'97 Pathfinder - service engine soon light on. I went to autozone and they came up with

P1447 - elc system closure valve flow fault

Autozone said they have no idea and that's all they could help.
Any help? thanks

Autozone said they have no idea

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

Thanks for the reply. Suggestions to narrow it down? Where is the evap canister?

EVAP canister is behind the rear driver's side wheel.

does anyone know how much it costs to fix this code<

There are a lot of possible EVAP components that can be causing this code, see the list above. It could be as easy as a disconnected hose or multiple EVAP components that need to be cleaned/replaced. You won't be able to get any kind of an estimate until the cause of the error is investigated.

thanks for the help!!!
