hi i have a 1999 honda accord ex 4cyl ulev i saw many of the other posts but i had noticed when i got my light on about a month ago due to p1457 i noticed that every time i fuel up the gas pump resets and i have to get out and re start the gas pump handle. any ideas? on what that could be? i saw many posts that its the vent shut valve. i didnt know if that problem would help diagnose that problem any easier... and i also read that it could be caused by over filling the tank. beieve me i could never afford to fill the tank let alone over fill it to cause this peoblem. i live in nj and yes they use salt on roads.. any help would be great.

The DTC P1457 can be a number of things causing it; but, probably due to failure of the EVAP Control Canister Vent Shut Valve. Here is the TSB:

No, but by filling it too quickly (and having the fuel belch back and trip the filler handle) could effectly set a code...
Try filling the tank slower and see what happens

The canister vent shut valve or the EVAP Bypass Solenoid Valve could be the problem, as the culprits easily get corroded in geographic locations that use a lot of salt on the roads in the winter. Honda had to redesign the parts to address this problem.

TSB's ( Technical Service Bulletin's ) 01-011 ( EVAP Control Canister Vent Shut Valve 98-99 models ) and 03-001 ( EVAP Bypass Solenoid Valve 98-02 - depending on the model ) address these problems and explain that if left unchecked could damage the PCM ( computer module ). It has nothing to do with the gas cap as that would be a P1456 code.

If the car is a 97 Honda, the warranty on the emissions system has been extended to 10 years or 150,000 miles. See TSB 98-081 (97 only ).

The EVAP Control Canister Vent Shut Valve is easy to find and replace youself. And if your lucky and can persuade the Dealer to fix it, they can replace it using goodwill ( free ). They don't do it always, but it can't hurt to ask. This is also mentioned in the TSB's.

But if you want to do it yourself, and it may take less time than bugging them, and is fairly simple. Just be careful of the two screws that hold it ( EVAP Control Canister Vent Shut Valve ) in place as they are probobly badly corroded. Spray them with some break free, if they give you a hard time, rather than taking the chance at snapping them. But you won't know till you look at them, they may just come right out, but i just wanted to warn you. The bottom of the car get abused by all the rain and salt it is exposed to over the years.

I have all the TSB's as well as EVAP/ fuel system diagrams, if anyone needs them just contact me. The TSB's have good diagrams as well and show you a lot of detail.

Good Luck!!!
