Code P0326 Hyundai Description
The P0326 Hyundai code indicates a problem with the Knock Sensor 1 Circuit on Bank 1. The knock sensor is responsible for detecting abnormal vibrations in the engine caused by detonation, or knocking. When the knock sensor detects these vibrations, it sends a signal to the engine control module (ECM) to adjust the ignition timing for optimal performance and fuel efficiency. A circuit range/performance issue means that the signal being sent by the knock sensor is outside the expected parameters, which can lead to poor engine performance, decreased fuel efficiency, and potential damage to the engine over time if not addressed.
