The Knock Sensor in Dodge Grand Caravan vehicles is a very significant device when it comes to car performance and functionality because it identifies engine knock, which is resulting from an improper ignition timing. Through its connection to the PCM, this device allows the PCM to advance the ignition time in order to reduce the excessive detonation. Usually the knock sensor is piezoelectric and measures vibrations in the engine head and provides signals indicating pressure rise and therefore knocking. Through the years, different models of the Grand Caravan have incorporated MDS with knock sensor that refines the change in the ignition timing and depending on the model, boost pressure as well. This provides the optimal operation of the engine while at the same time reducing on the damaging impact that the fuel can cause even if it is of low octane rating. The availability of the precise control of the time in individual cylinders also improves the car's flexibility of operating within various conditions of driving.
