Trouble Code P1447 - Evaporative Emission Control System Purge Flow Monitor
Possible faults which could cause your Nissan Maxima to set OBDII trouble code P1447 include:
- EVAP canister purge control solenoid valve stuck
- EVAP control system pressure sensor and/or circuit fault
- Loose, disconnected or improper connection of vapor hoses
- Defective EVAP canister
- EVAP canister purge volume control solenoid valve circuit - Blocked purge port
- Closed throttle position switch
Ensure your Nissan Maxima's EVAP purge solenoid is functioning properly. By applying 5 - 9 volts you should here a click indicating the solenoid is working. The system sets a P1447 when there is an electronic problem involving one of the EVAP sensors or solenoid, or when the EVAP control system finds a leak between intake manifold and your Maxima's Charcoal Canister.
Note also the EVAP system only purges when you're driving and on the throttle. If the TPS (Throttle Position Switch) is defective the ECU will set a P1447.
