Knock Sensor (KS)
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.
Location: The Knock sensor is located on the engine block and in some applications under
the intake manifold.
Failure Symptoms: Malfunction Indicator Light (MIL) illumination, failed emission test,
pre-detonation or “ping”, increased emission levels, low engine power.
