Masterparts stocks a complete range of knock sensors.
The knocksensor creates a voltage signal based on the vibrations caused by detonation. The computer uses this signal to retard timing when spark knock occurs.
It can typically be located in the lower engine block, cylinder head or intake manifold.
Knock sensors are designed to respond to knock frequencies up to 1000 Hz accommodating shifts in engine knock frequency, making it a more flexible sensor responding to correct engine knock over a broad range of vehicle conditions.
