OBD II P0441

OBD II P0441

Postby gejettest [OP] » June 11th 2010, 6:47am

Hello,
1996 Safari van here, 227,000 miles, original owner, just changed my second set of intake manifold gaskets, and this code is now on. I did some research on it, any one else have this one come up? Is there a most likely suspect or place to start? I changed the gas cap, just to see if it was that obvious with a friends, no difference. Any parts or systems to test to find the culpret?
Thanks,
Henry

What scanner are you using to get this code? P0441 is a GM EVAP code, but I'm not sure it applies to your van. How about P1441, 'EVAP System Flow during non-purge'?
The price of paying attention is cheap considering the alternative.

Hi,
I'm using an Actron CP9175 OBD II AutoScanner, here is a picture of the fault screen.
I plan on pulling the doghouse off today and look for obvious things like connections, hoses, etc.
Thanks,

At first, I thought it might be a difference between your '96 and my '97. I'm leaning toward a difference in our scanners. The '97 FSM does not show this code. I would inspect the purge valve vacuum supply port (is there vacuum with engine at idle?), the purge valve itself, and the line from the canister to the valve. Please let us know what you find.

Sorry for the very late reply, but I did find the problem. It was a disconnected vacuum line at the purge valve. Reconnected it, no problem since.
Thank you all for your help.
