The girlfriend just got home and her car is throwing a CEL. Can anyone tell me what this code means ...

P0456: EVAP CTRL SYS SMALL LEAK

Thanks guys ...

 

fuel evap line, Did she drive over anything? They rest near the frame rails usually on other side of the fuel filter. I wouldent drive with a leak, Any small spark could...well you probably already know..

 

Tighten the gas cap.

 

Nope. I'm hoping it's not the same old problem. The V6 S197s had a problem with the fuel pumps that would throw this code. However she already had this problem and had it fixed. I just hope it's not back ...

Yeah, I did that. I cleared the code as well. So hopefully it'll be good to go. She says she thinks it was a "little" loose. Hopefully that's it ... I don't need to deal with anymore crap right now ...

 

If it's not a loose gas cap, she best take it to a shop.

If you've never seen a diagnostic flowchart for an EVAP code, there's a reason a leak test (smoke machine) is used for that stuff.

 

Gas caps usually cause gross evap leaks. Taking a wild swag, I'd say the canister vent valve is stuck/leaking.

 

P0456 Its code for "should have kept your truck"

 

Errr try again. It's not my car.

 

 

Its code for "the mustang near me is 1001092918 times nicer!"
