2017 KIA CARENS Knock Sensor: High-Quality Replacement Part

Genuine MOBIS/GENUINE Knock Sensor (Part # 95930A4100) for your 2017 KIA CARENS. Enjoy guaranteed quality, a brand-new component, and the best price.

The engine knock sensor, also called a detonation sensor, plays a crucial role in maintaining optimal engine performance in your 2017 KIA CARENS. Its primary function is to detect pre-ignition—the uncontrolled combustion of the air-fuel mixture before the spark plug fires. This premature combustion can severely damage engine components, leading to potential issues such as cylinder wall pitting, piston damage, and ultimately, catastrophic engine failure. Common causes include excessive carbon buildup, generating localized hot spots, or incorrect spark timing, causing early ignition of the fuel-air mixture.

This crucial sensor utilizes a piezoelectric crystal (often quartz) to detect engine knock. When the characteristic vibrations associated with detonation occur, the crystal generates a small voltage signal (typically under 2.5V). This signal is transmitted to the Engine Control Unit (ECU), which then adjusts the ignition timing to mitigate the knock. The sensor’s crystal is precisely sized to resonate at the frequency range (6kHz-13kHz) of engine knock, maximizing its sensitivity to these harmful vibrations. This allows for precise and timely ECU intervention to prevent further damage.
