Default Re: '98 Camry EGR Diagnosis

1998 Camry, 4-Cyl, 70K miles. Check Engine Light comes on. OBD II
Scanner says "Insufficient EGR Flow." I cleaned and blew-out the EGR Vacuum
modulator and reset the ECM code. Eventually the Check Engine Light comes
back on. Is there an easy way to check to see if I should just replace the
EGR or if the problem is something that controls the EGR valve?

Pull vacuum on the EGR valve while the engine is running. Autozone has
free MityVac rentals where you pay a deposit and get full refund when
you return the tool.

Your engine should run rough or stall and the EGR valve should hold
vacuum. You should also check to see the throttle vacuum ports leading
to the modulator aren't plugged.

If these checked out and you still have problems, let me know. Or do a
search on EGR VSV and modulator tests. If there isn't carbon plugging
up the EGR pintle valve, then there is little that will go wrong with
any decent EGR system.

Good to hear you found the VSV as the culprit and replaced it. Can you
tell us about the company that sells the discount VSV? For our future
reference. Thanks.

hello,
ok I'm having the same problem. I replaced the EGR but after about 2
days the check engine ight came back on. Where is the egr vacuum
solenoid valve located? And where can you buy one. I've been searching
on line with no success. I have a 2001 Camry with a 4 cyl.

The VSV is located between the #2 #3 intake plenums. Just above the top
of the rear engine mount.

With the engine off, disconnect the vacuum hose from the EGR valve,
blow air through it, and you will hear the air coming out of the VSV
air filter. It will help you locate it. The hose is dirty BTW.

Default Re: '98 Camry EGR Diagnosis

Sorry I haven't been checking out the newsgroup since last week.

The EGR VSV on my 97 Camry was located on the passenger side way down behind
the intake manifold kind of behind the motor mount. I don't know if this is
the same location on your or not. I you follow the vacuum hose going to the
side of the EGR manifold that has only one port that one should go to the
Vacuum Solenoid Valve.

I found a supplier http://www.toyotaautoparts.com/ and got it a lot cheaper
than my local dealer.

Hope this helps.
