Need a vacuum hose diagram for a 2005 Dodge Ram 1500 I found the hoses from the purge canister disconnected and one of them was melted(!), so I need a diagram of the vacuum hoses, please.

Here is a general vacuum hose and line placement diagram for a 2001 Dodge Ram 1500 4x4:

1. The vacuum line from the engine intake manifold should be connected to the vacuum reservoir tank.
2. The vacuum line from the vacuum reservoir tank should be connected to the vacuum actuator on the front axle.
3. The vacuum line from the vacuum actuator on the front axle should be connected to the transfer case.
4. The vacuum line from the transfer case should be connected to the vacuum actuator on the rear axle.
5. The vacuum line from the vacuum actuator on the rear axle should be connected to the vacuum reservoir tank.

It is important to note that the specific placement and routing of vacuum hoses and lines can vary depending on the make and model of your Dodge Ram 1500, as well as any modifications that may have been made to the vehicle. It is always recommended to refer to the manufacturer's instructions or a repair manual specific to your vehicle for accurate information. Additionally, it may be helpful to take pictures or label the hoses and lines before removing them to ensure proper reinstallation.

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.

BEST WAY IS CONNECT A GOOD DIAGNOSTIC TOOL TO YOUR CAR AND IT HAS OPRTIONS TO ACTIVATE AND TEST THEM GOOD LUCK

The electronic EGR valve and solenoid assembly is attached to the rear of the left cylinder head. An exhaust gas routing tube connects the EGR valve to the intake manifold.
1. Use a diagnostic scan tool to record any Diagnostic Trouble Codes (DTC). 2. Remove the throttle body resonator. 3. Perform the fuel system pressure release procedure (Refer to 14 - Fuel System/Fuel Delivery - Standard Procedure) 4. Disconnect and isolate the negative battery cable.


5. Disconnect the power brake booster vacuum hose (1) and the vapor canister purge hose (2) at the intake manifold.


6. Disconnect the EGR valve solenoid electrical connector (1).


7. Remove the EGR valve assembly retaining bolts (1). 8. Remove the EGR valve and the EGR routing tube from the engine as an assembly. 9. Remove and discard the metal gasket located between the cylinder head and the EGR valve assembly.


10. Remove the EGR valve routing tube retaining bolts (1) at the EGR valve assembly 11. Remove the EGR valve routing tube and discard the gasket.

You seemed to look everywhere but how about under the hood?what manufacture want to do is seperate
the check engine light from coming on due to a gas cap leak, you have at the gas tank a vent valve and in the engine area a purge valve, the most common problem besides a broken purge solenoid it self or wire and the vent solenoid and wire or canister problem is vacuum to the purge valve, its a small hose that breaks at the connection ,your hood diagram will point it out as a hose to a purge system just look at the hoses connection there is not too many there

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.

Some might have an ses p0446, evap emissions vent circuit low. If you take it to the dealer they want 300-400.00 to fix the problem. GM has a service bulletin on this condition and have the updated part for 180.00, thats suppose to eliminate this issue.

Basically the problem is, the evap purge vent valve gets clogged with dirt, especially if the truck is used in dirty conditions. Well I figured there had to be a cheaper way to cure this problem.

Here it is:
1) find the location of the vent valve; its under the truck, locate the charcoal canister on the front of the gas tank and trace the vent line to the vent valve.
2) Take the bracket loose with a 5/8 wrench.
3) Spin the valve around so the side with the hole is facing you.
4) Take an air compressor and blow the vent valve out.
5) reinstall and clear the code and it's fixed.

Now I know the updated part from gm is supposed to keep the valve from clogging ever again, but why spend the money when all you have to do is blow out the vent valve every 50k-100kmi and save your $$$!

97 Dodges have a known issue of the EVAP canister failing. The carbon granules end up clogging the vacuum lines all the way up the purge valve. Inspect the vacuum lines at the purge valve, if carbon granules are seen, then the evap canister must be replaced. Then the vacuum lines will need to be blown clean/clear with compressed air. Also then, the purge valve must be replaced or at least disassembled and clean the valve seats under the diaphragm. The top of the valve can be removed to do this. The Evap canister on these model years is mounted horizontally on the frame rail, driver's side rear of the driver's seated position. I have first hand experience with this failure with a 97 Dodge Ram 4x4 5.9L.

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.

Symptoms You likely won't notice any drivability problems.
Causes A code P0440 could mean one or more of the following has happened:

• The gas cap is not installed or working properly
• The purge solenoid has failed
• The canister is plugged and not working properly

Possible Solutions With a P0440 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:

• Remove and reinstall the gas cap, clear the code, and drive for a day and see if the codes come back.
• Inspect the EVAP system for cuts/holes in tubes/hoses
• Inspect for damaged or disconnected hoses around the Evap purge solenoid
• Check and/or replace the sensor
• Check and/or replace the purge valve
• Have a professional use a smoke machine to detect leaks
