Ford Knock Sensor

If you own Ford and want to keep it in top shape, choosing OEM Knock Sensor is a smart move. They are precisely engineered and follow strict factory standards.

Ford Knock Sensor cuts down the destructive engine knock within a short time, keeping its power and parts alive. Ford began with the radical assembly line of Henry that reduced the time spent on building and cut expenses for ordinary drivers. That lean mindset is still held by the company, which introduces EcoBoost motors that drink fuel but propel pickups, even over steep hills. SYNC also allows the occupants to bark voice commands on the music or maps without losing control and gluing eyes to the asphalt at highway speed. Ford Co-Pilot360 brakes its way out of danger, pops, and steers a lane back on the road before trouble arises. Electric F-150 Lightning carries loads without making a noise, so tailpipes will no longer belch smog along residential areas and parks that children use to breathe. Ford challenges technology in simplifying hard work but will not confuse the busy schedule of the driver. Knock Sensor transforms vibration into high-frequency voltage, which is read immediately by the powertrain brain, adjusting the spark angles before micro-explosions cause rod bearings to hammer or even melt the piston crowns during high load pulls. Ford adjusts Knock Sensor logic to allow the motor to drive near its detonation limit without incident. Knock Sensor also helps to eliminate the expensive premium fuel as it modulates the spark dynamically. Knock Sensor implies that drivers perceive power, not ping.
