A check engine light, rough running or poorer fuel economy can be signs of a worn oxygen sensor. Exhaust leaks and damaged wiring can produce these symptoms too, so find the cause first. With the engine off and cool, look over the harness and connector for cuts, melted insulation or loose plugs before you order.
