I had the unfortunate luck of grabbing this as my first video to describe the operation of the ESIM. I was totally confused because THIS VIDEO IS WRONG. The diagram shown SHOULD HAVE the charcoal canister/fuel tank on the left side and a filtered vent to the atmosphere on the right, but it doesn't. It would have been simple enough to say that the ESIM is a pressure relief valve that contains evaporative emissions below a certain tank pressure, allows air back into the fuel tank below a certain vacuum, and has an electrically monitored pressure switch to verify there are no system leaks. Please fix this video. Thanks in advance.
Sir,
what will cause the P0441 (purge flow incorrect)
Will it the switch from the ESIM , that won't close or will stuck close all the time ?
Very informative, thank you very much for posting this explanation of a part that seems to go bad often.
