I was doing burn outs and messing around last Friday and on a hard launch my car threw a P0444 check engine code.

i reset code and drove around neighborhood without code coming back.

Has anyone experienced this?

 

Update: i fixed this issue in 2019 by replacing the vent solenoid purchased at autozone. The solenoid wouldnt cycle when energized. When i hooked it up to 12v it wouldnt make a noise. I cant remember what brand that i had purchased. Anyway all was good for about 2yrs and then i get a P0455 code. I tried replacing fuel cap but it did not clear code. I put the aligator jumpers on vent solenoid again to see if same thing was happening (not cycling) but no solenoid cycled fine. Then i pulled solenoid and used a hand vacuum pump( mity vac) to test for leaking. Solenoid was leaking. If i put my finger over other port it would hold vacuum. So i purchased a vent solenoid from Amazon instead of autozone this time. It fixed the problem hope this one last longer than 2 yrs

If they carry that part, FCP Euro guarantees their parts for as long as you own the car.

 

Thx. In hind sight it would have been better to purchase from them.
FCPeuro.com has it just a little more expensive. I paid $47 with free shipping on amazon. I think i paid similar price 2yrs ago from autozone..FCP has oem for $80.49. Autozone now is $110..
if this things fails again in a couple years, ill do it right and buy oem replacement from fcpeuro. The good thing is how easy it is to replace.
