That's probably a good thing since they didn't have the code right. P1447 on your pathfinder is a EVAP PURGE FLOW/MON error. Under normal conditions (non-closed throttle), sensor output voltage indicates if pressure drop and purge flow are adequate. If not, a fault is determined.


Possible causes:

- EVAP canister purge volume control valve stuck closed
- EVAP canister purge control valve stuck closed
- EVAP control system pressure sensor
- Loose or disconnected rubber tube
- Blocked rubber tube
- EVAP canister purge control solenoid valve
- Blocked or bent rubber tube to MAP/BARO switch solenoid valve
- Cracked EVAP canister
- Absolute pressure sensor
- MAP/BARO switch solenoid valve
