Are you often bothered by the loud knocks you hear from the engine compartment of your vehicle? Oftentimes, they are caused by the premature burning of fuel inside the cylinders of the engine or detonation that caused the high frequency vibrations. On the other hand, detonations can also be the caused by other factors. Developing carbon deposits on the cylinder head, advanced spark timing, overheated spark plugs, and high combustion temperature are among the common causes of detonation. The high frequency voltage or 'knocks' on the engine will result to inefficient engine operation. For this matter, the Honda CR-V knock sensor was developed, primarily intended to sense the uneven burning of fuel and irregular vibrations or 'knocking' in Honda CR-Vs.

The Honda CR-V knock sensor is located in the engine which consists of an electric coil situated around two ceramic rods and having a magnet in the center. When engine vibration occurs, the ceramic rod vibrates and disturbs the electric coil's magnetic field and changes the flow of current traversing through the coil as well. A computer system is used to analyze the situation and determines the cause of the vibration for necessary changes.

The development of knock sensors is vital in the efficiency of the engine. The engine is able to produce more power by operating near the detonation limit, which in reality is found true in all engines due to the optimized process of power production. This, however, wouldn't be possible without the employment of knock sensors. The knock sensor's piezoelectric component generates voltage when it comes in contact with a specific amount of voltage that may cause detonation. To avoid detonation, the sensor retards the spark timing slightly.

In general, your Honda CR-V knock sensor is responsible for two purposes. One is that it offers optimized engine performance. The second is, preventing possible detonation that can cause serious problems to the engine. Basically, knock sensors are rarely subjected to repairs and replacement and should last for the life of your vehicle. But still, proper maintenance and inspection should be observed.

However, there are some cases where your Honda CR-V knock sensor gets damaged. Operating the engine with fuel having higher instability or lower octane ratings other than the needed is the common cause of knock sensor failure. This however can still be prevented, but in cases that it is already beyond repair, always seek for replacement parts immediately. Here at Parts Train, you can rely on with the kind of replacement Honda CR-V knock sensor stocked. Parts Train offers them in different applications, depending on the configuration of your Honda CR-V engine.
