How to replace the Knock Sensor (KS) 1 on Cadillac CTS?

The first step in replacing Knock Sensor 1 involves disconnecting the Knock Sensor pigtail from the electrical connector and bracket before extracting the generator while maintaining careful note of the Knock Sensor pigtail path around the rear timing belt cover's retaining clips. First disconnect the Knock Sensor pigtail from its retaining clips on the rear timing belt cover then unscrew the central sensor bolt and finally remove the Knock Sensor from the valve cover. Starting the installation process requireswipe-cleaning all contact surfaces between Knock Sensor and engine block while making sure the sensor's contact area rests against the block directly. It is crucial not to use washers, spring washers, or toothed washers during installation; installation requires bolt tightening to 20 n.m (15 lb ft). Secure the Knock Sensor onto the engine block and position the Knock Sensor pigtail through the rear timing belt cover according to the original setup process while keeping it clear of all mobile components. Reinstall the generator then establish a connection between the Knock Sensor pigtail cable and electrical connector and bracket.
