2004 1/2 Kia Spectra Check Engine light on. Tested was told EVAP leaking.

Does my Kia's EVAP system need to be replaced? Can the EVAP be cleaned? Which part(s) need to be replaced?
Answer:

We can't jump to the conclusion that any parts on your 2004 Kia Spectra need to be replaced just yet. A smog repair station will need to trace the EVAP leak and determine where the leak is at. Maybe something as simple as a new clamp or hose (part of the EVAP system) is all that's needed, or the problem may be more severe requiring the EVAP canister or purge solenoid be replaced. The first step is to find out where the leak is at. Note also, EVAP trouble codes have been known to set with faults as simple as a loose gas cap. If your Kia Spectra's check engine light recently illuminated, you may want to ensure the gas cap is tight and drive your Kia for a week or two. If the EVAP code was triggered due to a loose gas cap, the light will turn off once the computer system realizes no real EVAP fault/s exist. If tightening the gas cap does not turn off the check engine light after two weeks, then certainly there is a defect somewhere within the EVAP system, and a hands on diagnosis will be required. posted by SmogTips Support
