Will an engine run without a knock sensor?

Can I bypass knock sensor?
Your knock sensor is an electrical device on your truck, car or Sport Utility vehicle that detects knocks in your engine caused by premature detonation of the air-fuel mixture as it enters the cylinder head. If you ever need to bypass your knock sensors, the most direct way of doing so is to simply disconnect them.
What causes knock sensor problems?
Another cause of the car being slow to accelerate besides the knock sensor is a leaking fuel line, dirty airflow sensor, a vacuum leak, or a failing catalytic converter, that can prevent the proper amount of air from going to the engine and powering the car.
Why would I get a knock sensor code?
