What does this code P0441 mean for engine light on 2004 dodge ram 1500 truck?


2004 Dodge Ram 1500 Truck Code P0441 indicates that a part of the EVAP control system is no longer functioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
EVAP emission canister purge is controlled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank into the engine to be burned, rather than be vented to atmosphere. A vacuum switch is used to detect when flow exists. If the PCM commands purge and sees that the switch is closed (indicating no detected purge flow) P0441 is set.

Symptoms :

Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light.

Causes :

A code P0441 could mean one or more of the following has happened:

Bad vacuum switch Broken or damaged EVAP line or canister Open in PCM purge command circuit Open or short in Voltage feed circuit to Purge Solenoid Faulty purge solenoid Restriction in EVAP solenoid, line or canister Corrosion or resistance in purge connector Bad PCM

Possible Solutions :

With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try: Common Chrysler fix - Replace Leak Detection Pump / LDP Repair damaged EVAP lines or canister Repair open or short in voltage feed circuit to Purge Solenoid Repair open in PCM purge command circuit Replace purge Solenoid Replace vacuum switch Repair restriction in Evap line or canister or solenoid Repair resistance in purge connector Replace PCM

I hope this helps.

P0441 code and blower issue


These two issues are unrelated. The P0441 code is an evaporative emissions control issue. If the hoses they replaced were part of that system you'll have to recheck them. The purge solenoid, also part of that system and a frequent cause of that code, should be replaced as well.

The blower issue is most likely related to a faulty/bad blower motor resistor. The lonk below illustrates the removal procedure for a 2001 Durango, check yours to see if it's the same.
