Re: Extended emissions warranty for 1998 Civic?
Yea, but for Christs sake, electronics should be built with protected circuits, but I understand engineered obsolesce and making these as cheap as possible or I guess just a plain old design flaw... at the very least with all the articles on P1457 errors, you would think Honda would have addressed this...

Re: Extended emissions warranty for 1998 Civic?
Or, you know, an isolated incident. I've very rarely seen a Honda ECU go bad.
Btw, if you think that's bad dodge used to put the voltage regulator for the alternator in the ECU. When it died (and they did, we had it happen on a '91 Dakota) you had to replace the ECU, or wire in an external regulator (what we did, but it still left us with a CEL for the bad voltage regulator) It was otherwise a great truck though, one of the most reliable vehicles I've ever seen.
Sorry for the offtopic rambling.

Yea, I guess. Another member sent me some other diagnostics to look at, may give it a try...

@ the OP
A good used ECU isn't that expensive if you DO have to get a new one, so don't fret too much
http://www.ebay.com/sch/i.html?Model...p3286.c0.m1539
Heck, I got mine for my mini-me swap a while back for $20 + shipping and it's running just fine a year later
Just gotta shop around

Re: Extended emissions warranty for 1998 Civic?
Exactly. Although I do remember now when I worked at Honda the oldest tech there mentioned this code to me. It was common when those cars were fairly new and it took the ECU out every time. I'd kind of forgotten about that. Still at this point, it's your car problems and all.

Re: Extended emissions warranty for 1998 Civic?
I was wrong. The extended warranty appears to cover 95-97 Civics:

Re: Extended emissions warranty for 1998 Civic?
My 97 hx was covered. The warranty is good for 14yr/150k miles on emissions and only on select models. The dealer replaced my primary o2 sensor, free tune up & oil change, cleaned egr ports, and replaced the ecu all under that warranty.
Which model do you have so we can try and help you fix it.

Re: Question on diagnosing a P1457 EVAP system problem
Thanks Ron for your help. I replaced the old ECU with a virgin one. I looked at the insides of the old ECU and did not see any burnt traces, which does not mean a whole lot... Anyways, I installed the unit and no CEL.... but it did come on two days later, but now I have code P1456. Gas cap was tight, but I tightened it a little more. I know the tank was almost out of gas. Could the CEL have been thrown due to the issues I had with the P1457 code, and a low gas tank? Maybe a pressure issue that should resolve when I cycle a full tank? Please let me know your thoughts. Thanks.
FYI - as related in this post all components/solenoids around the tank have been replaced with OEM parts...

Re: Question on diagnosing a P1457 EVAP system problem
Yes. I remember when I worked at Honda one of the older techs mentioned that to me. Apparently it always takes out the ECU, he told me they replaced a ton of them under warranty when those cars were new. Sorry I know this is kind of past the point now, but I just thought I'd put it in here anyway.

P1457 CEL light came back on
Or someone else... I had a long thread about the problem, and ended up getting a virgin ECU. I noticed that as soon as I installed the new ECU that the tank was empty and I got a P1456 CEL. I cleared that and now today, with the tank almost empty a CEL came back on. The CEL is P1457. Does that mean that the ECU I bought is burned????? I don't know where to go from here. I replaced all the solenoids and valves that are by the rear gas tank. The only items I have not replaced is the solenoid (not sure of name) by the fuel injector rail and the evap canister and valves. Does anyone know where to start with this????????????? Thanks!!!!!!!!!

Re: RonJ@HT - P1457 CEL light came back on
theres a tsb regarding this. if your a regular honda customer you could ask for a goodwill
as for the ecu--not knowing your story---it means you didnt fix the problem. The ecu is most likely fine. Then again...I have no idea of your post/backstory
1456/57 is for the vapor canister...
as far as I know theres 3 valves associated with it...how many did you change? are you in the rust belt? Usually people replace all 3 valves and the canister because they usually fall like dominos. Being in the northeast, this is much more common.
As for solenoids/valves...you might want to say what you did, for the people that dont know like me or anyone else reading this. That or just PM ron.

Re: RonJ@HT - P1457 CEL light came back on
I just read your post/backstory---makes alot more sense now. It would make sense that the ECU went out.
If you did all the troubleshooting tests and tested the solenoids/valves, and it pointed to the ECU, chances are you might have gotten a bad one. That or your going to have to recheck your work. Here in the rust belt, these solenoids go bad more frequently. In the honda TSB it states, more affected in snow areas, funny that your out west.
If the car has 86k like you said, Id call up various honda shops in the area, and explain the situation. Bitch a little to honda north america or district managers helps, being a good customer at the dealership though helps more. Buying parts at majestic honda and working on your car yourself...not so much-
From the last post, Id re do the service manual instructions to trouble shoot. I remember that using all autozone parts for solenoids/valves was about $300, so its cheaper to troubleshoot then it is to replace parts.

Re: RonJ@HT - P1457 CEL light came back on
I used to work for a dealer...I **** you not, at least 60% of the cars we worked on, all overfilled with gas. where I live, its mostly for us full serve, and they round up (for the sale)--not that the gas station attendants care.
No joke..we did so many canisters/solenoids/02 sensors/ecu's that we had 50 in stock at all times. Every single one would come up on the computer as canister malfunction at 0 mph. Or in other words...stupid broad rounding up the gas. We'd ask the customer, did you stop when the pump stopped or did you round up? Everyone stopped....or so they said. They also left 1500 bucks with us for new canisters etc.
One customer did it 3x in the course of a 2 month span. Guess he didnt believe us. 1x we did a goodwill on it...2nd and 3rd time he paid. The 3rd time he only agreed because his tags were up---no inspection with a CEL. Dumb old man, spent a fortune because he wanted that extra 75cents of fuel in there.

Rounding up takes out canisters. *its where that extra gas heads to when we round up*

Thanks. So what are you basically saying? Do I need to get another ECU? Or is this a canister issue alone or the solenoids?? Etc???? Thanks again!

Re: Question on diagnosing a P1457 EVAP system problem
was this ever resolved? i have a 96 civic ex and its had the CEL light on ever since i bought it..pretty much a yr or so and its my DD and it goes away if i reset the ecu..but comes back in a week or so..and i make sure my gas cap is tight..anyways the code mine throws is P1457: Evaporative Emission (EVAP) control system leak detected (EVAP control canister system)...and now its nice out when i drive with my moonroof open i can smell gas under acceleration not sure if its due to the P1457 code or not...

Re: Question on diagnosing a P1457 EVAP system problem
^ no....I just read from the OP he changed the ECU and was still having a problem. I mentioned that I used to work at a dealership and we would change charcoal canisters like we'd do oil changes.
