What P1443 means on specific makes
Heads up: P1443 is a manufacturer-specific code, so the same number means different things by make.
Ford / Lincoln SAFE
Fault in the EVAP purge control solenoid or valve — it's not flowing purge vapor correctly. Emissions-only; drives fine. Can sometimes cause a slightly rough idle if the valve sticks open.
- Stuck/failed purge solenoid ($30-100)
- Cracked/blocked purge line ($0-50)
- Wiring fault ($20-100)
Check first: Test the purge solenoid for sticking and proper command response; inspect purge hoses.

Subaru SAFE
The EVAP vent control valve function is faulty — the valve that seals the EVAP system for leak monitoring isn't operating correctly. Emissions code; drives fine but fails EVAP monitor.
- Failed vent control solenoid/valve ($40-150)
- Clogged/cracked EVAP lines or canister
- Connector/wiring fault
Check first: Actuate the vent valve and smoke-test the EVAP system; check the canister and lines (corrosion/road debris common on Subaru rear-mounted canisters).
