Welcome Aubie. The Vent valve is only part of it. The filter in the valve was not good enough and it allowed dirt to get into the system and it plugs the canister. The good news is you may not need to replace the canister. We have had great luck cleaning the canister out. What we do is remove the canister and put low pressure compressed air into the small line in bursts while tapping around the entire canister with the handle of a screwdriver. Do this outside as there will be lots of dust and it will be very messy. I keep tapping and blowing until there is not dust. Then you will need to get the code cleared. Did you install the updated valve?

Yes I installed the updated vavle recommended in the tsb. The canister you are talking about is at the front of the tank right?

Expert:  GM Tech (Cam) replied 5 years ago.
The canister is has 3 hoses, all different sizes going into it. That area was the change over so its is either directly in front of the tank or above the drive shaft on the right side of the tank.
