Merry Christmas to everybody.
I am having a problem with the check engine light coming on, code P0446. So far I checked the purge valve, the canister close valve, the one way valve, the filter and the vent pipe. All is ok, did vacuum test and used 12v to check the solenoids, also just for kicks I replaced the gas cap. All is working but code still coming on. There was a repair that was made to the plug on the canister close valve but I checked continuity and is all ok, I blow the lines with an air can, gas came through the pipe. I am suspecting the ECM now. Is there anything else to be done ?
Thank you for your reply.
