I am getting engine code "P1441" and it means "Evaporative Emission System Flow During Non-Purge". Can anyone tell me what the problem might be? Sounds like a problem with the EVAP system that purges the gas fumes from the tank into the charcoal cannister. It could be EVAP purge valve going bad or it could even be a blown fuse from the circuit.Pump down to 20" vacuum and make sure it will hold for about 30 seconds. If the vacuum doesn't hold then there is a leak in the line going to the purge valve or the purge valve is bad. 5. Reconnect the vacuum hoses with their spring clamps. Reattach the throttle cable (if applicable) and replace the engine cover.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.
