Model: 2009 Hyundai Sonata Fault Code: P0331 Posted: 2014-03-08 23:33

Where is the knock sensor located in a 2009 Hyundai Sonata? What are common causes of a P0331 fault code? Will replacing the knock sensor mask an underlying engine problem, or will the code persist if the issue remains unresolved? If my engine experiences actual knocking or detonation, what symptoms should I expect and how does it affect performance and fuel efficiency?
