Error code: P0325 WHERE TO BEGIN?

I've got a 2003 Tundra 4.7 v-8 and I'm getting an error code P0325. Where to begin? NO IDEA!! I recovered a stanky dead rat from under my cowl and I'm pretty sure that dirty bastard chewed up the wire harness for the "knock sensor". Won't know for sure until I get in there.

I looked at a wire harness, it's only about $45.00. I know that one end of the harness connects to the seNSOR but WHERE DOES THE OTHER END OF THE HARNESS GO?

It was suggested that I get new gaskets since I'll already have the manifold off. IDK but that sounds like a good idea to me.

Do y'all have any step by step instructions for this sort of thing?

Any help is appreciated.

I added this info to the linked thread. The page that thread references is dead and it doesn't look like anyone pulled a PDF of it. But Wayback Machine at least has a copy of the text info here: https://web.archive.org/web/2019021...-tundra-starter-repair-a-journey-of-discovery

 

attached pdf of same article with images !

 

Thanks for info. I will check out everything y’all sent. Very thankful gents.

 

That's one of the first things I did to my truck. Rodents chewed up my knock sensor harness in the valley. I couldn't ever find the other end of where they go; I beleive they're hardwired back to a main harness.

I went to toyota and bought a new KS harness, but I'm pretty sure it was an 05-06 harness. I ended up just splicing it in and taping it up in the valley. Of course I didn't get picks of that though...

 

Bastards!
