Re: EGR
Quote:
I found a garage with only a 2 wheel dyno so they would have to do the idle test only, I reset the ECU in the parking lot of test garage, and they ran the car. I passed. So, my conclusion is that this part is meant to just waste space under my hood and make light on my dash come on. I just want the whole damn thing removed I think. My CEL is still on for EGR.. My emissions was due in march. Just got my letter saying I cannot renew without passing emissions.. I should go do that someday. |

Re: EGR
If we do nothing to our card ( yes serious question ) now it has a CEL
This light is on because something is wrong why can't I just fix it with out resorting to changing my ECU? The 5 speed is not causing it I have a 94 |

Re: EGR
It's a 20 year old car. Things fail and break. If you truly want it fixed, you'll want to get a new (not used, go bend over at the subaru parts counter) EGR valve/solenoid assembly. It's a diaphragm that over time wears out and fails. This isn't rocket science...

Re: EGR
Not rocket science, but how can we tell the ecu that its all good in the egr system w/out bending over at the dealer, we are SVX ouners and that means we r really smart, correct? Lets find a way!! Will be watching and waiting and wondering and experimenting? Good day all.........G

Re: EGR
THANK YOU ! I have friends with cars 25 years older than these that have fixed problems worse than this. The car can pass emissions with the dreaded CEL.
All I want is it to go off . |

Re: EGR
you can try cleaning the carbon out, but as I said, exhaust heat and gases for 20 years take their toll on the diaphragm. There is no "putting a resistor in" to fool the ECU.

I am not sure whether putting in a resistor would work, since I'm not sure how exactly the ECU gets information about whether the solenoid is working. Here's what I would do if my 97 were having this problem: Nothing. Because in FL we don't do emissions testing and I don't mind having the CEL on. If I did have to worry about testing, I'd try cleaning out the solenoid with probably some seafoam or pb blaster. Then if that didn't work I'd try swapping the solenoid with one from my parts. And if that didn't work I'd buy a new solenoid and replace it. Because sometimes that's what you have to do.

Re: EGR
Could you explain to me how the EGR sensors tells the ECU something is wrong?
I figured it was a matter of ohms on the line, like most other sensors. So I was thinking just replace the line from the sensor with a hot wire of how ever many ohms is the normal reading. There is no sarcasm in that question. I honestly want to know why it is not possible. Last edited by Lookin4SVX; 09-17-2012 at 03:10 PM. |

Re: EGR
Next question...
How do I know that an ECU is a 92 ECU? I have 3 ECU here. 1 came in the car a 92, cali car, gives me code 56 (cali ecu). I have one from a white 92, I don't know what state it originated, but it has a 1.5ecu chip in it, and I still get the EGR codes. I have a misc one that came with a TCU I got from a pile of parts from a guy stripping a couple svx.. he didn't know which it came from. Is there some way to tell by the numbers on it? Its not big deal to me, the CEL being on doesn't bother me as long as it aint flashing. I just clear the codes then do an idle test, I don't have that OBD-II to worry about "not ready" whatever crap. :P But since I got 3 ecu here.. and a 1.5 chip.. and im still getting codes for EGR.. I would swap it if it would fix it.. But I tried 2 and both give the CEL. For all i know all ECU that came with the car, and came out of the white one, could all be replacments and not actual 92 ecu.. But I do have a 1.5 ecu chip installed.. and your saying that should override the EGR codes, and it doesn't in my 92. Last edited by Lookin4SVX; 09-17-2012 at 03:18 PM. |

I would suspect if you get the numbers off the ecu, I think its a white sticker that will tell you what year and where it was specified to be sold, ie if its a cali car or a federal, meaning all other states. One thing to note, I have read several accounts of people that have changed ecu, the intake wiring has to match the 92 ecu I guess because the 92 does not have the temp sensor wiring.

Re: EGR
Not sure how to tell the difference, sorry. Maybe nate knows.
But it's more likely that they're 92 ECUs, just because there are more 92s, and the 92s are older, and therefore more likely to be parted. When you tried the other ECU, did you get both code 34 and 56 or just 34?

I know the CEL came on, so I said screw it and put the ecu with the 1.5 chip back in. |
