Knock Sensor: Description and Operation
Purpose
Purpose
Varying octane levels in gasoline can cause a detonation in an engine. This detonation is sometimes called a spark knock.
All of the engines use a Knock Sensor (KS) system with a knock sensor. The KS system reduces the spark knock in the engine. This allows the engine to
have maximum spark advance for improved driveability and fuel economy.
