The purge solenoid only runs when the computer turns it on, not all the time.

    If the purge solenoid is bad the check engine light will come on. Other than that you may never know. It will not affect anything else.

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.

Location of purge solenoid on a 97 dodge ram 1500


I had to change a purge shutoff valve on my car it was in the rear of the gas tank. I'm not sure if that's what you mean but good luck.

2003 Mitsubishi Eclipse has a P0456 (sometime RD - pending) Evap small leak. Replacing gas cap did not solve. Is there a vapor canister purge valve/solenoid on this car?


There is a purge valve and solenoid on most cars I believe. The purge valve is usally located by the engine and the selenoid is usally located by the fuel tank. Call up or go visit your dealer and you will be able to order the parts from them and they can tell you the exact location.

My engine light is on . I have a code # E-0455


The PCM monitors vacuum level via the fuel tank pressure sensor input. At an appropriate time, the EVAP purge solenoid and the EVAP vent solenoid are turned on, allowing engine vacuum to draw a small vacuum on the entire evaporative emission system. After the desired vacuum level has been achieved, the EVAP purge solenoid is turned off, sealing the system. A leak is detected by monitoring for a decrease in vacuum level over a given time period, all other variables remaining constant. A large leak in the system causes DTC P0445 to be set.

If the desired vacuum level cannot be achieved in the test described above, a large leak or a faulty EVAP purge solenoid is indicated. This can be caused by the following conditions:

*Disconnected or faulty fuel tank pressure sensor.

*Missing or faulty fuel cap.

*Disconnected, damaged, pinched, or blocked EVAP purge line.

*Disconnected or damaged EVAP vent hose.

*Disconnected, damaged, pinched, or blocked fuel tank vapor line.

*Disconnected or faulty EVAP canister solenoid.

*Disconnected or faulty EVAP vent solenoid.

*Open ignition feed circuit to the EVAP vent or purge solenoid.

*Damaged EVAP canister.

Check engine light on.Took truck to checkers and it was put on scope and results came back with EVAP canister broke, and purge or vent solenoid defective and vacuum leak at engine also failed tcc or...


The codes you are getting can be caused by one of the several parts to the canister purge valve. It would best be taken to a mechanic or you may be replacing parts that you don't need. Normally the evap canister purge valve has stuck or broken or disconnected.

2004 dodge ram 1500 w/5.9 check engine light is on replaced gas cap, still on where is purge solenoid or what else could be problem. also cant find evap canister


Good luck! does it say if it is a large or small leak in the evap? Purge cannister is either underneath the box by the fuel tank or under the hood on the rad support I think. This is a pesky little annoying problem. I would ask around to see if you know a good shop that can look at this for you, you need speacial tools to test and diagnose

code 31 is the evap system, the fumes from the tank, the computer can seal or vent the vapors, and so its telling you theres a big leak its not able to seal, could be a loose or bad gas cap or a broken vacuum line for the system or a vent or purge valve went bad,code 56 is not a code, double check . good luck,hope this is helpful.
