What It Does Knock Sensors Do Two Jobs Severe knock sounds like someone banging on a door. Mild knock reduces power, wastes fuel and increases emissions. Severe knock can destroy internal engine parts including the pistons, connecting rods, exhaust valves, head gaskets and spark plugs. Knock occurs when the air-fuel mixture doesn’t burn smoothly or is ignited too soon. Knock can be caused by “hot spots” in the cylinder, such as carbon deposits or spark plugs that are too hot for the engine, or high combustion chamber temperatures. Knock sensors play a dual role on OBD-II engines. Like other sensors, knock sensors monitor engine operation to optimize performance. In addition, knock sensors protect the engine against power-robbing, and potentially destructive, engine 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.
