Can low octane fuel cause knock sensor code?
Running lower octane gas will not cause the knock sensor to go bad nor will it cause a CEL. Running lower octane gas will not cause the knock sensor to go bad nor will it cause a CEL.
What causes octane knock?
Knocking occurs when fuel burns unevenly in your engine’s cylinders. When cylinders have the correct balance of air and fuel, fuel will burn in small, regulated pockets instead of all at once. Engine knocking happens when fuel burns unevenly and those shocks go off at the wrong time.

Can timing cause knocking?
On most modern cars, the timing of the engine — that is, at which point in the engine’s travel the spark plugs will fire — is controlled by the computer. But, if for any reason the spark isn’t firing exactly when it should, this can cause multiple detonations in the cylinder, leading to engine knock.
