What is knock sensor on Honda s2000?
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.
