Evap Error code P1457 on Accord

[safristi]

 so BASICALLY wot U R sayin' is don't Give Kar Kodes any RESPECT...cos they are useless..........OR your Accord is from NEBULON the Galaxy far beyond.... .....

Well the story continues but is nearing the end.

My mechanic brought my car to Honda for testing. They sent a signal via car's computer (PCM) to open and closed vent solenoid to see if computer was working. Their testing comfirmed the computer is fried and will have to be replaced.

As these computer rarely fail in Honda's, my mechanic is going to find a 2nd hand one. He figures he can get one for about $300.00. I am getting it fixed next week.

When the light first came on months ago I had just moved to a new house and was up to my eyeballs in bills. My mechanic told me the repair of evap system could wait and would not harm anything. In hindsight I think delaying repair (and having stuck valve) may have cause computer to fry. It turned a small problem into a big one.

It has been my first bad experiance with my mechanic how has given me years of great service.

I never delayed a repair before and I will never do it again. Lesson learned........

I highly, highly, doubt that.

Interesting they finally found the source.

Like Artic I can't see not fixing the valve frying the computer.

Can someone tell me where PCM (computer) is located on my 2000 Accord. 4 cyl VTEC.

There is a TSB on this fault. The resistance of the solenoid drops below 20 ohms. When the PCM sends the ground to activate the solenoid, it creates a short that damages the PCM.

I recommend your mechanic check TSBs before every repair. It saves alot of time and parts 

Good Luck

ps. The PCM will require a reflash before it can be used in your car.

Any idea what the TSB number is that has these details. Can I get a copy off the internet?

Also I assume that the fact that there is a TSB does not mean that Honda will cover repair under warranty.

Can anyone help me find TSB that mentions the problem stated above. I sent poster a PM but got no response. He has only done one post so he may never be back.

Relate to Evap system error 1457 on 4 cyl 2000 Accord

Thanks in advance

Dealer has all the TSB's and some pay sites will give you access, like AllData.  But, Honda limits access at those sites.  Look what I found using Google and 5 seconds of my time...

the attached message from a Honda Dealership was alarming. Please read: Please note that the # is from a dealership in Ohio and not to call( Unless that you really want to ):



“CHECK ENGINE” or “SERVICE ENGINE SOON” light on the dash:

It has come to our attention through automotive trade publications1 that some Honda vehicles are susceptible to internal corrosion of the EVAP control canister vent shut valve. This corrosion is caused be salt-laden water in Snow Belt areas finding its way into the internals of the canister vent shut valve. Honda has released an updated EVAP control canister vent shut valve to address this problem. But, as far as we know Honda does not have a recall to address this problem. Sometimes, if you wait until the “Service Engine Soon” light on your dash turns on it could be too late, because sometimes when the old valve shorts out internally, it could zap the PCM (Powertrain Control Module or car computer) in the process. Then you would need to replace the computer to solve the problem, which could be very expensive.

If you would like to contact us for further information, please call (614) 262-1426, or to set an appointment to replace the original valve with the updated one. That can save you all the diagnosis charge and the cost of potential car computer damage.

These are the vehicles often prone to this problem:

1998-2000 Civics
1998-2001 CR-Vs
1998-2002 Accords
1999-2003 Odysseys
2000-02 Insights
2000-03 S2000s
2003 Pilots

*** update ****

The TSB exists and  it mentions that PCM can be damaged due to corrsion in valves cause shorts. Because of this I decided to give Honda Canada a call to see if there would be some goodwill extended to help me in replacing my PCM.

I had  7 year extended warranty but that had ended. Well it turns out that the PCM is warranted to 8 years or 130,000 Kms. I had no idea.    I have 79,000 kms and also have a few months to go before the 8 year mark.

I went to dealership with all my service documentation and the service rep looked into it. She called me back and gave me an appointment for next Thursday to have PCM changed. I have to say she treated me very nice considering I do not do servicing there.

All the testing and re-testing along with changing the 3 valves / solonoids in evap system cost me over $500 at my mechanics. This might have been one time I would have been better off going to dealer for repair as I think they are better eqipped for testing this system.

But pretty thrilled at prospect of getting my PCM changed under warranty. I can hopefully put this nightmare behind me.

[PJungnitsch]

  That's a nice surprise! In mechanics it's very rare for something to cost less than you expect.

[Auto Expert]

Hi Sly,

I have been away and unable to post till now, I see you have it all worked out.

"This might have been one time I would have been better off going to dealer for repair as I think they are better eqipped for testing this system"

The above statement may be true in your case.  "Your mechanic" needs more training and a proper repair data information system for his shop.

Remember it was an Independent, non dealer technician that first told you about the TSB.

Good Luck

[slybry]

PCM was changed on 03 July at no charge. They treated me quite well I must say.

So far I have gone 150 kms without light coming on. I am hoping this is the end of this problem.

Great that I had warranty but disappointed that dealer did not advise me of this when I went to speak to them about the problem long ago. Spoke to service rep and head technician.

If I had not called Honda Canada for some goodwill I never would have known.

This experiance has left me a little unhappy with both my mechanic and the dealer (for different reasons).

Now bringing my Acura in to my mechanic to get shift linklage cable changed (question on another thread about this). Hopefully this will go well and restore my faith in him.

I stumbled across this forum while researching the 1457 code, and reading over this thread, I noticed several people jokingly say just drive the car. Well, in all seriousness, would that be all right? Say that someone isn't planning on selling or trading the car, and it's living it's life as grunt vehicle. Would not repairing this 1457 code damage the car? The reason I'm asking is I don't really want to throw a lot of money into the car unless I have to. The light  initially came on on a Monday, and we had the code ran, and were pretty much told to tighten the cap up. 3 days later, the code was back. So we bought a new cap. Now, 3 days later, that's right. Check engine came back on. I guess what I mean is how serious is this as far as potential long term damage to the Accord? She's a 99 with 135,000 miles, and I'm not planning on getting rid of it until it falls apart. Would it be fine to just drive?

All thoughts would be appreciated. Thanks.

Ghost of Sparta Welcome to the Forum. I would suggest to you to have this problem diagnosed as it may not be the very same thing Slybry had wrong and something cheaper or easy to fix even. Until you have a positive answer I would not just assume its the same thing. 

[slybry]

Like Barrie said your problem may not turn out as bad as mine. But here is my advice to you.

I drove the car with check engine light on for a couple months to delay expense. I can not help but think that not fixing it right away led to burning out my computer (pcm). I would nbot delay repair.

The problem may be cause by the failure of one of these 3 components in the evap system.

- Purge Control Solenoid
- Vent solenoid
- By-Pass Valve

I think they are checked by sending a charge to them and listen to hear if they are clicking and there for operating.

What my mechanic did not have was a machine to send command to open and close these valves through the PCM. This way he could have confimed that the PCM was sending proper commands. He change the bad parts and the check engine light came on because the PCM was not sending the signal to the new valves.

I would go to a shop or dealer that have eqipment to test PCM. I would first have components tested. Change the faulty one and before taking car back have them send signal via PCM to new component to ensure PCM is working.

Could be just one bad component. They each cost about $100 plus labor. If PCM is bad it is expensive. They run about $1000. If your dealing with a local shop maybe they can find a used one. I was told used they run about $300.

I hope your PCM is OK.

I don't know if the PCM fixed your problem but in all the p1457 DTCs I've seen(I'm an Acura tech and was a Honda tech) its been due to the canister vent shut valve leaking to the atmosphere from where its clamped together, not at where it connects to the canister or any of the hoses. The easiest way to test is spray soapy water all over the CVS(canister vent shut valve) and spray compressed air into where the largest hose connects to it. You'll see bubbles coming out from the seam where the two halves of the CVS join.
You usually have to replace both the CVS and the canister.
This is a super common problem with '98-'02 accords and similar year acura TLs even some ELs.

Bad bad bad!!!

I got the same frightening code P1457 on my Accord DX 2000.  The car was imported from Canada to US 7 years back.  It got 150K km on it.

I tight the fuel cap and did hear the pressure sound though.  I got the scan from Autozone for free, bought a new Canister shut valve for $50 and have it replaced by a local machinist.  The machinist told me that old valve is still good (surprising), but I instructed him to replace it anyway (one screw was broken during replacing due to rusting).  The code was cleared by him using the hand hold devices on Oct 6, 2009.  I will wait and see if the code come back again or not.  Just hope the chip was not fried.

[accordproblem]

Just an update.  It is still good.  The light is still OFF so far Nov 2, 2009.  Hopefully, that is it.

BTW, I also added1.5 L of engine oil since it was so low when the light showed up.  I wonder if the long distance high way driving of 1500 miles consumed some engine oil.

So possible reasons: 1) shut valve 2) engine oil low
