connection
    – Knock sensor harness is open or shorted
    – Faulty Engine Control Module (ECM)

    The P0327 code means that the Knock Sensor is not working properly. Problems with the knock sensor will not cause an engine performance problems. Replacing the knock sensor usually takes care of the problem.

    When is the code detected?
    An excessively low voltage from the sensor is sent to Engine Control Module (ECM)

    The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Engine Control Module (ECM).
