Jay :

Hello and thank you for using JustAnswer.com

Jay :

Those codes are Evap very small and Small leak codes.

Jay :

This is most of the time caused by the Evap Canister cracking by where the vent control valve mounts to the canister.

Jay :

This is where it cracks.

Jay :

If you have any more questions on this, please feel free to ask. Thanks Jay!

Customer :

thanks for the info...what is usually the price for this job?

Customer :

Jay what is usually the price for the job?

Jay :

The Canister is around 220 dollars

Jay :

the vent control valve if you can't get it off, will need to be replaced and that is around 180

Customer :

what is the urgency of getting this done

Jay :

1 hour labor to replace the parts so your looking around 500 bucks.

Jay :

It's not urgent at all. But should be repaired

Jay :

Cause since the Service Engine Soon light is on, if you get any other type of fault you won't know

Customer :

ok, Jay thanks a lot.........have a good day

Jay :

Jay :
