P0325 will NOT go away (knock sensor) - Page 4 - Toyota 4Runner Forum

In 30+ years of wrenching I keep seeing the quality of replacement parts, even OEM replacement, continue to slide. I went through three Delco crank sensors on a Chevrolet Silverado before finding a good one last year.

Hats off to you for getting it fixed.

Congrats! Also bear in mind (future searchers) that continuity needs to test out both positive and negative. If you pinch a wire you might still have continuity, but if you break the insulation and now have continuity between the grounded shielding wires and signal conducting wire (where there shouldn't be any), it's likely to be just as bad as having no continuity on your signal wire. So also check continuity between signal wire and ground to make sure it doesn't exist.

Hey, guys... I'm in desperate need of some help over here. I have a 2003 V8 and I got the P0325 code the other day and need to get it fixed ASAP. I'm going to get both done, I just can't find OEM sensors online anywhere. They have been out of stock or the sellers look way too sketchy and cheap to be authentic. Can somebody please help me out and throw up a link to the Denso knock sensors and wiring harness? Any help is much appreciated!

Oh, and I'd get them from my local dealer but they want $250... each.

Are you positive the KS are the same for the 4th gen V8 as they are for the 3rd gen V6?
If not the part numbers are;
89615-12090 Denso Knock Sensor
82219-34010 Toyota Knock Sensor Harness

Of course you will need all the necessary gaskets too, whatever they may be. Just so you know, the Denso's don't get much cheaper than $160-180.
You COULD try Amazon, which has them for $100, but what raises my eyebrow about Amazon and listings like this is it says it's genuine, and it's being sold directly by Toyota, yet lists it at less than half of what Toyota puts it for on their own website. Idk, just seems funky to me.

I was sure until I checked a second time. They aren't. Thanks for bringing that up.

The only choices I have from Rock Auto are these --

And the only ones I find on ebay are listed for $14.
OEM# 8961522050, 8961552010 New OEM Replacement Knock (Detonation) Sensor | eBay

They say OEM but for $14 doesn't seem legit. All I've read says to make sure and use OEM parts for this job but I'm not able to find any that look legitimate.

Have you tried partsouq? Got my harness from them for pretty cheap, and was OEM. I was a little wary of them but they seem g2g, and I cant find any negative reviews on them
From what I understand some people like Toyota have bases of operation over in the UAE, and retailers like partsouq are local to them and able to do business directly
