I have a 1997 Rodeo 4x4. I clear the codes but the check engine light returns some times minutes after clear other times weeks. Here are the codes/ whay my actron pocketscan says. Anyone know quick fixes or what needs to be looked at?

P0440: Evaporative Emission System

Your EGR tube is most likely clogged. A lot of people blindly replace the EGR valve and it doesn't fix it. The p0440 is known as the gas cap code. Check your gas cap is on tight. http://www.obd-codes.com/p0440

Also check the vacuum lines at the firewall here:



There are two that go to the thing with the blue connector on top.

Thanks for the help. I felt a bit clueless on them.

My Canister Purge Solenoid only has the electrical conection and one line going out of it, it looks to be the vacuum line. There should be a return line correct?
