Knock sensors on an LS
 

I had a scan done on my 05 Silverado after the check engine light came on, it came up as a bad knock sensor...#2 I think. Poking around the Internet it looks like it's one of two under the intake. Besides two new sensors, sealing the plugs with silicone and new manifold gaskets is there anything else I should be doing? Do I need any special tools?

Thanks in advance.
:thumbsup:

intake gaskets, knock sensors, most likely the knock sensor harness. then build a dam around the sensors to keep em dry and then ur good. basic tools, and a fuel line quick disconnect tool

Got it, I'll need to borrow a fuel line tool from someone in the hood it sounds like. So maybe a dumb question but, looking at RockAuto it appears all knock sensors are the same...do I just order a few Delphi sensors and call it a day?

I saw that, didn't watch the entire thing due to motion sickness! If you're going to take the time to make a video why not make a decent one? Some peoples kids....

I'll get the sensors ordered and see how it goes.

Thanks

I know, what a Richard right?:lol:

Vince, are all sensors created equal? Delphi good enough?

Greg, thank you for the video, the parts and the secret Santa gift. I appreciate you....

:hello:

for the most part the are. delphi will do. the killer of em is water and/or oil getting to em.

Buy one of these http://www.lingenfelter.com/mm5/merc...2#.VhEyi5cWYq4 and a flat valley cover ( can be found on e bay ... etc under knock sensor delete) and move them to the side of the block.

Don't the Gen IV sensors work differently than Gen III?
