P0330 Knock Sensor 2 Circuit Malfunction (Bank 2)
Technical Description
Knock Sensor 2 Circuit Malfunction (Bank 2)
What does that mean?
This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model.
A knock sensor tells the engine computer when one or more of your engine’s cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn’t knock. If your knock sensor wasn’t operating properly, so that it was always indicating a knock, the engine computer’s response may have been to change the ignition timing on your engine. Knock sensors generally bolt into or thread into the engine block.
This P0330 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325.
Symptoms

"Delete Error Code Permanently, Disable DTC Error Code Function for p0330 in the ECU"
In extreme cases, we even have the option to permanently remove the specific DTC p0330 and disable the function of the specific error code in the ECU. All other fault code functions will then continue to work to protect the engine. This is different from clearing an error code with a diagnostic device. We have the option to permanently remove the function of the specific error code, so that it never comes back. Also emergency running that occurs on the specific error code can be solved in most cases.
Of course we prefer to first try to solve the cause of the error code, but sometimes the only solution is to permanently disable the DTC function of p0330.
