A small EVAP leak came from a short serviceable hose section instead of the canister assembly.
Why this matters
The value of this case is the order of evidence and the verification step. The same symptom on another vehicle may have a different cause.
Evidence to capture first
- Pressure-sensor response
- Valve sealing
- Low-pressure smoke location
- Hose material and routing
A disciplined path
- Seal the valves as specified
- Apply low-pressure smoke
- Expose the joint without damaging lines
- Install approved vapor hose and rerun the leak test
Decision point
The measured leak disappeared with the serviceable hose repair; the canister passed its checks.
