So, I've looked and searched, and most places say that code P0330 is knock sensor 1, and code P0325 is knock sensor 2.
But then I found a PDF online of the manual (supposedly), and it says the opposite, that P0330 is knock sensor 2, and P0325 is knock sensor 1.

Looking for a definitive answer, or just more conflicting info, ˟˟˟˟ it I'll take anything

(this is for a 5vz-fe)

 

What MY version of the FSM for the 5VZ-FE engine, knock sensor #1 is 0325, and #2 is 0330.

Does that help in any way? I have been using this version of the FSM I found on this site since I got my 99 4Runner a few years back, and so far, everything it's told me has been 100% accurate. Including the codes it's shown me. And I've looked up a number of them. The codes in the 'book" match what my OBDII reader has said the code is, so I'll take it's "word" for it.

Something I found out when my #1 knock sensor failed, is that the computer only accepts OEM sensors and pig-tails. My mechanic thought he'd save me some money getting an aftermarket version, and immediately got a code. He went to the local dealership and got an OEM sensor from Toyota, and LO and Behold, no more code. Nothing at all wrong with the aftermarket sensor, it just wont accept it in the truck. Don't ask me why.

Hope all this is some help of some kind...

Thanks a bunch for the reply. Yeah that must be the same service manual I found online. I'd planning on going with that, it just seemed strange to me that I heard in mentioned pretty matter-a-factly on here and other forums that it was the opposite.

I am aware of how important it is to use OEM knock sensors, and I use OEM for just about everything when I can, but I had not heard anything about the wiring pigtail really needing to be OEM. I was only able to get an aftermarket one, but it looks identical (other than not being old and brittle and falling apart), and it doesn't really seem to me like just a little wiring harness could be that different? maybe I'm being an idiot about that though.

The reason it matters so much about which knock sensor is for which code, is because I'm out of the country and was only able to get one OEM knock sensor and the aftermarket wiring harness. I know it sounds like its mostly just a bad harness, but I'm going swap the knock sensor too since I've got it all taken part already. I just wanna make sure I'm swapping the one I'm getting the code for.

Thanks again for the info

 

My pleasure to be of some small help.

I don't think the pigtail would be as critical to be OEM as the sensor. AS LONG AS they did a decent soldering job. I've seen a lot of soldering jobs that are totally messed up. The famous "bigger the glob, the better the job" type. And usually it's a cold solder join.
If the solder job is decent, I would think the pigtail wouldn't be AS critical to be OEM as the sensor(s). Just my opinion, as a former radar tech with several military soldering schools under my belt.

I wish you good fortune!
