OBD 440 Error and Check Engine light ON. Already replaced new Gas Cap, Solenoid behind Gas Tank. Still the Light comes on.

SOURCE: How do I reset the

If you disconnect your battery for 5-10 minutes this will most likely reset it. If it comes back on again, however, your computer is probably receiving a trouble code of some sort, and it would be worthwhile to bring it in to have the code read.

2002 toyota camry (4cyl) engine check light come on when I run high speed 80mph

SOURCE: check engine light went on because someone stole my gas cap

Theres two ways you could fix this issue. Disconnect the battery, let it sit for about ten minutes, or you can go to advanced auto parts, have them scan the car, and clear the code. Just tell them the CEL is on and they'll hook up the scan tool, then just ask them to clear it. That should solve the light problem in your car.

You should get the problem code ran at a shop or auto parts store. My moms 2003 Toyota Echo check engine light came on and it had a slight misfire, I replaced all the sparkplugs about $20 and no check light.

Hope this was helpful

I'm pretty sure 440 is an evaporation malfunction code. The cheapest cause is usually the fuel cap. However, there are evap solenoids that go bad over time. I believe there are three of them at around $50.00 each. Also check the connections where they plug in as they may have become loose or corroded.
