DIY(初級）HONDA CODE P1457 修理記

我的 ACCORD 2000 check engine light on。這是煩心事。 查CODE是 P1457, 把code消掉，第二天又亮了。上網查了一下，是EVAP問題，還挺多的。

這有時也挺坑人， 如下麵：

I have a 98 honda accord with check engine light p1457 regarding an evap leak. i went to the dealer and they did an electical check , checked the sensors and did a smoke test. they told me all the sensors worked fine and electrical check was good and did not see any smoke when they did the smoke check.then they told me they wanted me to change the canister, Purge Solenoid Valve ,2 way valve bypass solenoid valve and and shut off valve. which i did it cost me over 800 dollars labor and parts included

after it was all done they come to me and tell me that my ecm is not getting communciation with the bypass solenoid valve and i need to replace the ecm and it would cost 1200 dollars. they took me to the car and showed me that their was supposed to be a double knock on the bypass solenoid so it can get a signal to the ecm

did honda dealership do their job right regarding this problem and should i buy an aftermarket ecm to fix this problem they tell me... please give me answers and suggestions 

網上有人說，
1. 90%的可能是CANISTER VENT SHUT （CVS）Valve 壞了，要換；
2. CVS 連在 CANISTER 上， 必須一起拆；
3. 50%的可能是 CVS拆不下， 最後必須連CANISTER一起換。
4. Canister 極少會壞，換了也白換。

估價： CVS $34, CANISTER $80.
看了下麵的vedio， 覺得可以賭一下。 先買了CVS valve。

CVS和CANISTER在車底下，左後輪的地方。 先把車倒到兩個架子上麵， 拉上手刹， 前輪頂上三角木。
鑽到車底， 拆掉連接的四根橡皮管和一個電插頭，拆掉一個固定螺釘，CANISTER就掉下來了。
下麵把CVS valve從CANISTER拆下來， 一個螺釘拆開， 一個拆不開。 加了WD-40, 等了一個晚上，還拆不開。原因是螺釘與底座鏽在一起，螺釘與底座一起轉。隻好到 ADVANCE AUTO PARTS 去買個CANISTER， 花了$60 (減20 coupon）。
裝回去比較簡單。
到現在一個星期了， 燈沒再亮。 希望修好了。
鑽車底有危險，自己小心。
請指教。
