I have a 2005 Camry with 143,000 miles and the 2.2 4 cylinder engine. The car runs great and I change the oil every 5k. The check engine light came on the other day so had the wife stop by a friend that has a code reader. He sent a note home with her that said "evaporative emissions". What are the potential candidates to cause this problem?

The description is not adequate. Get the trouble code number.

My car recently failed "Fuel Evaporative Controls".

But like Brian said, it is much more to know to diagnose the problem correctly.
