EGR Options

[Sinyk]

Can anyone tell me, is there a difference between EGR valves over the years for the 5S-FE?

Is an EGR an EGR an EGR?

[Smaay]

for the most part yes. as long as the hard lines all fit. you should be good to go

[Sinyk]

I had to get a new one yesterday as mine has stopped holding vacuum. The local dealer wanted $380 + tax but 1sttoyotaparts.com had them for only $165

[Smaay]

love those online parts places.

love those online parts places.

New EGR arrived yesterday, took only 3 business days to arrive! (Probably the fastest thing I've ever had coming across the border)


The culprit who was throwing codes:



The replacement:



Old, leaky and dirty:



Shiny and new!:



Cleanest thing in the engine bay:



I won't say it's the best $200 spent, but it feels good to know the problem was solved for about $350 less than my mechanic wanted for the job.

Now if only an EGR added HP... Oh well, lower emissions ftw!

Aye, 1sttoyotaparts.com has long been a great source -- actually, it was recently taken over by another Washington state Toyota dealer, and one of their techs is a longtime Celicatech.com member, which is how we learned it had moved.

6 days after replacing my EGR, I get a check engine light again, same EGR insufficient flow code as before. My mechanic originally told me my egr valve wasn't holding vacuum and said it had to be replaced, so it was replaced, so what else could be the problem? The EGR modulator perhaps? I took a look at the vacuum lines and most of them seem to be in good shape and fit tight. Most of them run together under the engine to parts unknown to me (VSV? Does a 5sfe even have one?). I'm running out of culprits and I want to get this problem solved. Anyone have any ideas?

[Galcobar]

Tubing could be clogged, even if it's in good shape.

[presure2]

yea, it could be the tube, or VSV or modulator. i would hit a junkyard for some spare parts.

I have plans to replace the modulator and the hose from the modulator to the EGR. Are you referring to the metal tube from the manifold to the egr? I have cleaned that thing many times over, but i guess replacing it couldn't hurt.

Also, where is the VSV? Sadly, all I have for reference is a Haynes manual :\ I looked at the diagrams and tried to locate the VSV where they showed it to no avail. Can anyone help me find it? Picture or a really good description?

[Smaay]

the VSV is the funny looking thing with 2 vacume lines on it. its mounted on the head right between the runners of the intake manifold. ill try to find a pic for you



this might help too

[Sinyk]

So the VSV is on the intake side... Hmmm.. I was looking on the exhaust side, that might be why I couldn't find it. Still, back there is not an easy place to investigate. Perhaps it would be easy to spot from under the car?

I can't seem to find a part # on 1sttoyotaparts.com for the VSV. Help?

Hello did you ever get this figured out? I am getting the same code for egr. Just wondering what to attack? Thanks

[delusionz]

That EGR stuff doesn't exist on Jap spec but what does that TVV for EVAP and Charcoal Cannister do? I think I've seen something similar to that.

x2, my dad's 5sfe camry is also giving the same code, would be great to know what the problem really is, instead of buying it all.

[Smaay]

im actually getting both codes, insufficent and excessive flow. very fustrating. i just dont have time to investigate it. im going to pull the engine soon to paint the car to ill dig into it then

[presure2]

the easy fix is just to unplug the sensor, and bridge the 2 pins on the harness side of the plug.
no more code.

That is so cheating, but cheap! LOL.

But since the car is thinking that something is wrong here, is the "thing that is wrong" hampering performance in anyway? Decrease in mpg, etc?

Like on the camry, the car runs fine, no weird idle, nothing, just the annoying light that comes and goes.

[bdog_v]

X2 I am trying to get the maximum fuel mileage so if disconnecting it would lower the mileage I would not do it. However on many other cars especially old v8 muscle we disconnect the egr and don't notice anything changing however on these new computerized yotas I am not sure if it would affect mileage. Has anyone tested for this??? It would be nice to get rid of that code and not spend ridiculous amounts of money to fix it.......
Thanks

[Sinyk]

I guess I never followed up on this post. I ended up replacing the modulator as well about 5 months ago and I have been code free since. I'm starting to suspect that the modulator was at fault all along. Oh well!

[RavenAegis45]

So the EGR valve takes gases directely from the Exhaust manifold? I Always thought it got it further down, interesting

[94STJR]

i have a 94 st with the 1.8 and my check engine light is on because of a EGR failure. i've replaced the EGR valve but that didn't help my situation any. do you all have any idea of what to replace/check next?? Thanks

[dabazied]

Have you replaced the modulator? Have you reset the codes yet to see if it comes back?

[96stgreendemon]

same problem, my cel came on got it checked and they said it was the egr system, whats the cheapest route and how hard is it to fix this myself

[Sinyk]

Of the two major parts related to the EGR system (modulator and valve) the modulator is by far the cheaper one to replace. I would replace it and also remove the valve, give it a good cleaning with a pipe cleaner and some carb cleaner.

[96stgreendemon]

hopefully the modulator will work, i ordered it yesterday and hopefully it will be here soon, but if that wont solve it i will take off the valve and clean it out, but that damn valve is epensive!!

[96stgreendemon]

ok this is odd. ok order the modulator and the car must fkn know!!! cel has ben on the past 2 days, pull into a gas station today and fill up, get back in the car and the cel is off, wtf??!!! i mean im not mad about it ha ha but u think the egr just messed up for a few days cause of the cold?

[Sinyk]

When my EGR threw a CEL, it never went off, so I don't know what's up.

[celicaboston1983]

got the same problem changed the egr valve and a whole bunch of other things I just gave up its been like 3 or 4 yrs and the car still runs fine

[samir0189]

My CEL had been on and off for the last few weeks, code 71, egr. The odd part was, for the beginning of the time that the light would come on, it would literally flash at me, stayed on for 3 seconds and went off, as time progressed i noticed that the light only came on when my gas tank was full and between 3/4 tank, then there would be no light activity thereafter, until the next fill up.

Weird coincidence? or does the gas tank level have something to do with that?

Anyway, now, more recently, the light has been on constantly, every now and then it will turn off itself, but it soon comes back.

I dont have the money to go guessing at the EGR system, and since it isnt bothering anything as of now, im not gonna fix it. BUT i am curious how the gas tank levels affect this!


Also, i thought (from what i have read) the CEL system was designed to check only every x miles on the performance of the car?? Why would it think it has a problem and then in 3 seconds to a few minutes decide everything is ok??

interesting progress of this thread...

I still have a 401 fault for egr flow insufficient...and I've already replaced the valve and modulator and the VSV was replaced just before I got the car(from a coworker)...

another mentioned the charcoal canister could be the cause, as it turned out to be the problem for his egr on his Firebird.
