2002 Yukon/Another knock sensor thread
I tested resistance back to both KS and they are both 108. Then I tested voltage on the ECU side. Both tested consistent 28 mv- pharpe

2002 Yukon/Another knock sensor thread
So I pulled it all back apart and replaced both knock sensors and all the wiring with the ACDelco stuff. JCleard codes then did a drive and both P0327 and P0332 are back Pending Faults. No Idea what to do now.- pharpe

2002 Yukon/Another knock sensor thread

2002 Yukon/Another knock sensor thread
I've been reading knock sensor posts and watching videos for 3 days and I'm really in need of some direction. I have a 2002 Yukon with a 5.3. It was throwing a knock sensor code. It was only one but I don't remember which. I watched some videos and ordered two new sensors and a new harness...- pharpe
