10 Chrysler ESIM Leak Detection

[@tt-rs1457]

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.

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.
