1982-99 Knock Sensor

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.

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 te st, pre-detonation or "ping", increased emission levels, low engine power.
