Anyone have a link to a list? Pulled a code the other night with a borrowed scanner.

P1456 Aux. Emissions Control

Anyone have this problem? The light has since gone off.

 

Hey I have that same code in my car. I dont know what it is either but the other day I went to a Shell Gasoline station and filled it up with Ultimate gas that has 10% ethanol and it came off the next time I started it up. I dont know if thats what made it turn off but thats the only thing I did differently. PM me if u get it figured out.

 

P1456 Evaporative Emissions (EVAP) Control System Leakage (Fuel Tank System)
i found that on google but i will check my esm tonight and see if there are any more clues.

 

Troube Diagnosis lists this as "EVAP VERY SMALL LEAK" so maybe your gas cap was on tight, just not tight enough?

 

Thanks guys. Yeah, I thought it might be the gas cap. The MIL going on seemed to coincide with filling up the gas tank and I checked the cap as soon as the light went on thinking that thats what it was. I was just wondering because the light stayed on for 3 days afterwards.
