I started getting a "service engine soon" light yesterday.
I aquired the codes through the procedure in the haynes manual. the codes were 0705 and 0309. both have to deal with the EVAP system. One code says system leak and the other one says canister vent control valve open. i manualy inspected the hoses and the canister itself, also made sure all elec connections were ok. I reset the codes and they came back today. Does anyone have any clues as to what could be the problem? 98 I30 60,000 miles

The Fuel evap control solenoid assembly fails and needs replacing...........should/ might be covered under 6/70k drivetrain warranty if you have been spending some money regularly at the dealers...........how is your permanent record.
Not real expensive to change $200.....pretty decent if this is your first emission failure 5-6 years.

Bad gasoline vapors......not really the solenoid but the valve attached to it...........notice I said assembly!
Not really part of drivetrain warranty but you are only a year over the full warranty........probably less time since this begins a first date of in service [to a retail customer] not build date.
Generally it is found that MTBE/ethanol attacks the valve.

Evap codes can sometimes be easy to diagnose, and other times can be kinda tricky. Especially when it starts involving numerous trouble codes. There are several things that come into play when dealing with evap codes. Performing a few tests using a consult II, can be a sure way of getting it right the first time. Q45 tech once posted a very good article stating that just because it has a particular code, doesn't mean to start replacing parts. In todays technology, and with all the tech bulletins we receive, you would be surprised on how many of the check light issues are related to connections, opens, shorts, updated parts and reprogramming. Not just replacing parts and hope for the best. I would get the proper diagnosis before doing anything!
