Check Engine Light comes on--OBD tool says Incorrect Purge flow--code Po441, and PO446, vent control circuit. Does anyone know what to do here? - mherrmann33
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. - Visitor

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! - Visitor
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... - Visitor
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. - Visitor
