Honda CRV knock sensor Sign In

So far I have most of the issues resolved for my used car.
The car's engine light is off but code reader is giving me knock sensor problem.
How important is the knock sensor for Honda CRV?

It wouldn't matter much if you only burned premium fuel in it.

Low octane fuel causes detonation (pinging). The knock sensor sees that and retards the timing to stop it. Letting it continue can cause severe engine damage and burn a hole right through the piston. Premium fuel would probably prevent that but would end up costing more than repairing the knock sensor.
