What is a Knock Sensor?
"Knocking" happens when the air-to-fuel mixture ignites prematurely. A knock sensor detects and identifies these knocking vibrations of the engine and then sends a signal to the ECU. It will then adjust the ignition timing and start the ignition as early as possible.
A faulty or broken knock sensor can cause the ECU to incorrectly adjust the ignition timing, resulting in poor engine performance. The engine will feel off, especially when carrying light or heavy loads.
