I didn't find this link until after I had already disassembled my truck. This is the hardest job that I've taken on thus far, hope I can put it all back together properly. I changed the gaskets on the valve covers since I had everything off.

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
