To remove the knock sensor, the intake manifold plenum must be removed (refer to Section 3 for these procedures). When all components are removed, simply unscrew the knock sensor with an open or box wrench. Make sure not to damage the sensor.
To install the sensor, tighten the sensor into the engine until snug. Make sure not to crossthread the sensor into the engine. Install all of the components taken off of the engine for the sensor's removal.
