Yeah, it can. If something is wrong with your emmision control system, your car can still fail emmisons, but the check engine light doesn't have to be on.

Why does the check engine light still come on after the gasket was changed?
Did you reset the light? I don't know what gasket you changed, but undoubtedly that was not the problem. The check engine light comes on when there is a problem with the emissions system.
Why is check engine light on?
First rule of thumb is to check your gas cap; if it has been scewed on wrong, that will cause your light to turn on. Second, check your engine oil, you might be running low. Next, take it to a mechanic because it could be something worse. It could be anything; broken sensor, engine problems...take it to a mechanic you trust. Or if you still have warranty, take it to the dealer.

How long after you clear a check engine light can you pass emissions?
It depends what caused the check engine light to come on. If there is something seriously wrong with an emission control component, simply clearing the code will not effect the results of an emissions test - the car will probably still fail. On the other hand, some codes for minor problems might not even cause the car to fail.

Why would the check engine light be on in a Toyota Corolla?
Check your gas cap to make sure it seals tight. My check engine light comes on every now and then in my 1991 Camry and once I reseat the cap it goes out almost immediately. If this is not the problem have a mechanic check the oxygen sensor. Good luck, JFD EGR Va.ve? It might be your EGR valve which is part of your emissions system. My 1997 Celica passed the emissions test but the EGR valve still needed to be replaced. After it was replaced, the check engine light went off. The part cost about $75 from a Toyota dealer.
Will vtec still work when check engine light is on?
VTEC may or may not work when the check engine light is on. It depends on why the check engine light is one. If it is on because of a problem with the VTEC system, then, no, it will not work properly.
Check engine light stays on. Would the oxygen sensor still be the likely culprit if you only have 35000 miles on the car?
Unlikely. Could be as simple as a loose gas cap. Considering that the emissions warranty is still in effect, take it to a dealer.
