What is a spark knock sensor?

Knock Sensor (KS) Detects Engine Spark Knock Engine spark knock may occur when; the engine is working hard under load, causing the (PCM) to retard timing. This reduces power a bit but, protects your engine against damage. However, if the knock sensor is not working, spark timing will not retard when it should.

When the spark plugs do not generate the adequate spark, the combustion of the air/fuel mixture becomes incomplete, leading to loss of engine power, and in the worst-case scenario, the engine will not run.

What causes a bad knock sensor?

The knock sensor detects abnormal combustion, known as spark knock, inside of the engine. Common causes of spark knock include low octane fuel, overly advanced ignition timing, abnormally high engine operating temperatures, and carbon buildup inside the engine’s combustion chambers.

What does a knock sensor on an engine do?

The knock sensor detects vibrations that come from a knock or an irregularity in combustion and send a signal to the engine control computer, which then adjusts timing to correct the knock. Bad knock sensor symptoms

What happens when you knock on your engine?

When this happens, there’s a tiny shockwave that occurs around that explosion (along with the normal detonation from the spark plug), which greatly increases the pressure in the cylinder. In extreme cases, knocking can result in catastrophic damage to the engine, including cavitation or even perforation of a piston crown.
