Hello!
I’m hoping someone can advise or help me with my “check engine light” code P0441 – ” Evap. Emission Sys. incorrect Purge Flow”.
I have a 1997 Dodge Ram 1500, 5.2L, V8, w/ 131K miles.
I disconnected and checked the lines from the charcoal canister to the purge valve and from the purge valve to the intake. I checked them physically and by blowing air through and putting pressure into them – all good. Next I checked for a loose elect. connections and that was good. I back-probed the solenoid and once it warmed up it gave me a fluctuating reading of .925 – 1.000V across the blk. and red wires ( I don’t know if that’s a good reading or if that’s even the way to read it ). I also used a piece of hose to listen to the solenoid, but did not here any ticking.
At this point I’m going to assume it’s the solenoid itself.
Has anyone had an issues like this? Does anyone have any ideas? If it’s likely the solenoid, is it serviceable?
Thank you in advance.
Alex

see if this helps.check your gas cap is tight and in good condition.

Manually energize the connector on the back of the solenoid to see if it operates. If it doesn’t then replace the purge solenoid.
You can read more about this code here..
http://www.obd-codes.com/p0441I haven’t heard of anyone servicing a purge solenoid, you will need to replace it if it is bad.
Thanks for link.
I think manually energizing the switch is a great idea, but I don’t know how many volts it takes. So if it’s not battery voltage how would I energize without possibly destroying it?
Thanks for you help.
I have a 1997 Dodge Ram 1500, 5.2L, V8 w/ 131K miles.
I had asked a previous question concerning code P0441.
I’ve gotten some good advise and links.
My specific question is concerning the purge solenoid valve.
When the valve is disconnected from it’s electrical connection and hoses and when blowing air (creating pressure) on either the vacuum side or the canister side – should the valve be closed and not allow any air to bypass, thus making that valve good?
Currently the purge valve I’ve removed from the vehicle is disconnected from it’s electrical connection and vacuum hoses. The valve is allowing air to pass through both the vac. side and the canister side. I’m assuming that it’s a bad valve?
Any help would be appreciated.
Thank You!
I’ll read to you from the troubleshooting tree for the purge valve
If all hoses are okay, start engine allow to fully warm up, turn off engine, disconnect the purge vacuum hose at the soleniod, that goes to the canister. start the engine, there should be no flow through the solenoid from 1 to 2 minutes.
The purge solenoid starts off in the closed position to block engine vacuum from the charcoal canister. When the computer wants to purge the system, it opens the valve by energizing it, allowing the vapors to pass due to the vacuum created by the engine.
If you have a solenoid that passes air when it is not energized, then I would say the valve is bad.
I doubled checked all the lines today – all look good. I reset the code. I performed test TC – 113A.
Warmed up vehicle to Oper. temp. Shut off engine. Disconnected hose going to canister. Restarted vehicle. The solenoid came on after 90 sec. and it seems to work correctly. Only issue is – before the 90 sec. the valve held a steady vacuum on the canister side. I don’t have a vac. gauge but when putting it up to my skin it held a vacuum. I took the truck out for awhile – no code. But I might need to take it out for longer period to complete it’s drive cycle.
The test says to go to “test 113-C” if there is a vacuum before 90 sec. I’m going to assume that the vacuum I felt against my skin qualifies?
The mil light has not come back and truck runs fine.
Does anyone have a link or instructions to test TC 113-C (1997 Dodge Ram 1500)? Or maybe this is suppose to be normal operation, considering mil light has not come back on?
Any other thoughts or suggestion would be appreciated?
Thanks to everyone who has commented about my topic. It has been helpful.
