Default i have a 98 honda accord with check engine light p1457?

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

No they have had to have seen this issue before and tested the ecm before putting all those new parts on.Sounds like they dont know what they are doing the car is 12 years old you cant tell me they have never come acrossed this before.

Yeah, sounds like they're a bit confused.















I know that code is specific to the EVAP canister system. I would have told them to only replace the EVAP Canister and hoses for the canister first and left it at that, then wait for the code to come back if it did.































You should question them and ask why they didn't make sure the ECM was communicating with the solenoids FIRST, before making you take their guessing route to solve the problem.















And, why in the world would they have only just now figured out there was an ECM issue if they told you they did an electrical test, sensor test, and smoke test in the beginning and found everything to be good?































I just hope you really had a P1457 code and not a P0457 code, cause the P0457 is just simply a loose gas cap lol.
