Location of TPS (Throttle Position Sensor)

I've got a 98 4Runner V6 that's throwing a check engine light for bad Throttle Position Sensor (TPS). Does anyone have a picture of where this is located? I'm going to swap it out for a new one, but have no idea where to look. If you have instructions on swapping this unit that would be great as well, or a scan of the page from a manual.

Thanks in advance,

The throttle cable attaches to a spool on the throttle body. The TPS is on the opposite side of the throttle body from this spool, next to a vacuum diaphram. The TPS has a three-pin connector.

Great description, I found it right off.

It looks like it just needs to be unplugged and two screws removed to swap it out. Is that accurate or am I missing something?

Just seems too easy, so I'm paranoid.

It's that easy. Just don't strip the screw heads. Maybe put a drop of penetrating oil on the screws first.

Thanks a million.

Alot of times when replacing the TPS there is a way to set it up for better milage/performance to stock specs by watching for voltage value or ohm value on certain wires by moving it back and forth with screws loose and throttle shut in normal closed position...check with service dept. at a local Toyota dealer to be sure on your application..no offense to others kind enough to give what might be dead on correct advise,just never hurts to ask questions of those that make a living working on them if in doubt :o)

Happy holidays
