I did a motor rebuild, and I don't know what this is, and I can't remember if this plug is supposed to be hooked up to anything....

Thanks guys

is it putting on a check engine light

3VZE? I'm thinking oil pressure sensor.

Team420

oil pressure sender? or knock sensor? I'm guessing its a 22re....

fitzman62

i think it is the knock sensor

Erik Beeman

It's a 92 22RE, and no, no lights come on.

I do have a engine sputter and it KNOW it's something to do with the ECU cause it happens only under certain circumstances. I think this sensor might have something to do with it.

I have Chiltons sitting in front of me, but these F'n things are useless.

Yep its the knock sensor on a 22re and it needs to be plugged in.

Erik Beeman

What's the effect of it? No lights came on and it's had almost 400 miles put on it. Maybe this will fix my problem.

Team420

it retards the timing when it senses engine knock or octane ping...etc. It wont throw a code or cause any problems till 1700rpm, and should b plugged in if you dont wanna burn lots of gas, and have even less power.

Erik Beeman

Dude, this could totally save me. Sputter is around 1800, under easy throttle movement. Seemed low on power too for being fresh rebuilt. I am putting the truck on the lift as we speak, hopefully I can figure this out.

So in the factory Toyota manual it says Knock sensor is 4WD only, so I guess I don't use this sensor.

Yea ya do I just plugged mine in a few min's ago you should have a single pin wire that comes down the side of the wiring harness it should be gray that's the plug that go's in there.

Yeah you should plug it in. It will mess with your fuel mixture and make your truck run like crap. Mine was faulty and one day it wouldn't start. Don't want that happening to you now do you?

Erik Beeman

I have a two wheel drive....Toyota says it's only used on 4 wheel drive....

Erik Beeman

I can't find a plug.

iamsuperbleeder

I think if Toyota put the sensor on the motor, there's going to be a wire there, or at least there use to be one, lol

have you priced a new knock sensor? yeah, that's be stupid to put something priced like that on there if it's not going to be used, lol


everyone's right, 22re, knock sensor; really need to peel your wiring harness apart and find that wire and plug it in

Erik Beeman

Yes, you're right. It was on the block when I bought the truck. I don't remember if I un-plugged somthing there, or not. Lol.


Oh, wait........I have another 2WD 22RE in my driveway, I could just check that. DOH..!

Erik Beeman

Ok. So my 88 has this sensor, and it has a plug. But, I CAN NOT find anything on this 92. There are no wires or any plugs that are even near it.

I jjust searched for an hour

on my truck the wire on that sensor is just dangling. i was told that it was for the oil pressure guage.... i don't have a op guage in my cluster so i never bothered messing with it.... but now that you guys are saying it's a knock sensor i need to know where the other end goes

does anyone have a picture? or detailed info on where the wire goes from that sensor?

i've had a random sputtering/bucking problem for awhile now

I do believe one o them thar dealeos is the oil pressure sender, an ta other one be water temptre
