I need a diagram to help me locate the EGR valve and throttle body for a
2001 Camry (4 cyl.).

I can fix computers, but this 'geek' does not know squat about cars.

Since I just need to view it briefly, then send it to my printer I very much
prefer a "free" diagram source. I have found plenty of sites that want a
fee.

Any ideas?

Just curious, why do you need to locate the EGR valve and throttle body?

The EGR valve is easier to find with a diagram, there are 2 very easy ways
to find the throttle body. Open the hood and look at the engine while
someone depresses the throttle pedal. You will see a cable attached to a
bell crank, that looks like a pulley rotating. The bell crank is attached
to the throttle body, which is a tubular metal with some wires and the bell
crank sticking out. If you do not have a helper, open the hood and look at
the front of the engine compartment on the driver's side (U.S. driver's
side). The air filter housing is a black plastic box with clamps that sits
behind the headlight. There will be a black plastic tube coming out of the
air filter housing that connects to the throttle body with the bell crank I
described above.

You're welcome! Why are you looking for the throttle body and EGR valve?

My Camry is stalling at traffic lights after about 10 minutes of driving
(possibly once the EGR valve opens because of the higher temperature.)

I found someone (actually several people) in a Toyota forum with very
similar problems. Most found they're stalling problems (after a short drive)
were due to a faulty or clogged EGR valve.

One poster suggested disconnecting the vacuum hose, then take a test drive
to see if the stalling goes away. If it does there apparently is an even
greater chance (than just symptoms alone) that the EGR valve needs replaced.
So this is why I needed to find out where it was located.

Hope this verbose reply answers your question.

Michael

Yup, that happens to be the advice I give to people for cars that stall when
idling. When you disconnect the vacuum hose from the EGR valve, be sure to
plug the disconnected hose or you will have a vacuum leak. Golf tees work
well for this purpose, as do sheet metal screws.

Be aware that you may get a check engine light when you disconnect the
vacuum hose from the EGR valve. You can clear the light with an OBD II scan
tool that you can borrow for free from many auto parts stores (Autozone has
a free loaner program for scan tools) or you can clear the light by pulling
the EFI main fuse.

Thanks for the tip.

I just wanted to update the status of my EGR valve issue. The shop just
called and said they found a little piece of carbon in the EGR valve. Great
news!

That is good news. You can slow down the buildup of deposits in the EGR and
on O2 sensors by taking the car on the highway and let everything get good
and hot.
