Must be an epidemic...... Same thing happened to me, 1 wire to EVAP solenoid completely split, the other 1/2 way there. Cut/crimped/spliced/wrapped and 150 miles later no light. Thanks lgeiger13

On my 2003 F150 I had a P0457. I got rid of that with a new gas cap. I still have a P1451 so I need to check the CVS for continuity. How many Ohms should it read and whats the best way to test that? My CVS is under the hood, bolted to the fire wall, very easy to get at. I've check the hoses front to back, no problems.

The more I read, the more confused I become, is the solenoid under the hood or back by the fuel tank?

The CVS is mounted on the charcoal canister above the spare tire. You're confusing it with the VMV (Vapor Management Valve) on the firewall.

Thank you! Now I just have to figure out how to get it down from there and check it. Thanks again

Where can I buy a canister vent solenoid? Looking online, all I find are the Vapor Solenoids on the firewall.

you could remove the cansters as one and check for cracks around the edge it should four bolts them just slide it out you will see once you get it i think it goes forwod and then down

Being that I'm not a mechanic, and this is all new to me, I take it you meant to say "It's a dealer item only".

Finally got it! Traced all the wiring from front to back, checked all the fuses, tested the Vapor Solenoid, and checked for kinks or blockage in the hoses. When I got the Canister Vent Solenoid off, it look pretty bad. Tested it and found it was bad, replaced it and now the check engine light has been off for a week. Also, got it to pass echeck .Thanks to all you guys for your help!!!!
