The EVAP purge valve pulls fuel vapor from the gas tank and sends it into the intake manifold. From there, it burns off cleanly. Your Ford’s PCM performs a test on the EVAP check valve during light boost conditions, one time per drive cycle.

The evaporative emission control (EVAP) system does not prevent fuel vapors from escaping into the atmosphere, according to code P0441. When the purge valve is set to P0441, however, the check engine light code does not properly regulate the flow of fuel vapors by allowing too much or too little flow.

The air/fuel vapor mixture continues through the EVAP purge pipe and EVAP purge valve into the intake manifold to be consumed during normal combustion. The EVAP system requires the PCM be able to detect a leak as small as 0.040 inch in the EVAP system. The PCM uses several tests to determine if the EVAP system is leaking.Faulty Purge Flow Sensor: The purge flow sensor itself may be malfunctioning, leading to low input signals. Wiring or Connector Issues: Damaged or corroded wiring or connectors can disrupt the proper signals between the sensor and the engine control module. Vacuum Leaks: Leaks in the vacuum lines or fittings of the evaporative emission system can interfere with the sensor's performance.The EVAP canister purge check valve test is performed during minimal boost conditions, once per drive cycle, when entry conditions are met. The DTC is set if the fuel tank …After my engine light and TRAC OFF light came on, I have two confirmed two PID codes on my 2012 Tacoma / 4.0 L that indicate there is a problem existing with the Evaporative Emission system.
