I got the p1457 on my 99 civic ex

Whats the best place to take for a diagnosis? I am located in boston, massachusetts area. Dealership quoted me $100, is it a good price? Can I trust them?

Any help is appreaciated, thanks.

any local parts dealer should be able to hook into you ECU and pull codes... many will do it for free...

take it to the zone, auto zone

they check your CEL for free

use red search button on the top for CEL codes.

Autozone is selling an OBDII scanner for $40 right now too. (Regular price is $69.99.) It's just a basic model that reads the code (no explanation on the screen) and erases codes, but it works.

It comes with a book with explanations for all the codes.

But yes, they will scan your car for free too. Then they'll give you a little print out that says what the code is, what it means and the most common problems that cause that cell.

Ok I found the problem and I replaced the 2 way valve.

Almost 300 miles passed and the light didn't go on.

Is it safe to take the test?

Thanks for the info!

How did you know it was the two way valve that was causing the problem?

I have the same code and the mechanic at the Honda dealership told me that this error would not harmfully affect my engine.

Lmao...I'm there too. How can the two way valve be tested? And where do I find one?
