A knock sensor detects engine knock in the motor(aka pinging, detonation, or uncontrolled explosions. it basically means the motor is about to blow up or potentially could.) the second part to a knock sensor is that it keeps the ignition timing as advanced as possible to make the most power without making engine knock. So if you have a bad knock sensor or have a check engine light form a knock sensor your car will be slower. this is when your car goes into LIMP mode which is basically a preset running condition which is safe for the motor.
