what is this?

[01thunder]

what is this throttle part called? the connector which you see disconnected is broken and i need to replace it. anyone know what the part number would be for the connector or where i can find it?

 

[gs300tt]

That looks like a drive by wire throttle body and they most likely call that a pedal position sensor. I know the sensor cannot be purchased by itself from Toyota, but I do not know about the plug. Your best bet is to find a salvage yard and see if you can cut one off a harness.

yeah, could be a spendy fix from the dealer. is it not something a good 'ol zip-tie could fix?

That's the connector for the throttle position sensor (TPS). If the connections are good, I'd use a zip tie (like above) or put some RTV sealer on it (not the contacts) and slide it on. It'll seal well and stay put (and be hard to remove the sealer if you ever have to).

Here is a picture of a drive by wire throttle body the TPS sensor is on the left. I believe it is only three wires like most TPS sensors. The connector in question is on the right and is not the TPS sensor.

no yards around here to find these in. and if there was, they would probably be as brittle. it's not the tps, as that is on the back side. it's a motor but for what? if i knew, perhaps i can find the connector.

The service manual calls it the 'accelerator pedal position sensor'.

that's it ozarks thanks. got it ordered!

It's actually a VTPS.....the earlier TPS was more of an on/off switch, basically notifying the ECU of 'off idle' open-closed loop (fuel map)......later throttle bodies utilise a variable sensor, returning a far more accurate indication of throttle position.

It is not a VTPS or a TPS it is an accelerator pedal position sensor as stated above. The amount of disinformation that gets put up is astonishing. The sensor reads the position of the pedal through a cable instead of being mounted on the pedal assembly like more modern drive by wire systems. With the power off if you complete depress the pedal or pull the cable the throttle plate will only open a little this was done in case of failure you will be able to limp the truck around. If you turn the key to the on position a motor will drive open the throttle plate relative to the position of the accelerator pedal position.

Just so I'm clear on this, you're saying The Gen 3's are a fly-by-wire system - driven in turn by a cable attached to the accelerator pedal?

 

[Robb235]

I'm pretty sure the later 3rd gens were fly-by-wire. I want to say '01 and '02? I know my '99 is not FBW.

Ones like the one in the picture above are. I know 01 and 02 are the 2000s I am not so sure on. If it has only one cable attached to the throttle body it is a drive by wire version.

In that I case I stand corrected Sir....opologies for any misleading information :wacko:

I have to wonder why the hell Toyota went to all the trouble of adopting a fly-by-wire system & then run a throttle cable when they could have simply fitted a sensor to the pedal & ran a current from there.....seems like a half-arsed attempt to me, it's neither one thing nor the other!
