New 4.7 (2008 truck) SINGLE knock sensor?!
Hi all,
This is for a 2008 (3rd Gen) with the newer 4.7 like the 2009-2013's have. I hope its ok to post this in the 4th Gen forum for that reason.
My little brothers 4.7 overheated and got a few stuck lifters a while back and we bought him a crate engine and installed it at home. All went well but the new engine just didn't have the same power. We found a knock sensor code for sensor #1 only. So I pull the intake manifold tonight to replace the sensors only to realize its not bolted to the block.
It was laying on top of the transmission. Yes, I'm a quite ashamed to admit it. I guess one missed thing isn't too bad for doing it in the yard.
I'm ready to put this back together and see how it runs but there is only one sensor. I traced it back to the plug and there's only one wire. Everything I can find says it should be two? Everything except for a few parts stores shows two. And if I just go with the one, which side of the block does it go on? I don't remember where it was on the old engine. Maybe because its an 08 and its the first year of the new 4.7? I'm hoping someone here knows something I'm missing.
Thank you in advance!
