Your car’s crankshaft sensor is a critical component that plays a vital role in the proper functioning of your engine. However, this sensitive electronic device can be susceptible to damage from various factors. Understanding the common causes of crankshaft sensor failure is essential to preventing costly repairs and ensuring your vehicle runs smoothly.
Excessive Heat
One of the primary culprits of crankshaft sensor damage is the excessive build-up of heat in the engine. The sensor’s housing is typically made of plastic, which can melt or degrade when exposed to high temperatures. This can happen if you’ve been pushing your engine to its limits, if the engine has recently overheated, or if you live in a hot climate. The melting of the plastic housing can leave the sensor exposed and vulnerable to dirt, debris, and other contaminants, causing it to malfunction.
Electrical Problems
Another common cause of crankshaft sensor issues is electrical problems. Loose, worn-out, or damaged wiring can disrupt the signals sent to and from the sensor, causing it to malfunction. While the sensor itself may not be the root cause of the problem, the resulting electrical issues can lead to sensor failure and engine problems.
