Description: Location: The Knock sensor is located on the engine block and in some applications under the intake manifold. The Knock sensor generates an AC voltage created from the frequency of poor combustion in the engines combustion chambers. A mechanical fault within the motor creating a rapping sound may create false signals from this sensor. Ignition timing and the air/fuel ratio are adjusted to compensate for this condition. Failure Symptoms: Malfunction Indicator Light (MIL) illumination, failed emission test, pre-detonation or “ping ”, increased emission levels, low engine power.
