Hello, i just bought a 2006 1500 with 17,000 miles and its giving me some engine troubles once in a while it will ideal ruff. well i changed sparkplugs didnt fix it. hooked it up to the computer and it said engine missfireing on 2,5,7 randomly. so i changed mass airflows. i also changed the coil packs on 2,5,7 seemed to come out of the ruff idealing. well the engine light stayed on! hooked the computer up and got theses codes. P0327, p0332.
any help would be apperciated

 

anyone?

 

P0327 is knock sensor they both are knock sensors I think. Try to Google just the codes thats what I did.

 

ya i figured that one out but how to fix it is my main question

 

you'll have to change the knock sensors and most likely the pigtails...but thats not making it run rough....it'll just default the timing

 

The knock sensors sit in two depressions in the valley cover. They tend to collect water if any gets in there and will quickly ruin the sensors. Like Argon said, you'll need to replace both sensors and the harness.

Stupid design....I think they went back to the old style on the newer vehicles and put them on the side of the block.

 

To fix it you have to disconnect all of the vacuum, fuel lines, and so on, and lift the intake manifold off. You need a specialty tool for the fuel lines, although it CAN be done without disconnecting them, it's just a little more time consuming and frustrating. You'll see the knock sensors sitting under the two useless rubber plugs. When reinstalling, some guys silicone the permieter of the plugs to prevent this from happening again.

Argon has probably changed 1 or 70 of these so he likely knows the quickest way to do it.
