what are common causes of getting a knock senor code off CEL?

 

KS = kansas. where i live (i am from CA, though )

 

hmm...think about what a "knock sensor" might do. It detects engine knock which is generally caused by lower-than-recommended octane fuel, but it could also be caused by a hot spot inside the cylinder.

^ yep. bad gas... use up what you got... get new gas. maybe need to reset ECU afterwards if it doesn't clear on it's own

 

A knock sensor code usuaally indicates a faulty knock sensor. Running too low of octane gasoline will not throw a CEL.
