Your heating and air conditioning system is controlled by the Body Control Module (BCM). Any diagnosis should begin with scanning the (BCM) for trouble codes to determine the source of the problem and/or which circuits and components are involved.

If a failed mode door actuator is, in fact the problem, the instrument panel must be removed to gain access to it.

SOURCE: What does purge or vent

This is refered to the DTC EVAP Large Leak Detected - The ECM has detected a large leak in the EVAP system during a system monitor test

Probable Cause[s]:
1. Defective, loose or missing fuel cap
2. EVAP canister broke, hose cracked or not connected
3. Purge or vent solenoid defective
4. Vacuum leak at engine

So, since you replaced the gas cap already, it sounds like checking the EVAP canister and related hoses would be the next thing to do. If there are no obvious loose or broken hoses or anything, you may have to acquire more info from a Chilton's Total Car Care or Haynes manual, or some professional-grade manual, in order to check the operation of the solenoids. Check with your local Library. Mine has online access to AllData and Mitchells, besides paper versions of Chilton's TCC you can check out. Take a thumb-drive with you, and you can save whole web pages or diagrams as needed.

A smoke machine is nice, especially if you're lazy, but hardly necessary to fix these problems most of the time. If you know where all the hoses are to check them, and how to check the solenoids, there really isn't much else left.

I hope helps (remember to rate this asnwer).

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.

I have a 97 dodge ram 2500 it is leaking fuel from fram beside the tank I know that i will have to drop tank but what is out ther that would be leaking is my Question


When it is leaking remove the gas cap, if it stops leaking your canister purge valve solenoid is bad or you have a plug line that vents the gases to the canister or from the canister to the purge valve.

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.

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.

I received the following trouble codes on my 1997 Dodge Ram 1500 with the 5.9 liter engine: 12, 31, 56 I assuime 12 is a toss away... I don't understand the description for 31 and I cannot locate 56 in my...


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.

Error codes P0442 and P0455 in Dodge Dakota 2001


Hello shoretex...Yes sir you can repair this yourself...
p0442 is medium leak detected ...p0456 is small leak....and p0440 is a general evap system failure.. evap codes are a common thing. gas caps are an inexpensive place to start. There are two types of evap hoses on the Dodge... hard plastic and soft rubber.... before you replace parts check the soft rubber first at the evap cans and pump located about a foot in front of the gas tank fill pipe on trucks located next to the transfer case or right behind the trans on the driver side. hard plastic lines will brake or rub through...check spots where lines come in contact with anything. this is a common thing with older trucks...hair line cracks will kick a p0442 code, and a p0445 code...When you find a leak, repair it, and rescan...sometimes there are several leaks, continue with inspection and repairs until you get it all fixed up.... Remember..start at simple and work from there...
i will post the evap. system in more detail to help you troubleshoot the problem.
EVAP System: The Evaporative Emission (EVAP) Control system used on all vehicles is the charcoal canister storage method. This method transfers fuel vapor from the fuel tank to an activated carbon (charcoal) storage device (canister) to hold the vapors when the vehicle is not operating. When the engine is operating, the fuel vapor is purged from the carbon element by intake air flow and consumed in the normal combustion process. The evaporative system includes the following components: *Fuel tank *Evaporative emission canister vent solenoid *Fuel tank pressure sensor *Fuel pipes and hoses *Vapor lines *Fuel cap *Evaporative emission canister *Purge lines *Purge valve solenoid EVAP System Operation: The EVAP purge solenoid valve allows manifold vacuum to purge the canister. The Powertrain Control Module (PCM) supplies a ground to energize the EVAP purge solenoid valve (purge on). The EVAP purge solenoid control is Pulse Width Modulated (PWM) or turned on and off several times a second. The EVAP canister purge PWM duty cycle varies according to the operating conditions determined by the mass air flow, the fuel trim, the engine coolant temperature, and the intake air temperature. For certain EVAP tests, the diagnostic will be disabled if the TP angle increases to above 75% . The evaporative leak detection diagnostic strategy is based on applying vacuum to the EVAP system and monitoring for vacuum decay. The fuel level sensor input to the PCM is used to determine if the fuel level in the tank is correct to run the EVAP diagnostic tests. To ensure sufficient volume in the tank to begin the various diagnostic tests, the fuel level must be between 15% and 85% . The PCM monitors the fuel tank pressure/vacuum level via the fuel tank pressure sensor input. Results of Incorrect Operation: Poor idle, stalling and poor driveability can be caused by the following: *Malfunctioning purge solenoid. *Damaged canister. *Hoses/lines split, cracked and/or not connected properly. Evidence of fuel loss or fuel vapor odor can be caused by the following: *Liquid fuel leaking from the fuel lines *Cracked or damaged canister *Inoperative canister control valve Vacuum hoses that are: *Disconnected *Mis-routed *Kinked *Deteriorated *Damaged The evaporative leak detection diagnostic strategy is based on applying vacuum to the EVAP system and monitoring vacuum decay. 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 small leak in the system causes DTC P0442 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. Any of the above conditions sets DTC P0440. A restricted or blocked EVAP canister vent path is detected by drawing vacuum into the EVAP system. The PCM turns off the EVAP vent solenoid and the EVAP purge solenoid (EVAP vent solenoid Open, EVAP purge PWM 0% ). The PCM monitors the fuel tank pressure sensor input. With the EVAP vent solenoid open, any vacuum in the system should decrease quickly unless the vent is blocked. A blockage is caused by the following conditions: *Faulty EVAP vent solenoid (stuck closed). *Plugged, kinked, or pinched vent hose. *Shorted EVAP vent solenoid driver circuit. *Plugged evaporative canister.

Good luck shoretex, hope this helps...please take time to rate me a fixya.

Does the Purge Solenoid run continuously?


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