So I was out driving today, finally got the car back together after the PCV system done and the EGR cleaned out. I was enjoying not seeing the service engine light. Key word is WAS. Light came back on again today and is coming back as a code for the knock sensor. Now, i KNOW I moved it when i was doing the PCV system, because it was in the way of taking off the bracket that holds the intake manifold from the bottom. I dont remember 100% if i got that bolt back tight or not, but I'm guessing that it didnt go bad, it just isnt tight. Can I get at this little booger without removing the intake manifold again?

Oh, does the knock sensor have to be installed in any particular orientation? because i KNOW i didnt put it back to where it was.

 

Yes 3 o'clock position for the front sensor, 5 o'clock for the rear sensor.

 

What a giant pain in the ***. Guess i gotta take the car apart again. Yay.

 

Yeah, sounds like you do. I guess this will help you learn for next time.

 

Yeah Im doing the "While Im in there" list of things. Im replacing the PCV system while Im doing the knock sensors this weekend. This is reverse of your original situation.
