On my 2003 Caravan, had the Vent Solenoid and Leak Detection Pump replaced a year ago. Two Evap codes reappeared. I just replace the Purge Solenoid and the small leak code is gone. But, I see a cracked rubber piece under my air handler and will repair that soon. The hoses to the Canister look fine. I'm not sure why that Shop didn't replace the Purge Solenoid at the same time. Thanks for your video.

I have replaced everything on mine except the vent valve ive spent over 6 thousand in parts and labor so I'm hope that will fix the issue. It's been a pain. This man is awesome in explaining thing

@WhatIs205 says:

Could this caused the stft and ltft to go all over the place?

@canocano5480 says:

What if there is no cap can the flap that closes at tank opening ever stay open?

@MM-vv8mt says:

Some vehicles will also have a EVAP leak detection pump located near the carbon canister amd the EVAP vent solenoid.
