    When the conditions exist, knock faults typically will occur when operated at full power, such as during wide open throttle acceleration.

    Cummins ISL G The resistance of any wire to chassis ground should be K ohms or more, considered shorted to ground. The ECM will retard ignition timing and slightly de-rate the throttle.

    When the sensor detects engine knock, it drops the voltage down to a lower level; the ECM sees this as noise and de-rates accordingly. We have had over 15 turbos wastegates lock up after removing the turbo I had to beat it with a hammer to free it up.

    The knock circuit due to its higher voltage level bias voltage will not pick up any ground noise interference.
