Intermittent failure of a purge control valve in the evaporative emission system can cause the Check Engine Light to illuminate. A failed valve should be replaced to correct this problem.

evap purge valve and charcoal canister

check engine light illuminated by purge control solenoid failure - $350 repair bill last month (8/10) or I would not have passed emissions testing coming up soon.

Check engine light came on, had Auto Zone test. Showed Evaporation System error, leak or blockage. We haven't determined which at this point. I was searching to find similar problems and how they were solved before we jumped into anything. Thanks for some great advice and I will check with Toyota on helping to fix. Great site!

Purge valve was replaced

CEL has come on two different times in last two weeks, once during high humidity after rain storm (tank was 1/4 full - checked fuel cap didn't correct right away but self resolved the next day after sitting over night)and second time during 94 degree day with high humidity and 3/4 full tank - released pressure at gas cap and CEL went off for a short while but came back on. Am going to get replacement factory fuel cal and drive at highway speeds to purge evaporator canister. If that doesn't solve the problem, will take to Toyota dealership to have them check the evaporator system and O2 sensor...

The code is P0441 and has not been serviced yet. My research shows this is a hard to diagnose problem and could be several things. No change in performance of the engine and MPG is the same.
1998 Toyota Avalon 124,000 mi,
codePO446 EVAP System circuit. Check engine light comes on and stays, tried changing the fuel cap.

this is the second time in one month that the same problem is there, different ventilator (there are three? of them)--last one cost us 234$ and now we have another. any way to shut off that warning light and live with an unnecessary evap system?
