2007 Ford Five Hundred Question: emmisson light
Answer #1Brian Glastetter February 02, 2011, 23:21Master
Your emission light being illuminated does not necessarily indicate a oxygen sensor issue. It will be wise to perform a diagnosis since guessing is not cheap. Many emmission components have coverage beyond the normal warranty. Call the local Ford dealership and ask what coverages that might apply to your vehicle.
