P0333 - Knock Sensor 2 Circuit High Input Bank 2. 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 Powertrain Control
Module or Electronic Control Module.
The code is triggered by an excessively high voltage from the sensor is sent to Powertrain Control Module or Electronic Control Module.
Possible Causes:
- Knock sensor circuit short to GND.
- Knock sensor circuit short to PWR.
- Knock sensor circuit open.
- Damaged knock sensor.
- Powertrain Control Module
Possible Solutions:
- Repair or resecure harness or connector
- Replaced knock sensor
