Chevrolet Avalanche Knock Sensor

Chevrolet Avalanche vehicles contain a Knock Sensor that is highly useful in regulating engine performance especially in determining engine knock as a result of a wrong ignition timing. This device sends signals to PCM whereby PCM can regulate ignition timing with a view of reducing incidence of detonation. Usually, knock sensor is piezoelectric, transforming the vibrations into the electric signals and analyzing the pressure spikes associated with knocking. Years of Chevrolet Avalanche have employed improved knock sensor technology application especially in terms of the engine performance concentrating on various conditions of fuel quality and temperature. The system is able to change the ignition map of each cylinder and, in some cases, to control boost pressure. This puts the engine into optimal performance while at the same time it protects the engine from considerable damage when fuel grades below the recommended octane rating are used. The knock sensor is used in the vehicle for purposes of ensuring that the vehicle does not suffer from any loss of performance or durability.
