Knock Sensor (KS)
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  illumination, failed emission test, 
pre-detonation or “ping”, increased emission levels, low engine power
