Default Engine Codes

Just read my codes for my check engine light and got the following:

P0447 and P1668 Pending. P0447 refers to a Vent Control Circuit Open.

Any thoughts are greatly appreciated.

Thanks,
Chris

I think it pretains more to the evap system canister area more then the fuel cap, the 1668 I can't find.

P1668 = Anti-Theft Alarm serial link fault Drive cycle A:Signal out of range - above maximum.

However, I have no idea what it means.

Thanks...Anyone have a fix for this? Does the solenoid need to be replaced?

On the evap system you need to talk with a mechanic for the testing procedure, scanneer may clear the 1668 with no repairs.
