Code P0325 2016 Chevrolet Silverado Description

The P0325 diagnostic trouble code (DTC) for a 2016 Chevrolet Silverado indicates a problem with the knock sensor circuit in bank 1. The knock sensor is a crucial component in the engine management system that detects abnormal combustion, often referred to as engine knocking or pinging. When the knock sensor detects these abnormal combustion events, it sends a signal to the engine control module (ECM) to adjust the ignition timing to prevent engine damage.
