My sister has an '02 Sunfire with the 2.4L. Took her car to EVS in the Falls (where she originally bought it new) for an oil change because nobody was around to do it for her. Her check engine light came on and she took it to Advanced to get the code run - came back as PO440 - EVAP Emission Control System Malfunction. Had her check her fuel cap first and made sure that was seated properly.

Any ideas on what she should do next? She's not very car-knowledgeable, so she is more then willing to take it back to EVS to get it fixed, but she wants to know if there are things she can try first.

Are there any vacuum lines or hoses that should be checked first? I don't see the car very often myself, but if I can direct her to look at certain things, she might be able to find something that way.

Thanks!
