How to Bypass Evap Canister

If your car has an evap canister, it’s there to capture fuel vapors so they don’t escape into the atmosphere. The canister is usually located near the gas tank, and it has a series of tubes and valves that allow the vapors to be drawn into the engine where they can be burned. However, if your car is having trouble drawing in those vapors, it can cause all sorts of problems.

The engine may run rough, or you may get a check engine light. If your car is having these issues, you may need to bypass the evap canister. There are a few ways to do this, but the most common is to disconnect the hoses that lead from the gas tank to the evap canister.

This will allow the vapors to vent directly into the atmosphere, and it should fix any running issues. Of course, this isn’t a permanent solution, and you’ll want to have your evap system checked out by a mechanic as soon as possible. In the meantime, though, bypassing the evap canister will keep your car running until you can get it fixed.

If you see any debris, remove it and clean out the canister with brake cleaner or carburetor cleaner. 3. Once you’ve checked for a blockage, put everything back together and try starting your car again. If it still won’t start, it’s time to take it to a mechanic for further diagnosis.
