Knock Sensor 2 Circuit

The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Engine Control Module (ECM).

Cause:
Faulty Knock Sensor 2 Bank 2
Knock Sensor 2 Bank 2 circuit poor electrical connection
Knock Sensor 2 Bank 2 harness is open or shorted
Faulty Engine Control Module (ECM)

Symptoms:
Check engine light
Possible Lack/Loss of Power
