i took the electrical connector loose and cleaned it, then cleared the codes. so far it hasn't come back on. i scheduled it for an oil change and service for next week. the guy on the phone said they would take a look at it, no charge.

You may want to check the gas cap after a ride to see if you get a little pressure building up in the gas tank. You should get some pressure right after a ride but not too long afterwards. You could have a bad cap seal or you may have fixed it with the connector you cleaned. Keep us posted as I am almost half way to that mileage - makes me glad I bought the extended warrenty but I would like to not use it so I can get that $1000 back in 5 years.

Actually, just running round with your gas cap loose might have caused that on some cars.

Edit: doh, he mentioned checking for that.

I'm surprised nobody's mentioned this so far.

Are you topping off AFTER the pump automatically cuts off? On 98%+ of the vehicles out there it floods the EVAP system with raw gas and causes these sorts of issues.

Naa I doubt that is the problem - I have had the gas flowing on the ground on my Scion xB and never had a problem with my emmissions lights - most people get a single light and error code when the gas cap gets loose and he got three so it probably was the connector. Had some rain and high water down there recently?? Drive through any big puddles?

1. First, check if the gas cap is a factory gas cap and it is tight.

2. If the fuel cap is good, then check the vacuum line to the purge solenoid located by the air filter plastic housing. If the lines are loose or pulled off, the code will set.

3. Next verify that the purge solenoid operates with the engine running. Back probe and ground the White/Green wire at the purge solenoid and verify that it will operate and apply vacuum to the canister assembly.

4. Test the canister closed valve on the canister, it has a Black/Red wire and a Blue wire. There should be battery voltage on the Black/Red wire key on and when the Blue wire is back probed and grounded, the valve should operate and close tight enough so the system can hold a vacuum. If all the valves test OK, test for a leak on the evaporative system.

Copied & pasted. Had to guess the year.

I had exactly the same error codes. Check for a vacuum hose disconnected from your air filter housing.

This thread is over 3 yrs old so I would be the issues have been resolved.

However I did notice that the O.P. said funds were tight yet he would take it into the dealership if necessary. If funds are tight you never take it into the dealership.
