140,000 miles - car passes emmissions test levels but fails because of these codes and misfire codes. The CEL is on, and from other post, I checked the following:
1) the gas-cap- it whooshes when I open the tank after being parked for 1 hour.
2) removed the canister - it's lightweight and dry, and does not appear to be cracked, but it had heavy gas fumes. Hoses look new and are tight.
3) solenoid valve at canister - tested fine. Connections are good.
4) upper solenoid valve at air filter - tested fine. Connections are good.
5) upper hose at air filter - looks good.
What's next to check? Any advice?

No advice but the same issue, replaced o2 sensors the last 2 years but not sure what to do this year. Just had van inspected and same errors po 420,440,441 and 446. Will try the gas cap as this seems the easiest and cheapest thing to try. 2 more payments and Im done but the level of frustration from dealing with this the last 3 years will probably make me trade it in.
#82 of 126 MIL and Power Window?

My Sienna 98 Malfunction Indicator Light (MIL) came on today. Gas cap was on tight. Two days ago the driver side power window would not work, but after a few hrs it did come back. Are these 2 issues related? Owner's manual says MIL can be either gas problem or electrical problem...

Do you have an OBDII scanner? Or can a local parts supply shop let you borrow one? The code helps troubleshoot.

Did you ever get an answer to your question bout the blinking red light with key? I'm getting the same warning light and have no idea what it means. I don't have a manual for the 2007 Sienna that I just purchased. I would appreciate any wisdom you could give on this matter! Thanks!

Any idea on how to reset the airbag flashing light? I reset the tire pressure monitor and mine has come on now for almost a week. Is there a way to reset this with a switch under the steering?
Appreciate a response ....Thanks

After an oil change should not the check engine light go off? How can it be reset?

check engine light and oil changes have nothing to do with each other.I don't think you can reset the engine light either

Do you mean "Service Engine Soon" instead?
I think you set the odometer to the total mileage, turn it off, then hold the button while turning the key to the On position. Something like that.

You are right. I meant the "Maintenance Reqd" light, not "Check Engine". I'll try to turn it out.
