  A: Start the Knock Sensor (KS) 1 replacement by disconnecting it from the wiring harness then removing the generator and drive belt fastener. Carefully keep track of the positioning of retaining clips around the Knock Sensor pigtail because it needs to pass through the back timing belt cover.

Reinstall the Knock Sensor pigtail according to previous removal instructions while maintaining its separation from all engine movement and secure it back into the holding clips.
