What P1441 means on specific makes
Chevy / GMC / Cadillac / Buick SAFE
The PCM detects EVAP vapor flow when there shouldn't be any (during a non-purge window) — typically a purge valve stuck open. Emissions-only; may cause a slightly rough or stumbling idle if it's pulling vapor at idle.
- Stuck-open purge solenoid/valve ($30-100)
- Vent valve fault ($30-100)
- EVAP line routing/leak ($0-100)
Check first: Test the purge valve — if it's stuck open or leaking vacuum at idle, replace it.
