pulled this off my son's truck...P0441- Evaporative Emission Control System Incorrect Purge Flow. any one know what this means?
CHECK ENGINE LIGHT CODE ON 2003 RAM?
- Thread starter SANCHOBA
- Start date
1- loose or broken from your evap system or canister
2- stuck open purge solenoid
3 - Possible gas cap off
4 - vacuum lines reversed/come loose
5 - EVAP cannister/lines clogged with carbon
Rams both Hemi and Viper have had loose gas caps believe it or not.

okay...thanks. going to look the system over
Good possibility its the Natural Vacuum Leak Detection Assembly. It is located near the front of fuel tank. PM me a fax # and I'll fax you test procedure. Won't hurt to drive, your fuel tank fumes may not be going where your Goverment wants them to go. What size engine? Have you replaced any parts trying to fix it yet? ( Its easy to mount the Purge solenoid upside down)
P0442-is detection of a leak..... (like a cap),i have P0441:dontknow:
found this.....The "EVAP purge flow" faults are issues between the carbon Cannister and the intake. The evap leak detection generally concerns the fuel tank to carbon Cannister plumbing

[QUOTE=,i have P0441
P0441 EVAP Purge System Performance
Setting Conditions
Engine started (cold);ambient air temp 39-89F at startup,fuel level sensor over 12%, small leak test has been passed, and then the EVAP purge solenoid is activated to increase the purge flow. If the PCM detects the NVLD switch does not close under maximum purge flow, DTC P0441 is set. This code sets after two trips.
Possible causes
EVAP purge valve vacuum supply is leaking or too low
Purge solenoid or connector is damaged
Purge solenoid hose pinched or restricted ( fuel or charcoal )
Sticking switch in NVLD
