Technical Description
The knock sensor 2 circuit on bank 2 is experiencing a malfunction.
What does that mean?
This diagnostic trouble code (DTC) is a generic powertrain code that applies to OBD-II equipped vehicles. While it is a generic code, the specific repair steps may vary depending on the make and model of the vehicle.
A knock sensor is responsible for detecting when one or more cylinders in the engine are “knocking,” which occurs when the air/fuel mixture is exploding in a way that reduces power and can potentially damage the engine if it continues. The engine computer uses this information to adjust the engine’s performance and prevent knocking. If the knock sensor is not functioning properly and constantly indicating knocking, the engine computer may have adjusted the ignition timing. Knock sensors are typically installed in the engine block.
This P0330 code may appear intermittently or the Service Engine light may remain illuminated. Other DTC codes related to knock sensors include P0325.
