Default Looking for a vac. modulator

After looking for clues as to why my 93 Camry gives not-so-good gas mileage,
my mechanic recently found that the EGR Vaccum Modulator (not sure of the
right part's name) was not fonctionning at all.
Any opinions out there?
Anyone knows where I could find a used one for a 93 Camry 4cyl. by any
chance?
A new one is 110.00 CAN$. Ouch!
Thanks guys.

JP

Try ebay.

Or buy a new one for USD $43.99 from Toyota dealer:

Already did.

After exchange rate and shipping, it would be almost as bas as buying in
Canada.
But thanks for the suggestion. I'll email the Toyota dealer to see what they
would charge for shipping.
Appreciate.

Why are you so sure the EGR Modulator (aka: transducer valve) is
faulty? It operates on the principle that air pressure must be
present in the tube connected to the exhaust passageway in order for
the valve to NOT vent all vacuum attempting to reach the EGR valve.

All I can say Philip is that my mechanic had a test tool in his hands when
he checked
the valve and when he pressed on it, the meter would go to 0 pressure.
I don't know if I explain well but, if it's not clear, I'll ask him to
explain his procedure
and will relay it to you.

MUADIB ... go hose yourself with a seltzer bottle. Use the whole
thing on your face. ;-)

That anyone's mechanic "says so" is reason enough for me to inquire
further ... if nothing else but for MY curiosity. If that is okay or
not with you is of no consequence. >:^)

You can test it without a tool and off the car.
For detailed description see picture on page 3 of document
http://www.autoshop101.com/forms/h61.pdf

1) Block port Q and blow air into either ports P or R (block either and use
other),it should leak through filter (Normal)
2) with help of a 2nd person, blow into Chamber A and keep pressure on, at
same time redo step 1. There should be no leakage, AIR should flow between P
& Q ports.

Or test EGR Modulator on the car per above document.

IceMan: Just one caveat: LIMIT the air pressure applied to "Chamber
A" to no more than 4 pounds. If you accidently use a lot more than
that, you will burst the diaphram ... in which case you ruined a
perfectly good valve. Buy a new one.
