EGR setting off code

by **99V6solaraSE** » Tue Mar 25, 2008 8:22 am

I think i know know why im getting the insufficient flow code. I guess when they fitted it on, they obviously had to bend it it slightly so its probably constricting the flow a little.

should i be concerned? I mean if its nothing serious then i can live with the CEL on.

well Dont know but I have like 6 months or so running with 2 EGR codes on Insufficiet air flow and to much air flow both are on dont know why

you're egr valve might be malfunctioning.

that maybe be it

Awesome. Fix that and let us know what happens. now i kow to get my pipe extended a bit. There is hope for the peeps who are TRD EGRless.

if it doesnt really affect performance im not gonna even worry about it.

From my understanding, the EGR is only there to heat up the cats for emissions purposes. If you dont have emissions, then it isnt going to hurt anything... Im currently running with my EGR blocked off and a code for insufficient flow. i have heard you can wire a resistor in somewhere and the code will be eliminated, but I am not sure where this is yet.

Let us know what you find out. I'll run a block off plate if I can trick the ECU to not throw a code. BTW I will have to let you know about the begining of summer about the install if you are still up for it. If you offer still stands, so does mine. give me a call.

^ for sure, Once things calm down and Im done with exams I might be able to swing it.

All I know is my friend with an SC300 told me he wired a resistor on his car to trick the ecu into thinking the EGR system is working, so once I am home for the summer I might see if he can help me do the same on my solara... I have no idea where I would need to wire it yet though.

here is a link he just sent me- should be a similar process on our cars, Ill have to see what i can figure out.

From what i gather, the EGR gas temperature probe electrical connector is the place where we need the resistor on our cars, the same as the one illustrated.

I am trying to find out what size resistor we would need to cancel the code. My Haynes manual lists the following temp readings and resistance measurements in respect to the EGR gas temp sensor:

122 degrees: 64-97 k-ohms
212 degrees: 11-16 k-ohms
302 degrees: 2-4 k-ohms

Im no electrical engineer, so Im not positive what that means :lol:

Where is Midias when I need him? :lol:

EDIT:
It sounds like if you use a resistor for the medium range, it will cancel the code. He said a resistor anywhere between 11 and 16k ohms should do the trick. I dont have my car at home right now, but Ill be going to radio shack to pick up some resistors and try this out as soon as I have my car! Hope that helps you guys and I hope it works...

Are all you people w/o the egr pipe just running block-off plates on the egr cooler and s/c?

by **YESCA** » Tue Mar 25, 2008 3:09 pm

^^^most are yes. Some people like myself cannot run anything due to emission standards in our states. I'm not sure how it is any other place, but in Missouri if you car is 97 or newer and you have a CEL light on, no matter what code it is throwing, you fail no questions asked. Then they give you 30 days to get it fixed, and if you don't you have to pay $400 for a waiver that will let you drive with your CEL light on. It's complete BS if you ask me.

^^just pull the gauge cluster and remove the bulb behind the service engine soon light...its worth a try anyways for $400!

by **akora12** » Tue Mar 25, 2008 3:34 pm

Man, emission laws blow. I've never dealt with that, so I guess Indiana is good for something. I like the idea of temporarily removing the CEL light in the gauge cluster, though.

That won't work.... they plug the computer in the testing port to see if there are any codes. I have thought about that...LMAO!
