3VZE Throttle Body's
 

Hey guys this might be a stupid question but I'm just wondering about the 3vze throttle body's. did they change threw the years or did they remain the same? Example being I have a 94 3VZE motor with a bad throttle body, could I use a 89-93 throttle body? Just wanna make sure before I buy the wrong part. The stealership wants 500$ for a new throttle body

Only differences I know of were between auto trans and manual trans. The connecter for the TPS also changed but that doesnt mean you couldnt keep your original TPS just swap it out on the new throttle body.

Ah that sounds interesting, could anybody else give another conformation?

Whats the diff auto/manie?

The auto's have the kick down cable mechanism. Which wouldnt be a problem if swaping a auto TB to a manual truck. But the other way around would be a problem.

And this one im not sure about, but theres a vacuum plunger thingy on the auto that I had. It pushes open the throttle to idle up the motor. It could be for Air conditioner, or the auto trans to control idle when in gear and not. Or both. Vehicle im referring to was a 95 4runner 3VZ auto.

Id say if theres no obvious differences then give it a shot. Worst case it doesnt work and will leave you always wondering why until you get to the bottom of it.

I have one off a 95 Ill sell you...

Ya that thingy in the square is what Im talking aboot.


I see cable pulleys for cruise control, throttle, and the trans cable on that TB.

that would be the throttle position sensor (tps)

I think most things on the 3VZE engines are interchangeable between the years 90-95, I have a 91 pickup with the 3VZE and have been able to interchange between those years no problem.

No. The TPS doesnt have a vacuum line coming out of it, they use a thing called "electricity which uses "wires". Not vacuum lines. :)

But in case you ever need to now were the TPS really is:

You were close though. :great:

In most cases. And dont forget about 88-95. But the TB from the picture is different than the ones found on manual trans trucks. Which is what the post is about. And this would cause a big problem if one was trying to put a TB from a manual on an auto truck. That and the trans cable pulley being,,, well I dont know missing...

Not Interchangeable
 

The throttle body's changed over the years for 89-93 Pickups and 4Runners. I have a manual 91 Pickup (3VZ-E) and I do not have the hoses and parts circled in red below:

They are NOT interchangeable. There's a distinct difference between manual and automatic, those with cruise control, etc. They added more vacuum lines over the years as well.

Again the Intake pictured is from an auto trans. There is no reseon it couldnt be used on a manual truck. It has extra parts, not lack of parts.

I installed one of these on my 89 manual pick up for the cruise control linkage. It works well with a few small issues.

Toyota changed the TPS to point downward. Also the connector housing changed so the newer TPS will not plug into the older wire harness.

I got around the problem by using the older TPS. Also the TPS actuating arm on the end of the older TB needs to be used.

Changing the TPS to point sideways causes the 'fast idle start up' arm to hang up on the TPS connector at WOT. I bent over the arm alittle for clearance. Then bent the vacuum plunger over to realign to the arm.

hey guys whats the two cables on the left side of the trottle body i just changed my engine and i didnt have those cabbles on my old one and i was wandering what they where for and if i needed to get some

The throttle body has the throttle cable, the automatic transmission throttle cable, and the cruise control throttle cable. All on the forward side. If you have a manual trans and no cruise, you only need one cable.

Note that btu44 has after-market cables.

Hello,

I need to replace the Throttle Body on my 3VZE 1989 Manual Transmission PU 4X4 Ext. Cab.

I was wondering if I could use a Throttle Body from a 5VZE since the 3VZE TB is very hard to find. (One in good condition). OR any other options available.

Seems unlikely to me that you really need to replace your throttle body, but who am I to tell you what to do?

(and no, it won't fit a 5VZE)

Hi. I found this thread when searching for help with 3vze throttle body. My TPS sensor was facing toward the PASSENGER side of my truck. This was practically impossible for me to get in there and see what was going on, remove the connector. I think this is how the factory sells it. I see that you have yours facing the driver's side. Face the driver side make it much easier to take that off and get in there with the probes, and see the terminals. Thank you for posting the pictures.
