If the fuse is blown the N.O. EVAP vent valve will remain open = large leak. P0455.
if the fuse is blown the EVAP vent valve won't operate as designed. P0449

 

Ah! Thank you. Didn’t know it would stay open. Makes sense.

 

so the fuse is not blown now... however 449 is back... so i think im wire hunting at this point... does anyone have a wiring diagram for this?

 

nope but the code is back

 

The EVAP test takes some time and a drive cycle. I suspect the valve is shorting out when activated.

 

thats what im thinking too... so now i need to hunt down a wiring diagram... bc i have no problems getting 20 feet of wire and just running a brand new pair straight to the ecm

 

Why not just look at what you can see, that is the only exposed part, the rest is in the body harness under the seats. I don't know what good a wiring diagram is it just tells the endpoints. Usually it is in the connector or nearby it. Make sure somebody didn't try to use the adapter that comes with some replacement valves for 2006-2007 models.

 

Well i just removed this clown show i found about 3 inch off the vent valve burried in the wire loom... car has been running 20-30 mins now still no light... hopefully just tires and a drive cycle so i can pass NY inspection it will be back on the road!

 

It looks like somebody spliced a new connector in. That doesn't explain the fried wires.
I believe NY will allow 1 not ready test.

 

Two splices in each line , not soldered, was it taped at least , no shrink tubing? Two 1/2 a$$ed jobs done by 1 A$$Hat. Pitiful, just pitiful. This is an example of check the wiring, make sure it’s done right!
Glad you found that, now you can get it tested.
