I have a code P1447
P1447 - Evaporative Emission (EVAP) Control System, Purge Flow Monitor
In this evaporative emission (EVAP) control system, purge flow occurs
during non-closed throttle conditions. Purge volume is related to air
intake volume. Under normal purge conditions (non-closed throttle), the
EVAP canister purge volume control solenoid valve is open to admit purge
flow. Purge flow exposes the EVAP control system pressure sensor to
intake manifold vacuum.
Under normal conditions (non-closed throttle), sensor output voltage
indicates if pressure drop and purge flow are adequate. If not, a fault
is determined. Malfunction is detected when EVAP control system does not
operate properly, EVAP control system has a leak between intake
manifold and EVAP control system pressure sensor.
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
Possible causes
* EVAP canister purge volume control solenoid valve stuck closed
* EVAP control system pressure sensor and the circuit
* Loose, disconnected or improper connection of rubber tube
* Blocked rubber tube
* Cracked EVAP canister
* EVAP canister purge volume control solenoid valve circuit
* Closed throttle position switch
* Blocked purge port
* Closed throttle position switch
