EVAP Switching Valve Control Circuit Performance
Moderate severity
What it means
The evaporative switching valve — used on multi-path EVAP systems to route purge or pressure-test flow — does not respond as expected. Self-test fails because tank pressure does not change in the calibrated direction.
Is it safe to drive?
