P0449 code won't go away!!

[jaberocs]

Hey everyone. I ran a diagnosis scan because my SES light was on, and I get the P0449 (Evap. thing) code. I got this yesterday and all I had to do was tighten the gas cap even though it was already tightened. This time, it won't go away! I need to fix this ASAP as the guy who's buying the car will be here saturday. Thanks!

could be more than just the gas cap needing to be tightened.


thats just a first thought

did you have the computer reset?

P0449 sounds like a possible problem with the EVAP vent valve, or some wiring between the PCM and the valve.

i tried reseting my computer by disconnecting the neg. batt. terminal (right way to do it?), but my power stayed on. It was strange, I never had that happen before. I had the door open when I disconnected it, and the lights stayed on.

I have heard that the EVAP cannister beads will float or bounce up and block the outbound gas vapor tube causing the EVAP Purge control Solenoid to pop a code.

I hope that's the reason why it's acting all weird now.

disconnecting the battery will not erase a code. ;)

lol. i know, i was trying to reset the cpu. the ses light went away for like half a day even though i didn't do anything, but then it just came back.

The EGR valve (driver side exhaust) is probably sticking.

P0449 is EVAP, not EGR. They're not related in any way. [img]smile.gif[/img]

Turn the ignition to on and pull the pcm fuse under the hood on the drivers side. Wait for aprox 3 mins and turn the ignition off and reinsert fuse. If the code comes back it might be a defective cap.
