"Check Engine" light on with P0441 help ....pls
Question for Lexus experts, please help.
My 2003 ES300 (99K miles) has a "Check Engiine" light came on about a month ago after driving 4 hours straight with 90-100 miles/h.
I reset it by disconnecting battery for 20 seconds.
It was fine for a month. After another long distance trip, "check engine" light came on again.
I took it to the dealer and have them scan the error code.
P0441 - Evaporative Emission Control Purge flow
P0442 - Leak Detected (Small Leak)
P0446 - Vent Control Malfunction
Dealer suggested to replace:
1. Gas tank cap ($35)
2. Whole Canister Assembly ($260)
3. Purge Solenoid Valve (Valve, Vacuum) ($50)
These are parts only price, labor will be another $250.
Dealer reset it again, so "Check Engine" light is off now.
I am planning to replace the gas cap by myself right away.
Any suggestions, ideas, or your experience would be appreciated.
Thank you, fellow CL member...

I have the same codes on my 2000 ES. From extensive research, if all three of these codes pop up, the charcoal canister is the most likely culprit. I highly doubt you should have to pay someone to change it, it's only about a thirty minute job. GL!

replaced gas cap
OK. progress report.
I ordered and replace gas tank cap with new one.
Reset the error code by disconnecting battery. Engine error light came back on again about driven half tank of gas.
Next, I will try to change charcol (filter only) canister. fuel filter after that.
Can someone point out where it is on 2003 ES300? I am assuming that it is in engine room somewhere and changing is like (replacing engine air filter).
