Abstract

OBD2 error code P0330 indicates a malfunction in the knock sensor circuit on bank 2 of your engine. The knock sensor detects engine knock or pinging and sends signals to the ECU to adjust timing, preventing serious engine damage. When this circuit fails, your engine may run poorly and could suffer internal damage if left unfixed.
