99 blazer evap emissions code
 

hey guys new on here just wondering if anyone on here has had this prob and can help

hmmm...what code? Number PO 440, PO 442, PO 446? JP

Depends which one. There are several evap codes.

I had a small leak code that went a away with a junkyard evap canister+bracket. My fuel fill line is also rusted through where it touches the frame, but the gorilla tape I put on there seems to hold vacuum for the evap system.

Mine went away with a new gas cap.

I can't remember which code was, but I noticed that it usually happened after I put gas. When the SES light was on, I removed and put the cap on as tight as I could and the light turned off after a couple.

With this in mind I bought a gas cap on autozone and never got the code or SES light again.

thanks
