Featured Scion Knock Sensor Models

Getting annoyed by the loud knocks coming from under your Scion hood? This must be stopped but how would you do it? Probably, the thing that you have to do first is to have an idea what causes this knock sounds. It would then be easier to troubleshoot the problem if you know where and what causes such problem. But what actually is this knock sounds that seems to be persistent? The knocks that you can hear from your Scion's engine compartment are no other than the high frequency vibrations brought about by untimely burning of fuel inside the cylinders or simply called detonation.

There could be several reasons why detonation happens which includes high carbon deposits on the cylinders, spark plugs that heat up beyond engine's specifications, high temperature in the combustion chamber, and premature sparks. But the ironic thing is that your Scion engine performs at its best when it is operating almost in level with the detonation limit. It is indeed a critical condition but definitely you would not want to compromise the powerful performance of your engine. So, to allow your Scion engine to work at its best amidst the threat of reaching the detonation point is to make use of the Scion knock sensor. A Scion knock sensor is a piezoelectric sensor or accelerator that is attached to the engine and acts as the detector of high frequency vibration caused by detonation.

How can the Scion knock sensor prevent detonation to cause engine problem? The piezoelectric element that makes up the Scion knock sensor generates voltage whenever it detects vibrations. As soon as detonation is detected, the Scion knock sensor sends a voltage signal to the engine management computer which will cause to disable the spark timing to avoid further detonation. A reliable and dependable Scion knock sensor is an effective contributor to achieve optimum engine performance. Aside from this, the Scion knock sensor also protects the engine from being damaged due to the harmful effects of detonation.

Another good thing about the Scion knock sensor is that it is not a component that is frequently replaced. The Scion knock sensor seldom fails but of course it is still best maintain it properly to prevent engine damage. But in the event that your knock sensor is malfunctioning, have it replaced the soonest possible time. For your knock sensor replacement needs, visit us here at Parts Train.
