A result applies to the section included
The GoTech article describes bypass and isolation valves that allow sections of the EVAP system to be tested separately. A tank-section result therefore cannot establish the condition of a section excluded by that valve state. The names, layout and test sequence must be matched to the vehicle.
- Tank section
- Isolation / bypass boundary
- Remaining vapor path
| Before interpreting a result | Why it matters |
|---|---|
| Identify the tested section and valve states. | An isolated section can be outside the current test. |
| Locate the connection and pressure feedback in the application diagram. | A reading only describes the connected test scope. |
| Record which sections still need evidence. | A passing section does not establish a whole-system pass. |

Match the explanation to the vehicle
Confirm the system diagram, required operating conditions and exact monitor description. The source does not establish verified thresholds, timing, wiring or application coverage for your vehicle.
