• Q: How to replace Knock Sensor 1 on 2007 Cadillac XLR?

  A: To replace Knock Sensor 1, remove the supercharger assembly first. Disconnect the electric connection from the knock sensor (KS) and unscrew the center bolt of the KS. Remove the KS off the engine block. Subsequently, clean the mating surfaces of the KS and the engine block of any contamination until your entire contact surface of the KS rests directly on the engine block. That is important not to use washers, springwashers or toothed washers installation; This can be achieved by hand, but an impact wrench would provide an additional margin of safety. Once tightening is complete, it is important to make sure the installation is correct because an incorrect installation will result in the engine using more fuel than necessary. Mount the KS and the bolt to the engine block, while turning the KS bolt to 20 N.m (15 lb ft). Make sure that the KS wiring harness is properly installed, connect the electrical connector to the KS before reassembling the supercharger assembly.
